Virtual Playing Orchestra is a full, free orchestral sample library featuring section and solo instruments for woodwinds, brass, strings and percussion. Click the buttons below to learn more, to download the library and to hear a few compositions using the free orchestral instrument sounds that are available.

Download Virtual Playing Orchestra 3.2.2

Virtual Playing Orchestra consists of 2 parts: wave files and scripts. These two things work together. The scripts configure the use of the wave files. You need to download the “Wave Files” plus at least one of the “Standard Orchestra” sfz scripts or the “Performance Orchestra” sfz scripts (depending on how you want to control the sounds) then unzip each zip file in the same place and in the same way as you did with the wave files, or wherever your DAW (digital audio workstation) can find the files you unzip. Either way, all .zip files need to be unzipped in the same place and in the same way (i.e. extract the .zip files into the same sub-directory, “Virtual-Playing-Orchestra3” for example).



Wave Files

[ Version 3.1 ]
(works with sfz scripts version 3.1 -> 3.2.2)
download virtual playing orchestra wave filesThe Wave Files download contains the raw sound of each instrument.

Sfz Scripts

Sfz scripts map the raw sounds from the wave files to MIDI notes and also shape and enhance the sounds.

Standard Orchestra

[ Version 3.2.2 ]
(still works with wave files version 3.1)
download virtual playing orchestra standard scriptsThe Standard Orchestra uses key velocity (how fast you hit a key on your MIDI controller) to control the volume. Articulations (sustain, staccato etc) are placed in different tracks or are selected via key switches. Most virtual instruments work this way.

Performance Orchestra

[ Version 3.2.2 ]
(still works with wave files version 3.1)
download virtual playing orchestra performance scriptsThe Performance Orchestra uses the MOD wheel to control volume (some professional sample libraries work this way). Key velocity (how fast you hit a key on your MIDI controller) selects the articulation (sustain, staccato etc) while still slightly affecting the volume. The performance .sfz file names contain the string “-PERF”.

What Is Virtual Playing Orchestra?

Virtual Playing Orchestra is a free orchestral sample library, in sfz format, that attempts to emulate multiple articulations of the solo and section instruments from a full orchestra using the best free samples from Sonatina Symphonic Orchestra, No Budget Orchestra, VSCO2 Community Edition, University of Iowa, Philharmonia Orchestra and extra free samples from Mattias Westlund, author of Sonatina Symphonic Orchestra.

The plan was to start with Sonatina Symphonic Orchestra, add new samples from Mattias Westlund and samples from newly available sources that had recently become available to create what I would like to see from a Sonatina Symphonic Orchestra 2.0.

I’ve listened to every single sample that made it’s way into this library (and continue to do so as I use this sample library in my own music), and have done my best to replace any noisy samples, ensure each sample plays in tune, each note peaks at about the same volume and is panned in the center of the stereo field. I’m hoping this scrutiny will result in me being able to provide the best, most complete, free orchestral sample library available.

Virtual Playing Orchestra FAQ

To install updates, just unzip the files in the same place and in the same way as your previous version, to upgrade to a new release. When asked if you want to overwrite or replace files, say yes. It is what you need to do to install a new version.


  • ALL sustain samples are looped. Use this power responsibly! These samples were not looped to create musicians with infinite lung capacity but instead were created because many of the samples were too short.
  • Section and solo instruments
  • Sustain, normal, staccato, accented articulations for all strings, brass, woodwinds
  • Pizzicato for all strings
  • Tremolo for all strings sections (plus tremolo for solo violin)
  • Articulations can be loaded individually or as part of a key switch patch (in the standard orchestra)
  • Articulations are selected based on how you play a note (in the performance orchestra)
  • Round robin for staccato strings to simulate up and down strokes of the bow
  • 2 velocity layers for trumpets, french horns, trombones
  • A light randomization of pitch and volume when repeating notes, like real players
  • All samples have been checked (and corrected if necessary) for tuning, panning issues
  • All samples volumes have been equalized so max volume is approximately the same value
  • All instruments are set to only play within their proper note range
  • All instruments (in the standard orchestra) include a general purpose articulation called “Normal-mod-wheel”. This is effectively a sustain patch with a fast attack, but the mod wheel reduces the rate of the attack, for the times when you don’t want the slower crescendo of the sustain patch, but you still want a sustained note.
  • General purpose patch for full string section (violins + violas + cello + bass in a single patch spread across the keyboard)
  • General purpose patch for full brass section (trumpet + french horn + trombone + tuba in a single patch spread across the keyboard)
  • General purpose patch for full woodwinds section (piccolo + flute + oboe + clarinet + english horn + bassoon in a single patch spread across the keyboard)


  • REVERB! – These instruments are from multiple sources. To make them sound like they belong in the same room, and to make them sound more like real orchestral instruments, REVERB IS ESSENTIAL.
  • An sfz player. You load .sfz files (these control how the sound samples are to be used) into an sfz player (listed below), in order to play the chosen instrument.
  • Suspension of disbelief. With free orchestra samples, there are limitations. I tried to do the best, with the best samples that were available to me.

Supported Sfz Players

This library is known to work with the following .sfz players. It may work with others, but I don’t know. If I’m told it works with others, I’ll list them here.

Sforzando, Garritan Aria Player, LinuxSampler*, MuseScore, sfizz

* with LinuxSampler, in key switch patches, default selection of a sound (typically “sustain”) doesn’t automatically work. A key switch key must be pressed before any sound will play. Also, patches that use the MOD wheel (.sfz files with MOD or PERF in the name) may not work properly since linuxsampler apparently doesn’t permit any controller to control more than one parameter at a time however, I’ve been told that editing the .sfz files and replacing “gain_cc1” with “volume_oncc1” solves the problem. (thanks to Kevin Haines).


Unzip the downloaded files somewhere that your Digital Audio Workstation (DAW) can find them, then load whichever instrument .sfz file you want into your sfz player (like Sforzando) within your DAW.

You must unzip both the zip file for the .sfz scripts and the zip file for the .wav files to the same destination and in the same way (i.e. extract the .zip files into the same sub-directory, “Virtual-Playing-Orchestra3” for example). If you are asked to overwrite files, say yes. This library requires both downloads (one of the .sfz script downloads and the .wav download) to function.

If you have installed and unzipped the files correctly, you should have a sub directory called “Virtual-Playing-Orchestra3” containing folders like this:

Virtual Playing Orchestra - install directory

*** The “libs” directory must be present as shown in the picture above ***

So, if everything is installed correctly as show in the picture above, all the directories: Brass, Documentation, Keys, libs, Percussion, Strings, Vocals and Woodwinds are in the same place. If not, then you need to move them into the same place.

The “libs” directory contains all the .wav sample files (the actual sounds of each instrument). The other directories contain the various scripts (which use the .wav files) for each orchestra section.

How to use

To use the instruments in this orchestral sample library, it’s necessary to have an sfz player. This is a plugin for your DAW (Digital Audio Workstation) that can read the .sfz files, load the .wav samples and play back a sound when a key is pressed on your MIDI controller. You will have to explore the .sfz player to understand how to load the .sfz files but one way, at least with the free Sforzando sfz player, is to simply drag and drop a .sfz file into Sforzando.

I’ve provided a few different .sfz variations for each instrument. There are SOLO files, where it’s the sound of a single player, there are SEC files for the sound of multiple players playing in unison. There are a few articulations (methods of playing) such as:

  • sustain – long held notes that start slowly
  • staccato – short choppy notes
  • normal MOD wheel – long held notes that start quickly but the MOD wheel can adjust how quickly the note starts
  • accent – an initial quick sound followed by a slightly delayed sustain
  • tremolo – for the strings only, this is similar to the sustain but the player shakes the bow back and forth while playing the note
  • pizzicato – for strings only, the player plucks the string
  • DXF – only available for trumpet, french horn and trombone in the standard orchestra, these patches use the mod wheel to control the dynamic cross fade between quiet and loud samples for a given note as the volume increases with the movement of the mod wheel.
  • KS – these are key switched patches. Rather than needing to load each of the above into a separate instance of a .sfz player, load a KS patch instead and use a special MIDI note to change which articulation will be used. Key switched .sfz file names are in the form KS-XX. The XX indicates where on a MIDI keyboard the key switches start. KS-C2 for example, indicates that pressing C2 will cause the sustain articulation to be used. See the documentation for the Standard or Performance libraries (links in the download area) to learn which keys select which articulation for each instrument

  1. First of all, thank you for putting this together!
    I have 2 questions:

    1) I want to use the MOD wheel with the Performance Orchestra, so I can regulate the articulation without changing the volume. Because (as illustrated in the video) if I’d used the Standard Orchestra, making ‘natural’ notes would always have an increasing volume (too noticable). Only I don’t have a physical MOD wheel, so I have to manually change it in the CC01 envelope for each note (which is doable with a lot of copy-pasting but very irritating for long tracks with a lot of notes). Do you know if there’s a setting in VPO, Sforzando or your standard DAW (I use Reaper) that does this automatically when a note is struck? This question isn’t directly related to VPO, but I can’t seem to find an answer online.

    I also have a question regarding the track envelopes using .sfz files in Sforzando.
    I wanted to change the effects, but I only saw envelopes for the controls and a ton of MACRO_000 envelopes.
    I know I can use a seperate ADSR VST, but if possible I’d like to stick with the Sforzando effects. Is there any way I can find their envelopes?

    Lastly, do you know what these MACRO envelopes are? Are they bypasses for each sfz. file? If so, is there a way to determine e.g. MACRO_219 as it’s specific sfz.file?
    (Then maybe I can use multiple .sfz files in one track, instead of bypassing different Sforzando instances or having a lot of tracks. But then again seeing one answer where you said you have to have an instance per .sfz file, I don’t think this will work, it is a very far-fetched hypothesis.)

    Thanks in advance!

    • 1. Do you have any other slider or anything that sends CC messages? You could use Reaper to configure a CC controller to send CC01 messages so that the other controller would function as a MOD wheel. Beyond that, I recommend posting a message on the Reaper forum for ideas on how to do what you want. They’d be better able to help.

      As for you question about changing effects and MACRO_000 envelopes. I’m sorry but I don’t even understand the question. To me, effects are things like reverb, and compression that I’d add to a track in Reaper and are not related to the .sfz files or Sforzando, so I don’t understand what you are asking.

      If you want multiple .sfz files per track, you can fake that in Reaper. You’d still need an instance of Sforzando per track but you could have a single track sending it’s MIDI to multiple tracks, then simply disable the display of the tracks you don’t want to see using Reaper’s track manager. It would then appear that the hidden tracks don’t exist.

      • Thanks for the quick responce!
        I don’t have any hardware for music production, so reaper forums it is.
        Those MACRO’s are indeed very weird and I can’t find anything on it online so I’ll leave it at that. But just so I don’t sound crazy I’ll leave this screenshot showing what I meant :).
        Didn’t know you could send MIDI to other tracks! Makes it much cleaner.
        Thank you!

        • I’m curious about the MACROs, but the image requires special access, so I can’t see it.

          Here’s a possible solution that would enable you to use the mouse wheel as a mod wheel (paraphrased slightly from the Reaper forum)

          Insert ReaControlMIDI upstream from your plugin, enable sending control change messages, set one of ReaControlMIDI’s sliders to send mod wheel. Then you can use the FX parameter learn (under the Param menu on the FX window) to map those sliders to the mouse wheel.

          • Thank you so much, it worked!
            Never thought about mapping it to my mouse wheel, will use this a lot 🙂
            Also sorry about that image, it’s now public, still wondering what a macro is. The only thing that comes to mind is ‘macro code’ used in programming.

  2. Why is it that the library lacks a lot of notes for me to put into my music? I tried hitting from many ranges LMMS normally covers with an Audio File Processor track and it couldn’t even play that! And it isn’t even about DAW compatibility regarding this!

  3. Thanks a lot for the soundfonts, it may not be the quality an expensive high end Kontakt library but it’s the next best thing and I love it. Been using it for all of my orchestral needs and it’s doing its job!

    One thing that it seems to lack is a way of doing smooth legatos. Unless I’m doing something wrong, those flute runs are currently not sounding too doable. Any plans on working on that? I’ve heard that making a truly reliable legato is tough, but there should be a way to do it at least a little better than we have.

    • A while ago I experimented with creating a legato articulation and what I found was that there wasn’t much improvement over just overlapping adjacent notes with the sustain articulation. I really couldn’t hear any significant difference so I abandoned that.

  4. Hello, thank you for this great sound library. An essential feature I’m not quite sure about how to accomplish, is the smooth glissando (aka. portamento, aka. pitch bend). I’m using Ardour and I am attempting to make a LARGE glissando on a string instrument that ranges over about 2 octaves (so the “Bender” automation wouldn’t work). Using a Pitch plugin with automation sounds like crap, but maybe I’m doing it wrong.

    Using Sfizz with Ardour and the Performance SFZs, could you help me accomplishing a smooth glissando just like real string players would do it? Thank you!

    • I’ll be very surprised if it’s possible to make a 2 octave glissando or portamento sound anything approaching real. To build this library some samples have been stretched up or down a 3rd but that’s about as far as it can go before sounding bad. I’d like to be wrong but I think you’re attempting something that just won’t work. Wish I had a better answer for you.

      • Could it work if you used multiple samples in a clever way? I don’t know if it sounds good enough or if Sforzando supports it (i think it should?) but idk just throwing ideas

        • If it’s possible at all, I think it would be very difficult with the sfz format. Not only would multiple samples need to be triggered in rapid succession but the rate at which the samples are triggered would likely need to be adjustable based on the tempo of the music or based on the duration of the glissando.

  5. Hi, I’d like to use this library, but I don’t seem to have got the folder structure correct, thus I’m not hearing any sound when I load an SFZ file. However, I cannot have access to the picture that shows the folder structure. Would you mind giving me a quick run-down in plaintext?

    • I’m surprised you can’t see the picture but, in plain text, what the picture shows is that the directory structure needs to look like this:


      Note that the libs directory is in the same place as all the rest of these directories. The libs directory is where the sound files are kept. It’s the libs directory being in the wrong place that is likely the reason this isn’t working for you yet.

      • Oh I got it now. Thing is I’m registered blind/low-sighted, and also don’t have a computer monitor, so the confusion came from there. Cheers for the help!

        • Ah. I thought maybe there was a problem with my web site and the image was not appearing for you due to some error. Hope you have everything sorted out and will be able to make some music!

  6. I had used these before and got them working, but now that I had to get files back now they aren’t working anymore, FL Studio keeps saying the folders are empty except the libs and documentation folders.

    Idk what to do

    • It’s likely the directory structure is not correct and the files are not where they are supposed to be. See the picture in the installation instructions that shows where all the files need to go. Ensure your directories match those in the picture.

    • A few people have had this same problem. There are 2 solutions. When unzipping, explicitly tell the unzip tool to use the same unzip target directory for the wav and sfz files rather than letting it choose the directory. Or let the unzip tool unzip the things wherever it wants and then just move the wav files directory into the sfz subdirectory to make it match the picture in the install instructions.

  7. I have only played around with VPO a little in Reaper but so far I am delightedly impressed. This orchestral library seems to be state of the art and free! I plan to try and use it for a music video project that I have just started working on and need some really nice violins for. I will post a link here to the completed mv when it goes online.
    Thank you so much and well done.

    • I’m glad to know my library will help you with your project. And yes please do post a link to the video when you are done. I’m interested in seeing it.

  8. Hello! Thanks for this great tool! I’m curious, is it possible to apply this VPO to a score in Musescore that I have already written? Or does it need to be used in a new document?

    • Can i add as a musescore user. In musescore i create my score. Once completed I export either as a midi file or an xml file (musescore seems to have a fee problems with this format). Import the midi file into your favourite DAW. I use Cubase. I then create a new instrument lane below the midi file. In the drop down box (cubase 10.5) select Sforzando or plogue. Load the instrument that you wish to you use eg virtual Playing Orchestra Brass Trombone. Next cut the midi file from above and paste into the instrument lane that you created. You can now use the instrument. You can apparently import sfz into musescore but why would you do that because your DAW either paid for or free has more editing tools than musescore hence i export it.

  9. Dear Sir.

    I don’t like to look a wonderful gift horse in the mouth – but is there any way of NOT needing about 40 instances of Plogue Sforzando to do the whole orchestra? I don’t know if it’s possible to combine scripts, or if there’s something similar to Plogue that lets you use more than one SFz at once so you don’t need a ton of instances of it?

    Sorry for 2 questions but they are related. Found something at RGC Audio called SFZ+ which DOES look like it lets you load more than one instrument at once – but I can’t make it load SFZ files, only soundfonts. What am I missing here? (Apart from a brain – that fell out my ear years ago when I forgot to put the cotton wool in!) Anyway, do you know anything that can load several SFZs in one instance of it?

    Yours hopefully


    • As far as I know you must load one instance of Sforzando per .sfz file that you want to load. I recommend loading up all the instruments you want to use with one instance of Sforzando per track, then saving that as a template in your DAW (Digital Audio Workstation). Then you can load the template and everything will be automatically set up for you next time.

      With Virtual Playing Orchestra, if you want a combination of instruments on a single track, try the “all-brass” “all-woodwinds”, “all-strings” patches.

      As for sfz+, yes it’s different. It loads soundfonts, which is not the same thing and my understanding is that sfz+ doesn’t support all the features of sfz.

  10. hi Paul, very thanks for this free orchestra. I use this with musescore, but some instruments have a sound elongation problem. the sound suddenly cuts out, how can I solve this? Thanks

  11. Is it possible to use these sounds with Qtractor? I have midi files generated by Lilypond (music-typesetting software) which I would like to edit in Qtractor. At the moment I only have fluidsynth and freepats soundfonts, and some of the orchestral sounds are poor. But I simply don’t understand what I would need to do to use VPO in this environment, or even if it’s possible. I am currently running Ubuntu 18.04.

    • I don’t know anything about Qtractor but after a quick search I found a couple of links that might lead you in the right direction.

      SFZ Player for Linux

      Linux system set up

      Both of the above links are from people trying to use Virtual Playing Orchestra with Linux. The second link specifically mentions Qtractor.

  12. Dear Paul,

    Thank you so much for providing this sound library. I’m a newbie and have no experience with either notation software or DAWs, although I do read music and play several instruments. I’m trying to convert my grandfather’s handwritten string-quintet compositions from the 1950’s into music files. I’ve copied them into Finale, outputting them as MIDI files into Reaper, and am using your strings samples as VST’s. With any luck I should be able to produce some lovely and sentimental music for my family this Christmas.

    Thank you and Cheers!
    Christine 🙂

    • Thanks for sharing your story. Always glad to know how someone is using the sample library. Also, you might have been able to save yourself a step as Reaper has a music notation interface. Although I can read music, I’ve only just glanced at the music notation interface a little bit in Reaper (I’ve grown very accustomed to the piano roll) but it might be useful to you.

      • An addendum to the above if I may, cakewalk, by bandlab is another DAW that has notation capabilities included although how good it is I do not know as I have not, as yet explored that option.

  13. Hello. I have confirmed that Virtual Playing Orchestra 3 works with TX16Wx 3 Free Ver. I can report here. The keyswitches and velocity layers are visually apparent. The round robin and crossfade were unknown.
    Unlike Sforzando, the sound quality was good. I was surprised. Thank you.

  14. Hi, many thanks from me as well for putting this together.
    I must admit that I was a bit daunted as well by trying to get this all work, because it involves making several different applications work together.
    For what it’s worth, here’s how I set up Virtual Playing Orchestra to work in Logic Pro (on a mac), maybe it’s of some use to someone:

    – downloaded the wave files and the .sfz packages from this site and unzipped them as described above (together in one directory)

    – downloaded and installed the Sforzando plug-in from the plogue website

    – after restarting Logic, it recognised Sforzando as an .au (Audio Unit) instrument

    – I could then create a track with Sforzando as instrument, and import one of the .sfz files in the Virtual-Playing-Orchestra3 directory.

    However, it felt a bit clunky to have to import, browse to, and open a .sfz file every time I want to create a track (or change it). I figured it should be much nicer to have them listed inside the Sforzando “Instrument” menu. It turns out that that’s very easy:

    – move the Virtual-Playing-Orchestra3 directory to a suitable place (I used ~/Library/Audio/Virtual-Playing-Orchestra3)
    – open the Sforzando plugin (or standalone app)
    – click on settings
    – look for the box labelled “User files path”, click the “set” button to the right of it
    – navigate to the place where you moved the Virtual-Playing-Orchestra3 directory

    After that, they all show up in the menu if you click on “Instrument” (top left), under “user”, and in the proper categories too 🙂

    • I completely agree that getting this to work can seem daunting but not so unusual for .sfz based instruments. For anyone wanting more info on why there are multiple downloads, see the “Why are there multiple downloads” on the FAQ page. Thanks for explaining about the “user files path” within Sforzando. I would also recommend, creating a template so that when you start a new project, you can load the template and all the instruments are automatically loaded onto their tracks and ready to go.

      • I suppose it’s indeed not harder than any other .sfz instrument to set up; but this also happened to be the first time I ever dit that 🙂

        Great idea re. the template: I actually found two such templates yesterday for Spitfire Audio’s BBC SO Discover and it looks like a huge time saver indeed.

  15. Thank you for your prompt reply. I was able today to read it and tried opening the script files with a text editor, which my Mac had not been doing on its own. Everything seems to work correctly now. Thank you so much!

  16. I have exactly the same problem as Phoenix above. I also have a Mac.

    I installed the wav files successfully, but when I unzipped the scripts, all of the folders labeled for each instrument group contained sfz files that had the black-square icon with the word exec on it. My free sforzando player will read and play the wav files but will not read any of the scripts. I unzipped both right on the desktop, and had to move the “libs” and the “Documentation” folders to match the picture in the installation directions. I tried downloading them again and unzipping them in a directory where I have other sound libraries stored, but the same thing happened.
    However, I notice that, although it looks as though I unzipped the scripts correctly judging from the folders that appeared and their (unreadable) contents; still, the original zip file is still on the desktop, looking unzipped–as if I only unzipped a type of copy rather than the original. I was not prompted as to whether I wanted to overwrite existing files, either.
    I can still use the wav files in the sforzando player, but I find it very difficult to use an instrument that plays only one note at a time, and I have to load another to play a higher or lower tone on the same instrument. This is not, I hope, the way it is meant to work.
    Any help would be appreciated.

    • A couple of things. First, the .sfz files are text files. If your Mac is treating them as something else, I don’t know enough about the Mac to help with that. Also, when unzipping, the scripts and the wav files, tell whatever tool you are using to unzip them, to place the files in a directory called Virtual-Playing-Orchestra3, or some other name of your choice but ensure you specify the exact same target directory name when unzipping both files. After that, you should be able to drag and drop a .sfz file into Sforzando and have each key on your MIDI controller play a different note from the chosen instrument. You should never need to load up any .wav files yourself. One more thing, are you able to open an .sfz file with a text editor? You should be able to do that and see a bunch of text, otherwise something bizarre has happened during the unzipping process.

      • An ‘exec’ label on a Mac means it is (or the Mac thinks it is) a Windows file. Make sure you download this to a location where the Mac expects to find a document file (ie, not in Applications or directly into the System Library folder). For organizational purposes, make a new folder and download your zips into there – then when you unzip you will have both the zip file and the unzipped folders in the same place. (Mine unzipped to identical folder names, so note the contents.) Copy these into a place where you can connect them to your notation program or DAW. Here’s where I put mine.

  17. Hello.
    Thank you for the wonderful sound source.

    I am a beginner. I used to use SC-88 Pro and a Recomposer in the old days.
    I checked the operation of VSCO 2, but it did not work in my environment, and it worked with the combination of SoundFont version and sforzando.
    At that time, I learned about the existence of Virtual Playing Orchestra. And there are some reports.

    The volume for each articulation is not the same in cello and viola sections and solos.
    “Sustain” sounds small, “Staccato” or “Tremolo” sounds loud.
    Since the tremolo playing method moves the hand in small steps, it cannot produce a loud sound.
    The “Sustain” of strings is like Slow Strings. I was a little confused.
    The “Normal Mod Wheel” sounds like Sustain.

    I wantthe volume to be the same even if the playing style is different.
    In this regard, VSCO 2 seems to be a good example of volume balance.
    Strings “Staccato” sound like “Spiccart”. The sound is too intense.
    It may be better to separate this sound from the staccato playing style and install a new spicart articulation.
    VIOLINO-detaché, legato, portato, staccato, martellato, spiccato, gettato e bariolage

    This does not have the vibrato technique that VSCO 2’s sfz has.

    Sounds like brass strings are included in brass instruments.
    Is this because it depends on the original sound source?

    I had be happy if you could reflect something close to nature like VSCO 2.
    Difference between “trumpet-SOLO-sustain.sfz” and VSCO 2 “Trumpet SusVib.sfz”.
    Difference between “cello-SEC-sustain.sfz” and VSCO2 “CelloEnsSusVib.sfz”.

    There is no key switch for “all-strings” and “all-brass”.
    Is it difficult to install the key switch?

    There is only a minimal amount of Control Change required.
    Is this a specification?
    I edited the SFZ file as a layman and it sounded like the attack time and release time were not working.

    Also, I would be happy if the Control Change number was not something like “CC01” but an easy-to-understand word. User friendly is important.

    The track envelope shows a large number of numbers.
    Is this a sforzando specification?

    Uploaded screenshots and comparison sounds.

    • You have a lot of questions. Some I don’t quite understand. I’ll address some of your notes. I did the best I could with the free samples I was able to find. I tried to get the volumes to be the same between notes and between instruments and all playing styles. CC01 is the Mod Wheel. That’s it’s easy to understand word. Yes the sustain strings are like slow strings. The “normal mod wheel” strings are also sustain, but with a faster attack that can be adjusted by using the mod wheel. There are no key switches with the “all-strings” and “all-brass” for two reasons. I wanted all key switches to fit within a 61 key MIDI controller and the “all-strings” , “all-brass” use up the whole 61 key range and the “all-brass” , “all-strings” are meant for working out ideas to later be replaced by individual strings and brass instruments so I figure there is less of a need for key switches. Hope that helps.
