any ideas?

You can run the soundfont_builder.rb file after modifying a little; something like this

def generate_midi(program, note_value, file)
  include MIDI
  seq = Sequence.new()
  track = Track.new(seq)

  seq.tracks << track
  # channel 9 + 1 is percussion by default
  track.events << NoteOn.new(9, note_value, VELOCITY, 0) # channel, note, velocity, delta
  track.events << NoteOff.new(9, note_value, VELOCITY, DURATION)

thx a lot, but this will not work on windows

Works for me in Chrome. In any case, you can just copy the sound files in the synth-drum folder in my fork to the appropriate place.

looking for Pre-rendered General MIDI Percussion soundfonts (Nrs 27-87),to rewrite this app:
https://github.com/letoribo/drums-io

I am also interested in acoustic drums/Percussion for my project. Has anybody built or found anything like this? Unfortunately I am also on Windows and unable to run the builder utility.

I have a few Percussion Sound fonts in a proof of concept project I had done. I think I just used one of the base 64 online converters and then copy and pasted over the current sound in the ogg.js file.

https://github.com/djlerman/midiclassjs

Thanks! I'll check it out. Are you saying that I can just take a regular mp3, convert to base64 and replace the sounds in the existing .js file? That sounds easy enough.

I think it needs to be an ogg file.

Here is an example. Take a look at the source code: https://iqaat.com/testScripts/ogg.html

Here is the code I used with midi.js. Silenced out all of the notes except the ones I needed.
https://github.com/djlerman/midiclassjs/blob/master/soundfont/steel_drums-ogg.js

Yep, you were exactly right. I've got it working using some drum samples I had laying around. Loving this thing!

these soundfonts created by converting from
*** GeneralUser GS v1.44 *** http://www.schristiancollins.com/generaluser.php
can be found in this repo:
https://github.com/letoribo/General-MIDI-Percussion-soundfonts-for-MIDI.js-

this is MIDI.js version of Paradiddles System:
https://www.npmjs.com/package/drums

and this is a demo: https://drums.herokuapp.com/

many thanks

The builder is a simple ruby program to run fluidsynth to render the sound font to WAV, then lame to make MP3 and oggenc to make OGG. If you could get those tools on Windows there's no reason why it wouldn't run there?

MIDI.js needs hacking to load a drumkit patch set also. The drumkit is not in the normal instrument range 1-128 and MIDI.js has no concept of it as-is.

I don't see that we have to use a different soundfont: the FluidR3 font at least does seem to contain percussion instruments just fine. All I had to do in #187 was change the soundfont builder to use channel 10 in order to extract these. I guess dedicated percussion fonts might have superior quality in some cases, but is this the motivation behind what people have been doing here so far?
