Re: [fluid-dev] New patch: polyphonic key pressure (aftertouch)

[Kjetil Matheussen]

Great work! I've been meaning to implement this myself for many years but never got started. I'm going to apply your patch to the fluidsynth in Radium, since it has good support for polyphonic aftertouch, and see how it works. If it works, I'm going to keep it in the next release of Radium.

I've also looked briefly at the patch and it looks very fine to me at least. But I don't know the internals of fluidsynth that much.

Hi all,

I need polyphonic aftertouch for a project of mine and noticed that FluidSynth doesn't support it yet. So I've created a patch that adds that functionality. I have tested it with command line MIDI rendering and via the alsa_raw and the alsa_seq inputs. It does seem to work as expected. However, I would be very grateful if you could have a look at the implementation and check if I've made a mistake somewhere or if I've missed implementing it in other parts of the system.

To really test it out, you need a SoundFont with a Key Pressure modulator (my test font maps key pressure to coarse pitch). I've created a little MIDI file that plays two different notes on the same channel and send send lots of key_pressure events for only one of them. The result should be one note which stays in pitch, the other moves around in pitch. Please let me know if you want me to provide a test MIDI file and SoundFont.

Cheers,
