ok, thanks. I executed
fluidsynth -a jack -o synth.audio-channels=3 mysoundfont.sf2 and applied my reverb settings. Since my soundcard doesn't have 3 outputs, I mapped them all to one. I actually planned to record it with ardour later... However, I don't get any reverb at all. Setting synth.audio-channels to 1 and applying the same reverb settings and everything works fine. Apart from that, why is there actually a need for mapping all the reverb to output 0? Wouldn't it be more useful to map them to their corresponding output? Meaning, according to you example: Dry sound + reverb from MIDI Channel 1 to output 1, Dry sound + reverb from MIDI Channel 2 to output 2, Dry sound + reverb from MIDI Channel 3 to output 0, etc. Tom 2015-04-07 20:28 GMT+02:00 CERESA Jean-Jacques ENAC/ENAC <jean-jacques.cer...@enac.fr>: > Hi > 1) If you want to use more than 1 stereo channel output > you need to set "audio-channels" settings to the number of output you want. > For example, to use 3 outputs (assuming your audio card has 3 outputs!) > set audio-channels to 3. > 2) With this settings FluidSynth mixer dispatchs voices to the 3 outputs > depending on MIDI channel.
