[fluid-dev] About multi ( >2 ) jack outputs

[Giannis Gravezas]

First of all hello and congratulations on your fine efforts.
Fluidsynth is quickly becoming the best sampler on the linux audio 
landscape . The only thing that's been holding me from using it is the 
lack of multi-channel output ( I'm oriented on techno-trance and use it 
for percussion loops I need to be able to process each channel with 
different effects through jack and other apps ) . I tried specifying 
--audio-channels , --audio-groups and they didn't worked only two jack 
ports. Then browsing through the code I found in fluid_jack.c the 
"jack.audio.multi" and set it to yes and alas 36 ports !!! (16 stero 
channels) Only thing is when I try to play something  the synth exits no 
matter what combination I try. I browsed the code a little and seen that 
groups control the output but haven't browsed it extensively. Before I 
continue has anyone actually used multiple jack output? I wan't to know 
if I'm doing something wrong in my general setup before I try to 
understand how fluidsynth works .
Thanx in advance,
