I played a bit with it, and it seems to work fine. I only selected
patches and played them on the keyboard, though. Someone (Will Godfrey,
perhaps) should stress test it with heavy load and see wht happens.
A thing that struck me as odd: Why do I have to specify my jack
buffersize, when zyn obviously knows what it should be:
[atte at vestbjerg ~]$ zynaddsubfx
Sample Rate = 48000
Sound Buffer Size = 256 samples
Internal latency = 5.3 ms
ADsynth Oscil.Size = 1024 samples
AudioOut, zynNframes 256, zynSamplerate 48000
Error, zynNframes 256 != jack buffer size 128 => bad
Error, failed to open audio out on 'default'
So instead of me having to go "zynaddsubfx -b 128", the program should
know that the only sane buffersize with the running jack server is 128
and then use that.
I'm not sure if this behaviour is new, but I don't seem to remember this...
