"Problem" solved: I had ZynAddSubFX's internal sound buffer size set to
1024.
With 32 there's practically no lag whatsoever. :)
Quoting juuso.alasuutari(a)tamperelainen.org:
I'm driving ZynAddSubFX from MusE with ALSA MIDI
& JACK on a 1.7 GHz Pentium
M
laptop and a 2.6.17.11 kernel with the realtime-lsm module. The sound lags
behind ever so slightly; I have to move the notes backward one 32T to be more
or less on the mark. And even then it sounds like there's a certain
randomness
to when each note is played.
Is ZynAddSubFX such a monolith that this isn't avoidable without a more
powerful
computer? Or should I try enabling the (supposedly broken) JACK_RT audio
option
during compile? Anything else I could do?
If I've no hope of getting ZynAddSubFX to not lag, can someone recommend a
good
additive synthesis alternative? Preferably something not modular; I want to
twist knobs to create sounds, not to build a new synth from scratch.
Thanks,
Juuso
