[linux-audio-user] ZynAddSubFX sound lags

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.
