The way zyn works pushes the bounds of good sense in terms of actually
generating it's sound in realtime, but you gradually learn the limitations
and how to have fun within those limitations. The main difference with
yoshi is the audio/midi drivers plus some refinement (nothing radical)
to the sound generation processing cycle. So far, yoshimi does both the
drivers and the generation cycle better than original zyn, but I think
we'd all like zynaddsubfx to catch up and get it right at last. Frankly
I can't see that happening any time soon, but I am a registered cynic in
that area.

And I think I can predict the results. If you're running a whole bunch of
other apps on the same system at the same time as zyn/yoshi, then the cpu
grunt available to zyn/yoshi is going to reduce accordingly, and so is the
level of sound complexity you'll be able to achieve in realtime. Currently,
yoshimi sets the priority of the midi and audio threads to 50 (or 55, can't
remember), and they're competing for cpu with everything else you've got
running SCHED_FIFO.
If you really, really, really want the sounds zyn/yoshi can produce, then
you learn to accommodate its demands and limitations in terms of resource
availability. If you can't accommodate those requirements, then you really
need to use a different synth.
cheers.
