Excerpts from James Morris's message of 2010-07-07 10:42:31 +0200: Tried with that instrument. I wouldn't call it 'falling asleep', it's chewing all CPU it can get and needs a SIGKILL to stop.

[ .. ] Oh dear ... what you're describing hints at maybe another deadlock on loading a padsynth instrument. Perhaps there's more required than I found for the fix in 0.057-rc2 -> 0.058. I'll look into it, see what I can do :-(.

With plinky-plank's sample-quality->samplesize of 5, it sets about prepping an fft plan on 512K, and any way you go about that I figure that's going to take a finite chunk of time. My terminology use here is no doubt way off, I don't pretend to understand as much as I'd like on the subject of fft processing. The "problem" was that somewhere way back there I switched the planner flag from FFTW_ESTIMATE to FFTW_MEASURE, and as the docs put it, "FFTW_MEASURE tells FFTW to find an optimized plan by actually computing several FFTs and measuring their execution time. Depending on your machine, this can take some time (often a few seconds)". On my AMD250/4G ram, plinky-plank took all of 1'24" to come to life. And wasn't it worth the wait! By switching the planner flag back to FFTW_ESTIMATE, things happen a whole lot quicker. This one is just further evidence that when it comes to the core synth stuff, Paul (original zyn author) actually knew what he was doing, and every time I've tried to vary things in that area I've stuffed it up! I think this little item might also account for comments along the way that instrument loading in general was taking longer than it used to. And so there's ... 0.059-pre2 switch fftw planner flag from FFTW_MEASURE back to FFTW_ESTIMATE, enabling plinky-plank to load in realistic time. Let me know if it works for you, <http://www.graggrag.com/yoshimi/yoshimi-0.059-pre2.tar.bz2> cheers, Cal

I did go looking at the fltk source, but to honest I quickly lost interest. One day I'd like to figure out what's going on there, but I wouldn't dare promise how fast or slow that might happen. cheers.
