Topic: performance problems rendering midi file
i have a midi file that i recorded a while ago that i would like to render using a recently posted FXP (Qexl's Truth Serum, which sounds very cool). this midi file makes substantial demands: lots of pedal, high polyphony, bass clusters struck loudly and held for a long time, etc. (it's kind of an experimental sonic piece.)
for the life of me, i can't figure out how to get Pianoteq to render this file to a flac without getting dreaded red lines in the performance meter. i've made sure my CPUs are running in performance mode, i've increased the latency to the bottom of the menu, i've tried tweaking the highest allowable polyphony, but i still get cracks. note that i'm not trying to produce anything in real time, i just want Pianoteq to take its time, do whatever computations it needs to do, and produce output. if it took 24 hrs to do it i could live with that. is there something else i can try to get the computation to work? am i missing something? or are there hardware limitations that can't be overcome even when running time is not a significant factor?
my computer is running linux and the CPUs are Intel Core i7-7500U CPU @ 2.70GHz. it seems to me this should be enough power to do the job. i often do very demanding computations on this box with no problem. but i guess i could be underestimating what goes into the model.
