cpu killers

October 21, 2013 | 9:38 am

I have this bog patch I have been working on for some time and I am about to finish it all up. But I have a sub-patche that is sucking up cpu like mad. One is a 6 voice harmonizer based off gizmo~. When i turn on this system it shoots up about 15%. I placed a gate~ in the audio path before the pfft~ input but that really didn’t do much. Is there a way to turn off that processing while it is not being used?

mute~ ?

That doesn’t do it either.

look at thispoly~. it has a mute function that shuts off all DSP inside the pfft~

I assume the gizmo~ is in a pfft~?
Pfft~ takes up a large amount of resources, if you have one in a 6 voice poly~ then this will be 6-fold.

Maybe experiment with different FFT sizes and overlaps,
or put 6 gizmo’s into one pfft~ to save on analysing/resynthesizing 6 times.

Or look into creating a harmoniser that is cheaper on resources using delay lines.

thispoly~ didn’t seem to do anything but I’ll investigate more. I probably should look at redesigning. thanks for your help.
