|Author||Topic: Hey Jason: Sonic and CPU load|
Posted: 22nd July 2002 07:43
I’ve been playing around with some of my VSTs and have noticed something, maybe everyone else already knows.
Some VSTs are CPU heavy, others are RAM heavy, and some a bit of both.
Sampletank is inbetween, not real heavy on either.
VG is heavy on Ram and light on CPU
Battery is heavier on Ram, but lighter on CPU
M-tron is now very light on CPU and I’m not sure about Ram.
Ok, so here is my request. It would be great if one could pick between two modes in Sampletank. One would be RAM heavy, the other CPU heavy.
I have Ram to spare, but my CPU is rather average. It would be great to switch ST into eating up my RAM and leaving my CPU for other things.
If it could be only one way or the other, of course I would take the RAM heavy.....
I am sure it is more complicated and all, so some light shedding would be in order.....

Jason are you there?

Sampletank itself is not very CPU heavy at all. It is the realtime efx that can kinda nail you CPU. Reverbs tend to be the worst. Try loading a bunch of sounds, then cut off all the efx on all the midi channels.
Then watch your CPU get really low.

ST can be CPU heavy when playing a piano patch and holding the sustain pedal down. I also find it odd that if I hold the sustain pedal down, with polyphony set to 16 then hit the same note 16 times you'll overload the polyphony, not to mention seriously up the CPU even though it's only one note (albiet hit repeatedly). Would there be any kind of workaround for this in the future Jason? Perhaps a sort of "smart polyphony" manager that would cut down on the CPU/polyphony load, when one note is repeated with the sustain pedal down?

Ditto to what Funkybot said along except when polyphony is exceeded any application using ST crashes.
jwnc is dead on about the effects, turning off reverb on 4 chanels on my computer frees up 10 - 20% CPU.

Jason has a good point. Well how about a quality button for the effects?
I just remebered I could run ST in a quanitity mode instead of quality, can't I?
This is what I want, to be able to switch from High to medium quality on ST gui. That way I can run ST all I want and then switch to high quality and start dumping tracks to audio when I mix down.
Also, A VERY GOOD POINT about the sustain. If ST had a smart sustain feature, it woul solve a great deal of my problems.
