Insane CPU usage

[kv331]

Please correct if i am wrong, but while ago, you Bulent, told us that sm is only sse..? How about adding support to newest ss3&4? I think those would reduce cpu usage or something...

Well, SSE is used in some parts of the code, not entirely. For recursive IIR filters (= all filters in SM are IIR filters), vectorization is not an option, but for FIR filters (like the ones I used for resampling single cycle waveforms), they help a lot (FIR filters in SM are already taking advantage of vectorization)

Ah 6 notes.. why you dont say this^^

as comparison, i have intel I-Core 7 -920 on 32 bit, and there same sound eats on 4-6 notes ~12% cpu

I did. When you play 6 notes, and then quickly switch to 6 different notes, SM *states* 12 voices in use

I'm curious how you manage only 12% cpu though. That seems much lower.

Try increasing the "engine buffer size" to LARGE.

kv331,

Sorry I did not respond, but I tried the lowing the quality, but it only knocks it down by about 4% which just is not enough to run more than 1-2 instances. Also it virtually makes running it while running a handful of other Synths nearly impossible, hehe.

I understand that unison heavy patches will kill my machine, but dang 40% CPU, ouch! hehe

I also hate to convert to WAV so early in the inspiration process just in case I need to tweak the Filter/ADSR or others a bit to allow other things and itself the right space.

Cool synth though and I cannot wait for that Easy Editor page!!!
