I have made an ambient synth high has a release set, a delay and reverb with 6 voice it's at 23-26% and with 1 voice it's about 22-23% CPU, do you think this is two high or is that ok for an ambient synth do you think? It's definately the effects side of things which is causing the high CPU so my question is, is there actually anything i the user can do to make the CPU better with effects set with high values like long reverbs ect? I myself think this is too high but i have had higher before with other ambient stuff. Devs could you help with this please (if your not too busy again that is) 😀

What's the cpu with all FX switched off? I reckon the culprit is probably the reverb.. Even though it is quite efficient, it still takes lot of cpu, that's the nature of reverbs unfortunately..
Try removing one channel from the reverb, ie the left or the right, and compare the sound-quality/cpu trade-off.. Other than that, I'd just add a switch and leave it up to the user if they want to use the reverb or not...

Hmm it's actually quite high without them 15-16%, im guessing its also to do with the release if lowered it goes to 6-11% CPU. It seems that whenever i get experimental with synths CPU can get crazy, with effects its much lower for some reason, it would be great to be able to make loads of weird audio making devices in SM but coming back to synth dev from effect dev it seems the problems are still there 🙁

do you have a selector for max number of voices?
the MIDI to Poly default is 32 voices

Its set to 1 currently when playing note CPU is about 22%

how many OSCs anf filters are active?
also which CPU is yours?
Tom7777 ·
2 oscs no filter, the CPU is from SMs readout

Seems quite high to me... Are you using any third party modules? Is this with the delay on?

No and no, its just a customized synth, im waiting for one of the devs to help really that all i can do i guess as i don't want to share the synth at the moment, they didn't help the last few times but im hoping they will this time 🙂

What standard modules are you using (without giving too much away..) The cpu seems too high for just 2 oscs.. Have you tried using the cpu profiler I posted on the wiki, this can be very useful in isolating a specific cpu problem in a schematic, if you're not sure how to use it I can give an explanation..
You should try to identify where the cpu excess is coming from first rather than asking the devs to test a whole instrument. If everbody was relying on them to do this SM would go nowhere 😉.. You can get help from folk here in the comunity without giving away to much of what you are doing, by asking people to beta test part of your synth as a vsti eg 'how does this osc combo sound...' I'm sure someone would be able to tell where you are getting the problems from.. Everything I've released here has benefitted from the comments and suggestions of everbody, that's what great about SM 😀

Yeah im not sure how to use it, also even if i did find the cause lets say it's the osc what do i do then, replace the osc which is the main part of the synth? I think it must be a bad module combo or something as i have run into similar problems lots of times before and is one of the main reasons why i normally just make effects. Sure i can make synths that are low on CPU (high level modules 3 osc 1 filter ect) but i don't like doing this, i like to experiment and shape the sound which is what i have done with this synth but it seems that SM can't do this without getting high CPU each time i try anything non standard. I have used reaktor and it's great for making experimental synths which is what i would love to do in SM but sadly its not up to the challenge yet. The whole point of the program is to be able to build stuff right so im my opinion bad module combos should be high on the bugs list i think. Sure you could give me a workaround im guessing but if the problems not directly sorted out it will just remain for future problems so i think problems like mine should be thought of as just as serious as any other bugs.

Hi Dan,
if you want to send me a part of your schematic you may stay sure that I
wouldn't spread it, you know I'm in the business too, <grin>
