Project with High CPU

[bendurso]

I have a project with two wavetable processors, a waveform generator, several effects, and a convolution reverb.

The CPU is around 40% with everything activated. Turning off the convolution reverb doesn't change much. By disabling both wavetables the CPU drops to 5/10%. The problem seems to be the wavetables.

But when I create another empty project, and simulate something similar to the original project (2 wavetables, 1 waveform, effects and conv reverb), the CPU is around 10% or 15%. So I don't know why the CPU consumption of the original project is so high. Any ideas?

@bendurso Can you export it to VST and try it in a DAW?

[bendurso]

@aaronventure In the exported plugin the CPU usage is also 40%. (The DAW shows the same CPU usage). I have a Mac Mini M2

[aaronventure]

@bendurso Are you doing some crazy stuff with scripting for the wavetables?

[bendurso]

@aaronventure Nope, only wavetable selectors, and next and prev buttons.

I haven't played with wavetables yet, but maybe you need to use a fixed block audio buffer?

@Dan-Korneff It could be. How do I use that with the wavetable processor? Should I use it as an FX at the end of the chain? Because there is no wavetable node to insert it into the buffer node.

@bendurso If it's not available in SNEX, then I think you're outta luck :/

I just discovered the problem. The excess CPU was due to putting the wavetable synthesisers inside a synthesiser group. I placed them outside the group and the CPU usage returned to normal. I don't know why but anyway I wasn't using the synth group functions.

Actually I created another synth group and now it works ok. So I don't know what was going on with the old synth group.

@bendurso Perhaps exploring the XML would shed light on any discrepancies between the two groups...
