CPU usage with VSTs

Help, Support & Bugs
1

I open RENOISE with a song with lots of VSTs and without hitting play CPU usage goes up to ~40%. After sending midi off to all plugins usage goes down to 2% or so. Is this normal? I’m on 3.2.1b1 and it also happens with 3.2.1 stable in Linux.

I had similar problem and I think what happens is when you save a song make sure no audio is playing.Hit the stop button twise before saving.Also the problem might be some 32bit plugins don’t behave good with Renoise 64 bit.

Thanks, I’ll try this. I only use 64bit plugins (Repro-1 is causing this)

Not the case. I think it has something to do with Repro-1. When I load the song there’s some bass already playing in Repro-1 which is not audible. When I send note off it stops:

I didn’t find the problem. Don’t know if it is normal for Repro … I asked at KVR.

Is multicore in Repro activated?

There’s also coming sound of it when you start the project?

I don’t see it. Does Repro-1 have multicore support?

Ups, I overread you do not use Repro-5. Then please go on.

Some times yes.I think is mostly the plugins fault not Renoise

It was because of the activated drone mode in the Repro-1 settings. Urs replied at kvr.
CPU usage is not related, that’s just normal I guess.
