I’ve created a patch that changes the output MIDI channel of five tracks at once upon receipt of a control message, and it makes my CPU usage jump about %9 or so and a burst of digital clicks, even if those tracks aren’t outputting anything at the time. Any way around this? (I’ll try spacing the five changes, but that’s sub-optimal and this seems like it shouldn’t be happening anyway). Thoughts?
Yes, it does, even changing a single track at a time.
I tried it with an empty set – one audio source, one MIDI track – no problem. But if I run it up to 64 MIDI tracks (that’s not the actual threshold, but when I got tired of duplicating tracks), it starts to occur intermittently. Nowhere to the same degree as my main set, which has rather a lot more going on, but it’s clearly the same thing.
The volume of the noise is dependent on the volume of my output – if I do the same thing with the source track pulled down, I don’t hear it. It’s not the source itself, or occurring on the input side – I recorded a loop in and it’s still occurring in the same way playing the loop rather than the input audio. I changed to my laptop’s built-in speakers, and it switched from occurring intermittently to occurring without fail. Then I deleted half the MIDI tracks, and it disappeared.
CPU usage with one audio clip playing and 64 empty midi tracks is 2%.
I appreciate your efforts to help but I have a feeling we’ve hit a dead end here…
