Hi
I’m having a problem with VCA channels: When I switch on/off the tempo track or when I do changes to the tempo, channels assigned to a VCA track change their volume.
Repro:
Create new project
Create some audio/instrument tracks, put audio/midi data on the tracks
Assign the tracks to an VCA fader
Write automation with the VCA fader
Switch on the tempo track
=> The tracks assigned to the VCA fader jump to max volume.
I did a short video which documents the problem: - YouTube
I tested it with audio tracks + a VST instrument (for the midi). I don’t think it is possible to put a plain midi track into a VCA group (I couldn’t at least).
It doesn’t matter what kind of tracks, I tried with just an Instrument track. I attached my test project with an Halion SE track, maybe you can try with that project?
If I write VCA-Automation in this project, then position the playhead in the area where automation data is written and then turn on the tempo track, the automated track’s volume jumps in strange ways. I just realized that depending on what level the fader is when you turn on/off the tempo track, it moves to max volume or unity. And sometimes it decreases volume in small steps each time I turn on/off the tempo track - see the video here for that behaviour.
Sorry for not being clear enough: As you can see in the video, I did my test with random midi data on the instrument track. I haven’t checked if it also occurs with just an empty track. I also tried with audio tracks with audio events on it. However, the problem seems to be independent from the kind of track as it happens with instrument and audio tracks.
Thanks for reproducing the bug. Yes, it seems important that the playhead is in the middle of some VCA automation. I also have the problem that moving tempo markers in the tempo track destroys the sync between VCA master and slaves. I didn’t have the time to reproduce it consitently, will try later.
Also, when you write “audio/instrument track”, what does that mean? Is it sufficient to use just an audio track or does ‘an instrument’ have to be involved somehow?
