I usually sample the inputs, I haven’t tested main/cue/tracks for volume leveling. I’ve resampled but haven’t used the transition trick so volume leveling hasn’t come up…
In case it helps:
For inputs, Mixer dir: 127, track level: 127, amp vol: 0, Attribute Gain: +12
Will get you the same volume flex sample playback as the mixer dir signal regardless of master track volume and mixer main volume…
Looking at these settings it looks like you just need mixer dir and flex playback to be the same number when sampling inputs, however by setting them both to 127, master track level 127, and raising the mains to +18/19, the outgoing signal from OT is then the same level as the signal entering the inputs, which is very helpful for live sampling when using multiple monitoring methods…
