The same way as I have learned most things in Cubase… by trial and error
A quick follow up question, if I could please: I notice that the toggle of Musical Mode/Linear > in the Pool > seems to be the only thing that determines whether the audio “follows” the Tempo Track - whether it is toggled on or off > in the Inspector > has NO effect on whether it plays back in Musical mode vs linear. I’ve tried that at least a dozen times, with different audio clips … can that really be right? … or am I making a > > here?
This is often a source of confusion…
Musical Mode (in the Audio Pool, or in the waveform editor) does the job I described earlier. This is something completely different from Musical vs Linear Timebase, as seen in the Track Inspector, which determines merely how Events (Audio events, Audio Parts, MIDI Parts, Markers) begin, in relation to the timeline. (N.B. an audio event is the position at which the clip begins).Once the audio event has begun, according to the Timebase mode, the actual speed at which it plays depends only on Musical Mode in the Pool/waveform editor.
Musical vs Linear Timebase (in the Inspector, or track list)…
Linear Timebase… the event will always start at the same time position (e.g. 1 mn:30 sec), no matter how you change the tempo… so, for example, if the event was originally at bar # 46 with the tempo at 120 BPM (which does indeed occur at 1 mn:30 sec ), and then you change the tempo to 60 BPM, the event would still occur at 1 mn:30 sec (but which would now be only bar #23, beat #3… Bar #46 would now be arriving at 3 mn:0 sec).
If you switched the Inspector to Musical Timebase before changing the tempo, upon changing the tempo, the event would maintain its musical position, at bar #46 (which, as we have just seen now plays at 3 mn:0 sec).
So it is perfectly possible to have the Track in Linear Timebase, while the audio clip itself is in Musical Mode (in the Pool)… or vice versa.
(as you have now observed, there are no “quick” follow-up questions! )
