I’ve had some cases where a sound needs to retain its pitch but play a shorter cut of it when a parameter changes. I did this by raising the pitch of the event master (timeline goes faster), then pitching down the multi-sound. Result: pitch stays the same, but the playback is shorter. Or, you can make it longer by doing the opposite; or trigger more frequently with a loop, you get the idea. In any case, there are two pitch changes (master vs content) that cancel each other out.
Caveat: pitching sounds up a lot leads to longer buffer reads = expensive.
So I’d like to know: what happens to buffer reads if the whole event pitches up, but all multi-sounds inside it pitch down? The pitch doesn’t change, but does the scheduler still need to do a longer buffer read “just in case”, thus making the event more expensive to play back?
