Access unique plugin instance id?

[parkellipsen]

By the way, apart from the problems with Final Cut mentioned above, Ableton Live (at least in combination with AU) has a quirk that makes the ID thing more complicated, see my post here:

Quirky behaviour when changing blocksize [Ableton | AU]

Here’s another host quirk, for ableton this time: It seems like Ableton (tested with 9 and 10) creates new instances of AU plugins when the blocksize is changed and loads the Settings by copying over the memory block. When the samplerate is changed, the same instance is kept and prepareToPlay() called with the new samplerate. Neither does that happen with VST in Ableton, nor with AU in Reaper, as far as i am concerned. Has anybody else observed this ? I assume there’s no way to influence that…

Not sure how that affects your use case, but it surely does affect mine …
