Nice suggestions, thank you.
You seem to think rather Quantized. We want the liberty to press any 
function at any time and it should do it immediately (although we 
also offer quantized).

So in Overdub the function would be what we have now?
In Play it would for example go back to before the last Overdub was 
started?
The long press function cannot be totally different because we start 
the action before the long time is reached.

I dont quite understand... trim?

due to the delay structure we use, all overdubed versions follow each 
other in memory. So what you suggest is that we keep A separately 
while running through the rest of the memory, so A can be called back.
This somehow fits to he new UNDO function you suggest above. We could 
save a previous version of the loop (not necessarily the very first 
nor before the last function) and come back to it later.
Then again, thats what NextLoop is good for:
Work with LoopCopy=Snd or NextMultiply and 2 loops. Thus you can also Redo.

To fascilitate this, I could make longUndo (if MoreLoops >1) switch 
to the previous loop and erase the next, so next time you press Next, 
LoopCopy=Snd causes a new copy.
