Now I am confused. I was not aware the JM was able to play its various
loops simultaneously. And its your proposual for this modification that
iniciates this mail... ?
Or: what would be the difference between a multitrack looper and having
several simultaneous loops?

Hmm, you do not use multiple loops (neither do I), but would we use
multiple tracks?

The Plex is not able to play several loops simultaneously, so far.
The idea with scrolling through loops is common to all units and ideas.
You would not need to operate several loops as one?
To "pre-operate" them with the "phrased" (JM) or "quantized" (Plex)
functions might help, but in my case would not resolve, because I rarely
play in respect to loop-end.

I see that a extended use of multiple tracks could make UNDO and Multiply
rather useless (having only 3-5 parallel loops, I would still want them!).
But then, the various loops have to be of different length and synced,
which corresponds somehow to the Next-Insert (TimeCopy) function of the
For the operation of several loops, would it become complicated?

Then, there was MiqSk8's dream:

Yes, I think display becomes very important in this context. Thats why I
thought we should do it in a computer right away...
Do you think a LCD would do it?
Or did I get your wrong... you want to send this information by MIDI from
the looper to where?
Would it make sense to have a looper hardware that takes a computer to
control it?

Sounds good, all kinds of interdependent cues.
For me it would be like a mixing desk with pan for each loop and at leas
one Aux send, because the percussion loops I have done lately need
different reverb and positioning for each instrument.
But it also takes a system that my friend percussionist is able to 

We will end up getting there!
