Paolo helps:

So you choose any time into which delay you want to load and can change its
"seed" number and Feedback while playing and stay synced between all delay
lines, if you want. Yes?
The Notebook and the price of the program is a drawback for whom uses it
for this only. Ofcourse you record and organized the instruments too,
handy.

Those little MIDI players could be capable of a little more: They could
read a program from the disc and execute it while recording MIDI. (they
don't do that, do they?)

But, back to Paolo:

Random seams interesting. Could be done in a audio looper, too. But then
again, if the machine does not know where notes start and stop, random will
chop all up. We will have to analyze the sound to improve.
MIDI is fascinating for this kind of creativity.

What is this problem? Do all sequencers have it?

So there is a way to imitate the FeedBack of a delay on Max? Each
repetition gets softer? I will have to study Max more.
But in a sequencer it is not possible, is it?

Well, for my music, I am not interested in using MIDI. It reduces
expression too much for my taste. Probably even ZIPI would have been little
intuitive.
But:
** I think it would be great to use similar tools and codes in audio- and
MIDI loops so we can play together, transfer, synchronize easily. **
