Hm... not while playing, but on the fly... I maybe do not understand "on
the fly".

And why would you change channel? You mean track, maybe?

I can imagine to have a one bar delay on one track and a 4 bar on the other
and while playing (or just on the fly?) I can change the track and add to
the one that corresponds to the actual "musical velocity" I am looking for.

And the delay keeps adding notes to the sequencer while recording?
Or do you apply the same delay again for "mixing"?

Olivier has feedback! And how much delay time, Olivier?

Very much so. Strange that Peter Gotcher, the creator of the enterprise,
said in an interview years ago, that he is interested in looping. I wrote
him twice, no answer.

aha! very nice! Why let your creations be covered by virtual dust?

And the sequencer delay has this problem resolved? Olivier?

They probably sold 10 or even 100 times more sequencers than Max. The real
thing would be with digidesign and audio sequencers like digital performer
or logic audio. But to get there we could discover a lot with Max.

So the Max looper should be feasable. Who... ?

Maybe we are breeding on a product? Dont worry, I am constantely, even when
I make my Maracuja/Banana or Carambola/Umbu/Banana jam (mmmm...) Anyone
wants to import exotic natural jam from Brasil? What? Off topic? Ever
looped with a spoon in a pan? Jam session!

Sorry for my mountain of questions.
