I am happy
you are considering the non-immediate-overdub feature as a
"must".
I also agree with Matthias when he says that it
absolutely impossible to think to improvvise with such a
limitation.
**
well, just for the record, there are people who improvise without this sort of
thing all the time. you may not be able to do it and i may well be a desirable
trait, but it can be done - - and i'll probably do it three or four times in
the next week and a half.
