Re: Samplers as loopers?

Not mine, and I believe not most. That's why I recently bought a JamMan.

Good idea!

Once again, my old sampler (AKAI S612) had an overdub function which
allowed you to
press a button and simultaneously hear/record with the existing sample.
My new sampler
(ASR-10) works _exactly_ as you've explained. Record samples and play
them together.
You can do other nifty tricks like splice sections of samples together,
invert samples,
merge samples, even direct the machine to play individual samples (those
constituting a
single waveform) in specific or random orders.

Actually, the new sampler (ASR10) seeks to automate a number of functions
which the
manufacturer designed under the assumption that musicians would use it to
make standard
bourgeois music a la any Late Night Talk Show Band. In other words it is
not as
"open-ended" as I would like it to be.

In a sense, yes. Using the function MODULATE LOOP-POSITION, you could
loop sections of
a piece (e.g., one-half minute starting at zero ending at 100) as many
times as you like
and then move on to another section with overlap of the first (e.g.,
one-half minute
starting at 25 and ending at 125). This can be done in real time using a
wheel to
control the position of the loop. The only thing is that the start- and
end-points of
the modulated loop would remain fixed. This is why I want to use some
type of slider
that will augment or diminish the loop unit. I'm actually trying to
devise a way to do
this on my keyboard. I will keep you posted.
