Using Samplers live?

Hey,

I was wondering if it is possible to loop yourself live with a sampler? I am

currently using the Boss RC-20 but this is limited to only one playing

channel and it can't be controlled by MIDI.

So I was wondering if I could run a sampler like the AKAI Z8 with a timecode

and press record and it records automatically exactly on the beat and if I

press stop shortly before it should stop, it starts looping right away on

the beat - so there are no timing issues.

If this is not possible are there ways to be able to have several loops

running at the same time and control them with a mixer?

Best regards,
