Real Time Sampler Question?

[kamlapati.khalsa@philips.com]

Does anyone know :

Is there any sampler out there that will play a loop while sampling? That 
will play back a sequence, be it drum sounds or whatever, while sampling a 
new sound, and then let you add it to the sequence? Of course my EDP does 
it but my SP-808 does not and I 
wish I could find something that does!  Does anyone know about the high 
end samplers like the Akai, E-mu, or Yamaha?

Thanks,
K
