samplers loopers and midi

["michael hayungs" <mhayungs@hotmail.com>]

I don't know if this has already been discussed but for the longest time 
I've been in search for a looping/sampler set-up similar to the new Boss 
RC-50 but slightly different. Basically i'd like to take a sampler device 
similar to the Roland SP-404 (midi syncable) and trigger samples on it 
from 
a midi foot pedal, like that Behringer one but smaller. Does anyone know 
of 
a more compact midi foot pedal that sends midi note on/off signals? 
Basically I'd like to designate one pedal to one sample pad on the SP-404 
or 
similar unit. Sounds like the RC-50 might be the easiest option, anyone 
know 
when it's coming out in the US?
