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?
