I've got a show coming up this summer that is probably going to require me to trigger a few samples (something that's new to me). I'm doing some research looking for a pedal that can be loaded with samples that can be triggered on the fly. They need to be repeatable, in time. I'm guessing the Boss RC2 or RC3 can do this. Anyone know for sure if that's correct? Any other options I should look at? Cheaper is better since this is specifically for one show and will likely not remain as part of my rig.
