howdy,

ok so i got this rolls midibuddy to control my 404sx externally, only thing is that i can't figure out how to trigger the samples. the only thing i can trigger is the last pattern i played, even when the channels aren't the same...any help?

You can't do it with the Rolls because it doesn't send Midi Notes, only CC messages. You've got to get the Behringer FCB1010 isntead.
