Using The OP-1 As A Groovebox

I wanted to try my hand at creating something using samples, but without using any of the sequencers or tape on the OP-1. I found if you trim the samples so that the downbeats are all on the white keys and the upbeats are all on the black keys, it makes it a lot easier to keep track of where you are in the measure and have more freedom while messing around.
