Teenage Engineering Crank

Mount the crank accessory on OP-1's blue knob and press shift + rec. Your OP-1 is now in "hand-crank-recording mode". Use the crank to create some real vintage old skool recordings. It's also possible to crank counter clockwise, to record backwards. All in realtime. The crank also lets you use the endless sequencer as a hand cranked music box! Just enter the notes and crank the crank! The crank LFO lets you crank any parameter. Included in the set is 4 color knobs in OP-1 colors.
