Transistor Rhythms

Includes every sound from the most sought-after TR drum machines, with detailed circuit-models of the 808, 606, 909, 707, 727, and even modified versions. Each machine is a detailed, down-to-the-circuit-model that sounds and behaves exactly like the original.

Fast, Fluid & Fun

You can program on the 16 TR-REC buttons or use the velocity-sensitive performance pad to play live, or record into the sequencer. Get experimental with unusual polyrhythms and complex meters by adjusting the length or "last step" of each drum part.

ACB Meets Samples

Pull from the extensive collection of preset samples, or import your own mono or stereo sounds using the SD card slot. Like the TR sounds, you can deeply manipulate samples with immediate hands-on control.
