Lets you control your drum machine or any other TRIGGERED device by MIDI. Supports up to 8 instruments each with velocity control.The No LED PCB Assembly requires you to supply your own panel mount LEDs for use as an external status indicator. The Onboard LED PCB Assembly assumes that programming (LEARN) is only required once or very rarely so external LEDs are not required thus saving panel space. A pre-programmed ATMEGA8 is included in the kit.
