16-Step MIDI sequencer
The EMW MIDI STEP SEQUENCER module is a very straight forward 16-step MIDI sequencer that allows you to create complete pattern-based sequences very quickly. It has features such as octave control, reset, and hold inputs as well as a "Beat 1" trigger input that allows it to interface with other modules in many different ways. A pulse signal from a LFO patched into the to the "+1 OCT" input adds very interesting variations into the sequence.
