When you’re playing a piece of music and you need a simple ‘backbeat’ this circuit will come to the rescue.The MIDI Step sequencer drives a synthesizer or a (music) program on the PC via MIDI. A maximum of 16 notes can have their MIDI properties configured via 20 keys; 16 of them for the notes and four for loading, saving, mode-selection and start/stop. With this device it becomes child’s play to create background rhythms or repeating melodies, for example.
