This Max for Live device lets you quickly set up a sequence of different MIDI note pitches in Ableton Live. This can be handy to play a melody or bass line with just one triggered by only on MIDI note.
You need some programming/support in setting up an Ableton Live set?
I can help you to find a set-up which works for your approach.
