Impulse Tuner – Max for Live device


The “Impulse Tuner” lets you change the pitch of incoming MIDI notes to the required pitches for triggering Abletons Impulse. Those pitches consists of a C major scale starting from C3 (C3, D3, E3, F3, G3, A3, B3 + C4). As those pitches are fixed to trigger the 8 fields of the Impulse you can’t change the outgoing pitches in this Max for Live device but change the note pitches of incoming midi notes real quick and save this as a preset in your User Library.
