Reply to Midifighter As a SYNTH!

so i like the idea of playing the midifighter as a synth. as you all know it spits out basic midi, and im using it to play notes in different synthesizers in Ableton live.

but my problem is that i cant change octaves without touching a keyboard... ick... i have an APC40 and the korg Nano series, if that helps a problem solution.

TL:DR, i need a way to switch octaves in a synthesizer and play my midifighter as the notes in the Synth
