Love the monotron, its a part of my live setup
usually run it through my Korg KP3 fx unit and put some modulation and delays on it for crazy extra tweaks
And yeah its great for the techies out there to mod and expand

Ableton is my main writing and mixing tool, which I control with an Akai APC40, Korg NanoPad, and Novation ReMote 25SL
Also got a Korg Kaoss Pad Quad and handheld Kaossilator for fucking around live over my main tracks
