Sean McColgan via his site Dystopian Disco has created a rather nifty Max for Live editor. Volca FM Editor does what its name suggests… enables you to control and automate the volca FM inside Ableton Live 9.
Specifically, Korg volca fm Editor gives you control of the modulation matrix and the ability to generate new sounds on the fly (from deep bass, to otherworldly sci-fi efx) with an in-built randomization feature.
The device is currently in BETA, so you can download it for free via his website and help make it better by providing feedback.
Listen to some of the randomisation features:
