It seems to me (and I think it’s a great idea) that some, maybe even most, of the functionality you’re looking for with the “ReFace” units and the vortex, could be provided by a “driver” - not a driver in the normal sense of the word, but a Zynthian driver:

Keep in mind that this is a new feature for Zynthian, so it is not available in the current ‘stable’ release. It will be in ‘Oram’, which is available, but in a non-‘stage ready’ version - meaning it’s still being worked on.
