wow, this all sounds amazing 
reading about the CV utility plugin, may i hint you to an idea for a MIDI plugin generating programm change messages i had in another thread? the thread is about improving control over snapshots, by adding a way to group snapshots by songs. snapshots can be loaded by MIDI PC messages (so you should be able to jump to each snapshot that is the first in a song), but as far as i am aware there currently is no plugin to do it within the dwarf (only via external MIDI devices). perhaps this sounds interesting enough for you to consider it for a future project
