MA_House 14 & 15 respond to increasing numbers of held/sustained key/note inputs by adding more drums to their patterns. They don't seem to have the "note stealing" issues of melodic arps, instead the patterns gain drums and complexity as the held notes increase.
This is quite wonderful, but I know nothing about it, until today.
How many more of the drum arpeggios operate in this fashion, and is there a chart of the note inputs and what they change about the drum pattern?
I'm nothing but optimistic, that somewhere in the world between KAOSS and earlier Korg ownership, some spreadsheets layout how these things work and still reside on a server somewhere in the south of Tokyo 😉
