I've got 12 HP left. And I'm treating myself for Christmas another module. However I don't know what. I'm not really missing any function. My rack goes together with a Minibrute 2s for sequencing.
The 12 HP doesn't need to be filled completely. Budget i haven't determined.
On a longer term I want to get a better mixing for the four sound sources. Not sure if this is in the box or outside of it. I miss some basic EQ and easy volume control.
