Our RK-005 or RK-006 will program the RK-002 as well as other USB MIDI interfaces, as long as they support MIDI power and MIDI System Exclusive messages.

Cloud DUYs : A new (W.I.P.) feature on RK002 DUY Portal:
- Can be edited and compiled within the DUY portal, no Arduino IDE needed anymore.
- They're accessible from your account page and can be published and shared as quick DUY binaries.

The blue buttons indicate compiled DUY's, the green buttons are related to the online source code/editor.
