REKORDBOX stems separation hack

Been struggling a lot with REKORDBOX and Streamdeck, as REKORDBOX ON/OFF features require toggles (CC value of 127 followed by CC value of 0), to toggle, so all modes I've tried of regular midi cc fails to get proper state.
Ended up doing a very simple script:

[(press){cc:1,32,127}{cc:1,32,0}]
[(cc:1,33,127){state:1}]
[(cc:1,33,0){state:0}]

on Streamdeck side, and this on REKORDBOX side:


(screenshot seems to be vut on the right, it says MIDI OUT = B021. 020 is 32 in hexadecimal format, 021 is 33)

Streamdeck is sending switch message on CC32, and receiving from REKORDBOX current value on CC33.

This way, state of the button is fully handled by midi messages received from REKORDBOX, allowing for proper state display, whereas button press will always send the push and release on CC, triggering the toggle on RB side.

Dunno, maybe it's doable in an easier way, but this one works, and you can use the same hack to control anything else not present on your DDJ (like lowcut of the reverb, freeze on an echo, ...)

Hope that helps someone ;-)

Very good ! I hope i will be able to do the same thing with VirtualDJ !
