Hey, running into something weird with rekordbox and not sure if it’s a bug or just how it works.
Stems themselves are fine (I can mute vocals/drums/instruments), but when I try to use Stem FX, the INST and VOCAL buttons can’t be activated at all.
They’re not just turned off — they never go into the active state. Normally they light up when enabled and go fully grey when disabled, but in this case they just stay in that dim state and don’t respond to any input (mouse or keyboard).
For some reason only DRUMS works and can be activated normally.
Weird part is this works perfectly on FLX4, XDJ-RR, and even just using Mac internal output, but as soon as I switch to DJM-A9 + CDJ-3000x it breaks.
If anyone here is running a DJM-A9 + CDJ-3000x setup, could you try this and let me know if you can activate VOCAL / INST in Stem FX?
Trying to figure out if this is just my setup or something with A9/external mixer mode in general.
