Topic: DDJ-FLX10 - Stems EQ per Channel Question
So I finally decided to upgrade to the DDJ-FLX10 (will be coming in soon), and I was just going through the functionality on the DDJ-FLX10 hardware manual page

I noticed that, for the Mixer section, there is a Shift + PFL function to switch the channel to a stem isolator mode (as marked on the faceplate), but the manual doesn't describe it, and there isn't a SHIFT_PFL key that I can see in the list of key mappings for the controller.

Is there a reason that this is missing, given the Rane Four/Rane Performer has this functionality?
I noticed that the Rane Four/Rane Performer do not have a master cue (so it's easier to know that it's a deck that is being cued) - is this the reason? Can it be worked around?
Is it missing at all (am I misunderstanding the manual/current mappings)?

It's not that I absolutely need the functionality, it just seems a bit odd that it is missing and it is possible with other controllers.

Will check and let you know.

My notes say "SHIFT_PFL is hardware, should not be mapped" but cant recal why.
 
OK, cant find anything that works in a "hardware" way, the only thing is that if you assign to SHIFT_LED_PFL to get the status the ON/OFF is On and Blinking instead of Off/On. So you get this annoying PFL led blinking every time you press SHIFT.

Anyways, perhaps the FLX10 was initally mapped when the eq_mode +1 deck was not yet implemented.
So try the following and see if it works as expected..
SHIFT_PFL : eq_mode +1 deck
SHIFT_LED_PFL : not eq_mode frequency deck
 
I got used to using the stems with buttons because the “eq_mode +1 ‘deck’” option didn't exist at the time. Later, I tried mapping the function once it became available, but it didn't work as it should.
It works in skins—it switches the deck’s EQ to stems or frequency mode—but when I use the FLX10, it switches all channels to stems mode. However, the moment I move a knob, they revert to Frequency mode, so I have to manually go to the stems menu and select ModernEQ, and then all the knobs work.
But let’s say I want channel 3 to be in Frequency mode again—no matter what I do or where I select it, all the knobs just revert to ModernEQ when I move them.

I tried several times, but since I’m not good at mappings, I gave up and just use the dedicated buttons. 😅
 
This is the mapping of SHIFT_PFL on the Rane Performer:

setting 'stemsRealtimeSeparation' 'fully disabled' ? nothing : setting_setsession 'eqModeDual' 'None' & eq_mode +1 deck


And the mapping for SHIFT_LED_PFL on the the Rane Performer:

setting 'stemsRealtimeSeparation' 'fully disabled' ? off : setting 'eqModeDual' 'None' ? setting 'eqMode' 'Frequency' ? off : blink : off


It seems that at the very least, it also includes an extra check for if stemsRealtimeSeparation is enabled to allow the change to be done.
I don't have the controller yet to try @djdad's mappings, but it didn't seem to me like too much work to try to do, given the Rane Performer/Four now do it (hence I asked).
