Topic: Stem fx pads do not work with DJM-V10 connected
I have this pad fx for echo out:

padfx "echo out" "Feedback:75%" "Length:0.5bt" "Reverb:24%" "stemfx:vocal"


When i am just using my laptop speakers, it works as expected. When I use my DJM V10 for audio, any stem fx completely mutes the entire track.

Thank you

I have tried using the default audio setup but it doesn't change anything.

When stemfx are used, does the entire audio chain go to the fxsend channel, or just the fxsend? (I don't think that's the issue in this case- even when all channels are set to USB input, none of them get audio).
 
Plus, i have had this working with the DJM S11 (which also has channels for send/return). The non-effected stems and the stem fx still route through the deck's channel, not to a different usb channel. Maybe something changed with an update, i'll pull out my S11 and try to reproduce there.
 
S11 works with the same version of VDJ so I went back to the V10 and removed all midi mappings and it worked. Started chopping down the factory mapping and found that these two lines both being present causes the issue:

DNC_FXSEND_DECK
deck mixer1 effect_fxsendreturndeck ? constant 0.0 : deck mixer2 effect_fxsendreturndeck ? constant 1.0 : deck mixer3 effect_fxsendreturndeck ? constant 2.0 : deck mixer4 effect_fxsendreturndeck ? constant 3.0 : deck 5 effect_fxsendreturndeck ? constant 4.0 : constant 5.0


DNC_FXSEND_ON
deck 1 effects_used 'deck' ? constant 1.0 : deck 2 effects_used 'deck'  ? constant 1.0 : deck 3 effects_used 'deck'  ? constant 1.0 : deck 4 effects_used 'deck'  ? constant 1.0 : constant 0.0


Corresponding lines from the xml:
	<map value="DNC_FXSEND_DECK" action="deck mixer1 effect_fxsendreturndeck ? constant 0.0 : deck mixer2 effect_fxsendreturndeck ? constant 1.0 : deck mixer3 effect_fxsendreturndeck ? constant 2.0 : deck mixer4 effect_fxsendreturndeck ? constant 3.0 : deck 5 effect_fxsendreturndeck ? constant 4.0 : constant 5.0" />
	<map value="DNC_FXSEND_ON" action="deck 1 effects_used &apos;deck&apos; ? constant 1.0 : deck 2 effects_used &apos;deck&apos;  ? constant 1.0 : deck 3 effects_used &apos;deck&apos;  ? constant 1.0 : deck 4 effects_used &apos;deck&apos;  ? constant 1.0 : constant 0.0" />
 
Slight correction- those above two mappings seem to cause the first stemfx to not work but all subsequent ones to work, but other ones to work. With the default mapping, no stemfx are working. Something is wrong with the factory mapping.
 
Can you try a hack trick ? :P

DNC_FXSEND_DECK
deck 1 effects_used 'deck' ? constant 0.0 : deck 2 effects_used 'deck' ? constant 1.0 : deck 3 effects_used 'deck' ? constant 2.0 : deck 4 effects_used 'deck' ? constant 3.0 : deck mixer1 effect_fxsendreturndeck ? constant 0.0 : deck mixer2 effect_fxsendreturndeck ? constant 1.0 : deck mixer3 effect_fxsendreturndeck ? constant 2.0 : deck mixer4 effect_fxsendreturndeck ? constant 3.0 : deck 5 effect_fxsendreturndeck ? constant 4.0 : constant 5.0

Under no way (even if it works) this is a permanent solution.
It's just a test to help us understand something.
 
Thank you for the reply. Do you mean try that with the default mapping? Substituting that in with the default mapping, decks 1-3 appear to have stemfx working but deck 4 does not.
