Topic: Distortion after playing a while with stems
Hallo again (currently I am writing a lot here).
I have a MacBook Pro M2 with 32 GB (plenty I would say) together with a Pioneer XDJ-XZ (stable system actually).
Lately I've been experimenting with stems. I even have a dedicated MIDI controller to change the volume of single stems or of the whole melody or vocal section.
It's great. However, after playing around with this for a while, I have noticed that the output got more and more distorted. After I quit VDJ and start again, everything is back to normal.

Has anyone experienced the same or can anyone help me?

Cheers

Okay, I have a suspicion. Is it possible that the stems maximum volume can go above zero? Depending on the value of the fader it is no wonder that the sound will be distorted when one ore more values go above zero.
 
Depending on the script you used, it will act similar to eq, where center is 100% and above will boost the stem
 
Yes, that must be the reason.
I have simply mapped my Xone K2 faders and encoders to:
stem „Vocal“ and stem „Melody“.
But as the setting is made for the eq section where 100% is in the middle I guess the max is 200% and every time I push the faders to max it is much to loud. As you say.
I have to limit the max volume to 100%.
Could you tell me what I must write after
stem „Vocal“ or stem „Melody“ to limit it to 100%, please?
 
param_multiply 0.5 & stem vocal
This will divide the slider's value in half.
 
Thank you! I will try this! 👍
 
Unfortunately this has not worked.
I will explain what I've done:
I have mapped a slider to the following value:
Key 0-SLIDER16
deck 1 stem "Vocal"

Where do I have to put the line in order to make the volume 50%?

Thank you!
 
I have put it in the same line after my line. Which is not working.
 
param_multiply 0.5 & deck 1 stem vocal
 
This works! :)) Thank you!!
 
@DJDAD Now I need one info: I have the feeling that sometimes the volume settings for the stems is not reset when loading a new track. Am I wrong or is this the case? Then I need a setting to reset the volumes.I might be wrong though...
 
the setting > options: resetStemsOnLoad

will reset stems when a track is loaded (or not)

Or one can write an exact script and add it to the keyboard ONSONGLOAD mapping, to reset just what one wishes.
 
Thank you, IIDEEJAYII !
 
By default it was set to "Pads". So I guess in my case with the faders it was not active. No wonder I felt something strange. xD
