MIDI controled CTRL ALL?

Hey gang!
Is there a way to change parameter value for all tracks, like CTRL ALL function only via CC? Like a separate channel or something?

Not exactly.

You could set all the M:S’s tracks to respond to the same MIDI channel number and then control one parameter on all tracks using a single MIDI CC message.

Bummer.
It might be a useful workaround, but I need the tracks on separate channels to be able to mute them.

Then you will need an intermediate MIDI processing device between your controller and the M:S to achieve what you want.

Right. Thanks @PeterHanes
