Closest I’ve seen is Yamaha’s “fader groups,” which aren’t quite the same as DCAs. I don’t see how it could be implemented on the Qu though. Physical fader tracks go from -inf to +10. DCA control on the Qu allows a channel’s fader’s signal to go from -inf to +50. What should happen when a fader’s “true” level (original fader’s level + DCA master(s’) dictated adjustments) is > +10?

Extreme example to illustrate a point: Imagine you have a channel with it’s fader set at unity, and it’s controlled by all 4x DCA masters, and each DCA master is set at +10. That gives you +40 on that channel. That channel’s own fader track only goes up to +10: you can’t accurately represent that channel’s signal level on its fader. If you then pulled the channel fader down to +5dB, then you’d still be at +35, which is still > that +10 that the fader track allows for. Should the fader then snap back up to +10 to show the signal level is > +10? Perhaps the channel fader motor should lock at +10 until DCA adjustments are made? That would be all sorts of awkward, especially as the Qu16 doesn’t have dedicated DCA faders and scene recalls can re-organise the custom layer (potentially removing the DCA master faders.) It’s the same problem even if the channel is only controlled by 1x DCA master. What if the channel’s own fader level is +5 and the DCA master is at +6? You’re at +11 and the fader track only goes up to +10.
