I noticed some inconsistency in the user interface regarding FX to FX sends.
E.g. FX > FX Unit 1 > SENDS TO Fx Unit 1: In the FX block, the control for sending FX 1 to FX 1 is greyed out. Or better said: The UI designer put a square grey box on top of it. Kind of logical to me, since you wouldn’t want to generate a feedback loop through your FX chain.
However, when using Mix Select and select the FX1 mix, the fader for FX1 DOES show up, but of course, has no effect. It’s just a useless UI element there and has no function at all. Maybe best to keep things consistent and also put a grey box on top of that fader too?
