Making an option where the master fader switches to a fader that follows whatever channel that is selected either from the MCU itself or from within cubase by mouse or keyboard. Just like the fader on the cc121. Or even better making an option where any on the 8 channel faders can be set to do this.
Making an option where one or more channel faders can temporarily be locked to control a certain channel while the other faders can switch around as usual.
An option where the jog wheel can mimic the mouse scroll wheel for dialing in parameters like a steinberg controller AI knob.
