Hi A&H.
This was the first point I made to the local A&H rep, and to your employee hosting a dLive presentation in Copenhagen. The “Width” Press-And-Hold feature of the EQ is simply the single biggest brain fart on the C Class surfaces, and this opinion has now been confirmed by every single C Class user I have talked to.
Since it is too late for you to implement the full EQ pots, you have to at least make the “Width” button latchable. With my finger on the screen I can easily control frequency and gain, but Q value is not editable via touch input. So of course the most sensible thing would then be to have the width knob below the screen, without having to press and hold the button 🙂 make it latchable, problem solved!
Anther fix could be to make the touch and turn dial default to the width parameter on the active EQ band.
Please please please take care of this in next firmware update.
