It would be great if the was an adjustable “FINE” control button for smoother more granular fader movements during a performance like there is in the Mixing Station app.
There is, just move your finger away from the fader knob to the right or left, the further you move it the finer the control. It is the same with all A&H apps.
Why is it unprofessional? On the Siundcraft Ui range you hold your finger on the fader and eventually it switches to fine control. In the heat of the moment I find the AH method more reliable.
I am just saying that there is a more consistent method used in Mixing Station. Right now, I open the Mixing Station app just for the FINE control button.
