On the SQ-Pad app you can use the horzontal slider below the EQ graph to change the Q-factor of the EQ bands. for the LF and HF band it is possible, when you move the slider fully left, to change the filter type from Bell to Shelf. The console follows that changes. But on the console it is not possible to do that. Also on SQ-Pad only the slider can do that, not via the numeric parameter fields when you extend the EQ view.
I would like to have also on the console the possibilty to switch from Bell to shelf and vice versa.
BTW: Today I found out that for the QU-Series there is a spectrograph.
