My issue is the Rechannelizer and the mapping of the different channels to separate parameters within the Rechannelizer.
To use the knob to switch Input ch 1 from output ch 2 to output ch 3 within the Rechannelizer it is nessary to switch the different parameter within the Rechannelizier on and off … eg switch parameter 1 (1-2) off and parameter 2 (1-3) on.
Moving the knob from 2 to 3 should have the same effect like switching form radio button 1-2 to 1-3.
it is possible to do this with radio buttons … but it requires many buttons: 2 input channels and 8 output channels are already 2 times 8 Radio buttons… 2 knobs would be more comfortable and easer to handle
