Method 1: In the H9 Control app:
- Pedal -> General Settings -> Use Expression Pedal, Aux Switch, or Both = Aux Switch, or Both.
- Pedal -> Aux Switch Mappings -> Set parameter 1
- Foot Switch 1 (Tip) [or whatever; just not one of the (… Momentary …) selections].
- Parameter Range -> Start = 0 End = 40.
Method 2: On the H9 itself:
- Hold Big Knob + right switch/Tap. Dial to Aux SW. Click Big Knob. Dial to KBO: —
- Click right switch/Tap. Dial to TIP [not TIP. with a trailing period. That’s “Momentary“].
- Click left switch/Active. Click left switch/Active once again.
- 0 will be the MINVAL. Click left switch/Active a third time.
- With the Big Knob, dial 100 down to 40, as a MAXVAL.
- Hold Big Knob+right switch/Tap to exit the system mode.
Either method will control the MIX parameter (or similar), at those range limits. Keep in mind that KB0 / Parameter 1 may be a completely different parameter, or scaled differently; depending on the algorithm.
