There isn’t a way to customize whether the Hotswitch/Performance switch functions in latching or momentary. Every algorithm was designed to be one or the other; where “Hotswitch” is used, it’s always latching. However, H9 has a function called “Expression Pedal Value” that will momentarily take your settings to the Max range settings of your expression ranges. This can be set to behave like a momentary Hotswitch. I explain in this video:
In addition, with an adequate controller, customizing latching/momentary functionality can be achieved via MIDI by programming press & release states per button.
Yes, I tried that too today but unfortunately it seems that when using the expression trick it also applies to all algorithms…I use the H9 with a third party three way switch, Hotknob is the middle one. So you can set the middle switch only either to momentary or latch generally.Would be cool, if it was possible to do this per algorithm. But that’s ok since I want to get another H9 🙂
