I was looking for some sort of settings in the software as opposed to scrolling trough the menu pages on the H90.
On H90 Control, if you click on System up top and then click on “External Control,” you can see all the parameters that are mappable. Click on anyone and you will see the option to assign a control source, which could be any of your switches or expression pedals.
The only other issue is that the H90 – with my quick tweaks to the settings to try to quickly resolve this – can not discern between an on/off and a momentary switch… but, I will check the settings on the H90 a bit more in depth when I have time to fix this.
Which functions are you trying to assign? In this same list I just mentioned, notice some parameters have an “M” in parentheses. (M) These are the momentary parameters.
