For some reason, either pressing the white or uv buttons (with or without Shift) doesn’t engage them, they only turn on when pressing them, and they turn off when you let go. Anybody else running into this?
They are set to be momentary switches. You can change this in the software to a ”latch” type push switch.
If you go to the settings page in SoundSwitch, can you right click these MIDI buttons to change the behaviour of this? I’m away from it all for a few days so trying to do this from memory.
