Good morning and Happy New Year! I was starting the year off right with a early morning jam and connected my iPad to my full keyboard controller.
Toggle/Momentary buttons can only be controlled by a MIDI note for now, so I assigned a key. Even though the toggle is set to not momentary ( with the X inside the square parents) the toggle is only active when the keyboard key is pressed. It only acts as momentary.
Bug? Setup error?
Thanks for reporting this! It is a known bug that will hopefully be fixed in the next update 
For now, you can stick a flip flop after the button to get the latching effect.
Thanks for the workaround! That worked great. I don’t think I loved a software as much. Much love and props for the things you do.
Is there a known bug thread on the forum?
There is not, but if you look through support you can see the other issues people have had - most of it is due to aggregate devices not being supported because of a bug on Apple’s end.
