Hi David, I'm mapping an XTouch compact to MS-XM32 on a Samsung Tab A with considerable success.
I'm noticing that the screen freezes from time to time, only while connected to the controller. The touch surface continues to function but the screen does not update until a MIDI message (any) comes from the controller. This is persistently happening in the channel EQ page, when adjusting the EQ from the screen, about 2 seconds after initial touch. This is also fairly common in the MIDI assignments and Layout/Layers file management pages but not persistent in the same way. I have not noticed this glitch on any other pages besides those.
I've ordered a cable to connect my iPad to see if the issue happens there.
Thanks for the continued support
