I’m running lemur on Ipad, with a 16 channel MCU, and just simply created two “search” buttons that pop up when none of the select buttons are lit, one for “bank to the left”, one for ‘bank to the right" just until one of the 16 "channel "selected’ buttons are on again, then the script stops ad the buttons disapear. So if I select a channel by mouse, way out of focus of the MCU, it usualy takes a fraction of a second before the MCU on the ipad is showing the selected channel in one of the two banks again. Works for me…
