Got it figured. I did a deep read of the code on GitHub (thanks so much for the open source
https://github.com/amowry/warbl/tree/ma ... bconfig/js) and found within the web app some of the cc codes that are sent to configure the WARBL.
CC 102, 60 selects tab/instrument 1
CC 102, 61 selects tab/instrument 2
CC 102, 62 selects tab/instrument 3
All sent from Loopy Pro on channel 7 worked great. I get the flash of the led on the WARBL and the tab moves within the WARBL app on iOS.
Cheers!
