I am a relatively long-term user of Band Helper but have only recently tried to use it with Bias FX Mobile on iPad. I use Band Helper live to call up song titles, lyrics, and performance notes, as well as to automatically switch to Bias FX presets on a per/song basis. So far, so good. I'd like not to have to create two (or more) presets/song to move from, say, rhythm guitar to a lead solo; much better would be to switch to a higher gain setting or amp by way of a control change within the same preset. Try as I might, though, I'm failing to be able to do this. I've read many posts in this forum about people who have done this with various apps--even iPad apps--but I've yet to find one that has worked for me. Any help would be greatly appreciated!
