Me too. Would appreciate that!
I just received my Gigcaster and I enjoy the minimal setup with StageTraxx and the Gigcaster. While StageTraxx manages lyrics, chords and the backing tracks, it also controls everything on the Gigcaster - e.g. the switching of guitar patches or turning on harmony for the voice channel for verse / chorus / solo. So as the second component of my rig, the Gigcaster is my guitar effects board, my vocal effects board and of course my mixer.
Right now I have to use MidiFlow on my iPad to replace CC-Messages that is sent from StageTracks with the SysEx Messages the Gigcaster reqires. It is quite tiring to assign those things manually in MidiFlow. And I fear that this setup (Multitasking on iPad !!!) is prone to errors and malfunction.
SysEx-Messages directly supported in StageTraxx would be great!
