I’m reopening the subject because I’ve finally found the system that suits me best for managing certain effects modulations at once with a pedalboard plus one hand.
For my birthday, my children gave me a 3" smartphone and a 3" TP-Link wifi router to use with my 29.5" guitar.
Small equipment easy to use and light to carry.
This will allow me to tap less on my pedalboard and use more fingers on this phone fixed to my guitar.
It is my new supplementary touch controller driving my plugin host Gig Performer in Open Sound Control mode.
I chose Frederik Bertling’s OSCAR OSC controller for its simplicity and ease of use.
Incidentally it also comes with layouts to drive Reaper and RME Totalmix.
All this works perfectly, and all I have to do now is practice playing while manipulating the pads and faders. It’s already starting to give promising results.
I used this tutorial to implement this configuration:
