I saw a post where a guy had programmed the TouchOSC app for wireless bluetooth midi on an ipad communicating with a Yamaha MD BT01 plugged into a stomp. I went down this rabbit hole and I am blown away by how good it works and how pretty simple it was to create my own template and program it. I think it is a great way to control the stomp without bending over to use knobs and  having the tuner and tap tempo control at my fingers frees up the FS3 to control an additional stomp. i have templates
