Makes senseI use the H9 Bluetooth app on my phone or computer to change patches. It'll do two H9s at one time.
However, I don't have to change patches on the fly, as I would if I gigged.
The app does it fast enough for studio work, but the pedals can be programmed with patches in the order of a set list, or just with favorite presets, and it'll cycle through them quickly. I haven't bothered with that, I just pick stuff with the app.
