PresetSwitcher gives you simple, direct control over your Bluetooth modeling guitar amp. It supports modeling amps that accept MIDI commands for preset switching. Since the app is free, simply give it a try with your amp... Switch your amp presets directly from your iPhone or iPad. With optional footswitch support, you can control your amp hands-free while playing using a compatible Bluetooth MIDI footswitch. FEATURES • Switch presets directly Quickly toggle between your configured amp presets using large, clear buttons. • Bluetooth MIDI footswitch Control your amp while playing without needing to reach for your iPhone or the amplifier itself. • MIDI Learn Map your footswitch buttons to your presets and customize controls to suit your playing style. • Flexible button assignment Configure the preset buttons to match your specific setup. • Portrait and landscape modes Use PresetSwitcher comfortably on both iPhone and iPad. Footswitch support is available as a one-time in-app purchase. PresetSwitcher was designed for use with compatible Bluetooth modeling amps and Bluetooth MIDI footswitches. I have personally tested it with the following amps: SPARK GO, SPARK MINI, and VALETON GP-5.
