UAFX pedals Now with USB MIDI Control

Learn how the free UAFX 2.0 update expands your tones.

With the latest UAFX 2.0 update, your pedals just got a whole lot better. Now you can use MIDI over USB to recall presets and shape tones in realtime — all through the USB-C port on your pedal. Whether you’re building a modern pedalboard or running a show full of lights and tracks, UAFX pedals now fit perfectly into your MIDI-powered world.

UAFX 2.0: MIDI over USB

How It Works

With UAFX 2.0, every dual-footswitch UAFX pedal can now receive MIDI directly through its USB-C port. 

Each pedal acts as a USB device, connecting to a USB MIDI host such as a Morningstar MC8 Pro, Disaster Area Designs DMC.micro Gen4, Mortrix Midi Switcher, or computer. It is possible to use a USB hub to connect multiple UAFX pedals for simultaneous MIDI control. In many cases, four or more pedals can be controlled at once, depending on the USB MIDI host interface capabilities. 

With USB MIDI host to 5-pin DIN converters like the CME H2MIDI Pro, it is possible to control up to eight UAFX pedals from 5-pin DIN MIDI controllers, such as the Jet Pedals Unity6, The GigRig G3S, RJM Mastermind PBC/6X, or even the Neural DSP Quad Cortex.

From amp emulators like Dream ’65 and Lion ’68 to effects like Starlight Echo Station, Astra Modulation Machine, and Galaxy ’74 Tape Echo & Reverb, UAFX pedals now speak full MIDI.

You can recall 128 presets (Program Change 0–127), automate any parameter using MIDI CC,* and sync time-based effects to your session tempo via MIDI beat clock.

What You Can Control

• MIDI opens up a world of possibilities inside your UAFX pedals:
• Recall any saved preset instantly. Load your favorite amp, delay, or modulation sound directly from a MIDI controller with 128 preset slots (Program Change 0–127)
• Change multiple pedals at once. One button press can switch your Dream ’65 to a lead preset, your Starlight to a dotted-eighth delay, and your Golden Reverberator to a shimmering plate reverb
• Turn effects on and off. Toggle vibrato on the Ruby ’63 or modulation on Astra mid-song
• Control parameters. Adjust Enigmatic’s overdrive gain or Galaxy’s delay feedback in realtime with an expression pedal via MIDI CC (Control Change)*
• Step through modes. Switch Astra between chorus, flanger, or tremolo, or move between Woodrow’s preamp boosts
• Switch Amp Channels or Cabs. Use MIDI to select speaker cabinets or channel switching on amp pedals like ANTI 1992 and Knuckles ’92 Rev F
• In short, if there’s a knob or switch on your UAFX pedal, there’s a MIDI CC for it. 

Please update your pedal firmware via UA Connect to receive new footswitch modes (amp pedals), updated Bluetooth, wired control and USB MIDI control functionality.
