When Universal Audio Pedals were first released, musicians eagerly wanted MIDI control for them. Unfortunately, none of the UAFX pedals initially had MIDI capabilities. This limitation made it difficult for musicians to effectively control and integrate the pedals into their live performance setups.


What made this situation particularly frustrating was the incredible sound quality of these pedals. They easily ranked among the best-sounding options available, yet offered limited control. Thankfully, with the release of UAFX 2.0, users now have full MIDI control.



Why the Need for MIDI?

MIDI control allows users to recall presets and adjust effect parameters on UAFX pedals using a MIDI foot controller. This feature is essential for musicians who cannot tweak effects while simultaneously stomping on multiple pedals during a performance.


With MIDI, musicians can also connect an expression pedal to a MIDI controller. This setup provides smooth, continuous control over UAFX effect parameters.

USB MIDI Connection

To utilize MIDI, ensure your UAFX pedal is updated to the latest firmware. Additionally, make sure your UAFX Control app is also up to date.


UAFX pedals receive MIDI via their USB device ports. Therefore, you will need a USB host port to communicate with them. Morningstar PRO controllers feature USB host ports that allow you to connect directly to and control UAFX pedals via MIDI.


If you want to control multiple UAFX pedals, you can connect a USB hub to the MC8 PRO's host port for additional connections.

If your MIDI controller lacks a USB host port, you can purchase a MIDI USB host to connect to your controller. This will enable you to control UAFX pedals as well.

Two Categories of Pedals

All dual-footswitch Universal Audio pedals (14 in total) have been updated with MIDI capabilities. This includes popular models like the Lion '68, Dream '65, Del-Verb, Ruby, and Starlight.


However, not all pedals have preset capabilities or accept Program Change (PC) messages. Only pedals equipped with preset footswitches can store presets and recall them using PC messages.

Pedals without preset capabilities only accept Control Change (CC) messages to control effect parameters.


What Can Be MIDI Controlled?

Universal Audio has delivered comprehensive MIDI implementation for all updated pedals. In addition to recalling presets on pedals with preset capabilities, users can control nearly every effect parameter available on the UAFX pedals. This includes MIDI Clock for time-based effects. Controllable parameters, along with their corresponding CC numbers, can be found in the UAFX Connect app and in the pedal user manuals.
