How do I configure the EXP/ MIDI jack on Lex?

To configure the EXP/MIDI jack on Lex:

  • Press and hold the SLOW/FAST footswitch while powering up Lex.
  • Once both LEDs flash, release the footswitch.
  • Turn the VOLUME knob to select the function of the rear panel’s EXP/MIDI jack. The ON LED will change color to indicate the current status as you turn the knob.
    • Expression Pedal mode: GREEN (default) – Allows continuous
      control over any of the knobs in any direction with a standard TRS
      expression pedal.
    • External Speed Switch mode: PURPLE – Allows you to toggle between fast and slow rotor speeds with a Strymon MiniSwitch.
    • Favorite mode: AMBER – Allows you to recall a Favorite setting
      using a Strymon MiniSwitch.
    • Tap mode: RED – Allows you to control Lex’s SPEED option using a Strymon MiniSwitch.
    • MIDI mode: BLUE – Allows for the selection of three presets using a Strymon MultiSwitch Plus. Full MIDI functionality is available by sending MIDI Program Change messages via 1/4″ MIDI connection using a Strymon Conduit or MIDI EXP cable. Up to 300 presets are available via MIDI.
  • Press either footswitch to store the EXP/MIDI jack mode and begin using Lex.
