Red Panda pedals with USB receptacles also support 1/4" TRS MIDI input via the CTRL port, with MIDI in on the tip.  Use our web editor to configure the CTRL port for MIDI In (TRS).  Then scroll down and click Save to update your pedal.  The setting will be remembered when power is turned off.  You can set the MIDI receive channel on the editor's Config page.

Connect the MIDI output to the pedal's CTRL port using a TRS or TS patch cable.  Some Disaster Area Designs MIDI controllers require a TS cable, while most controllers use a TRS cable.

This is a non-standard MIDI interface, because there is no optocoupler on the input, but it is used by many guitar pedals.  You will need a converter or a MIDI controller with 1/4" TRS outputs, which are available from Empress Effects, Disaster Area Designs, Morningstar, and others.  Those devices contain an optocoupler to prevent ground loops.  Simple 5-pin DIN to TRS MIDI cables are also available and will work in many cases, but they are susceptible to noise caused by ground loops. 

The TRS connector wiring is:

  • tip: MIDI input
  • ring: not used
  • sleeve: ground

The wiring matches the MIDI Manufacturers Association Specification for use of TRS Connectors with MIDI devices.  It is sometimes referred to as "Type A" (Korg style).  Since our CTRL port does not have an optocoupler, to fully comply with the MIDI 2.0 standard you should use an adapter or a cable with an inline optocoupler (such as the Strymon MIDI EXP).

If the TRS MIDI output jack polarity is configurable, set the output to tip active (tip = MIDI in on the pedal).

TRS MIDI converters verified to work with Red Panda pedals:

  • Disaster Area Designs MIDI controllers and TRS MIDI converters
  • Empress Midibox2
  • Morningstar Engineering controllers with TRS MIDI out (1/4" or 3.5mm)
    • Use "MIDI Out - Tip Active" and a TRS (stereo) cable
    • MC8 Setup (applies to all Morningstar controllers)
  • Morningstar MIDI Box
    • Ports 1 to 6: use tip active, ring unpowered/floating
    • Ports 7 and 8: use a 3.5mm TRS to 1/4" TRS cable wired tip-to-tip and sleeve-to-sleeve, with ring disconnected on both sides (thanks to Justin Kosler).
  • Strymon MIDI EXP cable (standard orientation)
  • Strymon Conduit
  • Meris MIDI I/O (limited - see below)

The Meris MIDI I/O daisy-chains connected pedals and passes MIDI from the output of one pedal to the input of the next.  Our pedals do not transmit MIDI via TRS (only USB), so they will not retransmit MIDI to following pedals.  You can use one of our pedals in the last jack (e.g., #4), but no MIDI will be sent to the MIDI output.

Note: your Particle or Tensor may require a firmware update to enable TRS MIDI input.
