[Effect pedal, MIDI on a Jack.[SOLVED]]

Hey Bruno,

I'm a bit new to the pedal, but I did indeed try this 2-3 times. It appeared to store the setting correctly.

Just to be crystal clear:

• set Expression mode: MIDI

• set MIDI Thru: (L) MIDI Out

• Global Tempo: R (L) global tempo

• MIDI Channel: 1

Then "power cycled" which I assume means to disconnect and connect the power adapter.

Should the knobs send MIDI that correspond to internal controllers, and also receive these controllers?

I noticed zero MIDI input on my interface (iConnectivity MIO10) and also, even configured to send clock, Logic did not set the tempo of the pedal.

I just tested it again and the polymoon's tempo remains constant no matter what tempo I'm sending. (sad face™)

 

Just to clarify, your wiring does not have any resistors inline? I'm doing a strain pin->pin wiring based on your grid-sketch above.

Also, thank you again for taking the time to explain this to us.

Ok,

Try to simply do this, the point is to connect the 5V of the MIDI out to the 5V of the MIDI In to get the input optocoupler acting.

Works fine for me on a Polymoon, receive and send. And cabling example:

Normally the 220ohm already present in your MIDI output acts as current limiter, no need for more resistor.

Hey Bruno! Thank you for posting these details. I just bought a polymoon and was keen to build a single TRS > MIDI In/Out. I followed your wiring precisely, even verified it with a continuity tester and it doesn't appear to work. The only mistake I feel I could have made is having the view backwards. The pin 5 is marked on the back of my connector, so I assumed this was pin 5 in your drawing. Is it possible that this is inverted and shows the pins from the connector end?

 

Suggestions are welcome! I'm excited to make this work.
