I have not had this issue however, I’m probably not putting mine to as challenging a service as you are placing yours. Some users have reported that their adaptor cables don’t seem to fit snugly in the pedal MIDI port.
From what you describe, it seems like you have a loose connection from the pedal MIDI port to the cable. You could probably ask support@singularsound.com to consider replacing your pedal if it was under warranty when you bought your first MIDI Sync Adaptor. Wouldn’t hurt to ask.
Some options to consider:
Fasten your pedals to a pedal board and leave the connections in place. This should place less wear and tear on your pedal, port and cable.
- Try to wedge something between the barrel of the cable and the port to hold it more firmly in place.
- You could try to gently crimp the cable barrel with channel locks or a vise but that’s kind of risky.
- Modify your pedal to use TRS-to-MIDI; the instructions and schematics are on the forum. I think nepali_brother was one of those users.
Anyway, please let us know what you come up with as a solution.
