Idea:
I would like to control my amp’s 7 pin din selector with a pedal that sends midi commands.
There is a very small selection of gear out there that does this and i feel like it would be great to have something i can add to my amp’s chassis instead of having another box to keep track of.

map pin config:
Pin 1. +17VDC supply to pedal
Pin 2. not used
Pin 3. Ground this pin to detect footswitch
Pin 4. Ground/Common
Pin 5. Clean/Bypass
Pin 6. Ultra/Crunch
Pin 7. Effects



How could i go about creating this solution?

 

So you have a pedal connected to your amp via a 7-pin DIN cable.
What is it that you want to do with this?

 

The amp uses a 7 pin din cable to select different amp channels/functions according to the map below:

map pin config:
Pin 1. +17VDC supply to pedal
Pin 2. not used
Pin 3. Ground this pin to detect footswitch
Pin 4. Ground/Common
Pin 5. Clean/Bypass
Pin 6. Ultra/Crunch
Pin 7. Effects

I would to know what type if circuit i would need to design to received a midi command sent from the midi out of my ax fx unit and turn on and off the relays related to the 7 PIN DIN map.

 

There is no need to post the same data twice.

So what I read is:
AX FX ->MIDI->black box->7-pin DIN->amp

The black box controls three pins plus common:

Pin 4. Ground/Common
Pin 5. Clean/Bypass
Pin 6. Ultra/Crunch
Pin 7. Effects

You can use an Ardino to read the MIDI the commands. That is the hard part. The rest is easy.

i had a feeling it was going to go the way of an Arduino. Lol

I doesn't have to be. Arduino just happens to be the most popular kid on the block. I don't do Arduino.
