Just a proof of concept working 
SoftStep sending MIDI program change to Axoloti 1.0.7 Patch Bank
this to Controller object, create a Patch Bank, add patches to it and upload to SD card
that's it !!
oldies...iPad 1 - S1MIDI Trigger - Line6 Mobilizer
sending MIDI program change and notes
Been trying to do this but seem to be having trouble...
I have copied your loading patch @keyman and set it as the start up file on the SD card. I then loaded two patches onto the SD card in a patch bank. When I disconnect the Axoloti I can only load the first patch in the list with a program change. It won't then go to the second patch on the next program change. Can check I'm creating the patch bank and adding patches correctly?
So:
File > New patchbank
Add > A_01.axp & A_02.axp
Save
Upload bank table
Upload > A_01.axp & A_02.axp
Contents of the SD card looks like this:
Any steps I'm missing here?
Ok great to know you're finding the functionality useful.
Think you are missing first of all the Controller object, this will be the "foundation" all patches WILL have to have it "inside"!
As it would be tedious to do, in File > Preferences look below and point to the exact file name (no need for extension) example in objects create a dir - controllers - and save above patch (example prg.axs)
so add
controllers/prg to File > Preferences > Controller Object tick Enable !!
better RELOAD object (> File)
There were only a brief Controller object mention, think this is it.
Happy prg
