I’m not sure if I understood your question fully, so please let me know if I have misinterpreted it.

The OT can send MIDI Program Change messages to the Analog Four to cause it to change its pattern. To do this, you have to activate the send function on the OT and the receive function on the AF, as well as set the MIDI channel number on which the PC messages are sent.

What do you mean by patch? As far as I know, there is no documented MIDI message to send to the AF to change its Kit or Sounds. Some developers have deciphered the MIDI SysEx implementation of the AF and would be able to create an intermediate program to change the Kit or Sounds in response to a MIDI message from the OT.
