found the reply in another topic, so i’m sharing it here:
I’m going to attempt to change patterns via midi from my MDUW to A4. I just want the pattern change information from my MDUW to link to the A4 - so pattern A1 to A2 on the MDUW will make the A4 follow suit. According to the text that came with the 1.06 upgrade this should be possible.
“Program change can now be sent or received changing or enqueueing the corresponding pattern. Enabling is done is the GLOBAL - MIDI CONFIG - MIDI SYNC menu. Configuration of the MIDI channels is done in the GLOBAL - MIDI CONFIG - MIDI CHANNEL menu”.

It worked. Changing patterns on the MDUW will change patterns on the A4 - 1:1 match. This works very well for my workflow as I generally like short 16 step drum patterns with lots of fill patterns and 64 step synth patterns.
I set both machines to receive and send program change information, and set both machines to utilze channel 10 for this function. They linked up beautifully.
Aside… since my machinedrum patterns are only 16 steps and my A4 patterns 64 steps, I was concerned that it would change the A4 pattern prior to it’s completion. This is not the case, it’ll wait until after the 64 step to change… no timing issues here
