I keep mine, because it's a REAL benefit to save presets. If you want to step into the modular world, i recommend the Neutron from Behringer. Stunningly more possibilities than a Grandmother or Mother-32. I know, it's Behringer. But the Neutron just blew me away. I'm not on a budget, i own the DFAM, Sub Phatty and Sub37 on the Moog side of things, but the Grandmother is just not competing with Behringer's attack on the modular/analogue market.

I believe the matriarch can send different things from its clock out. Check the global settings on that front.

I’d like to find out also, have you found anything on it yet?

Forget the devices specifically (as it doesn't matter). Think of the core concepts. Clock is coming from the grandmother to the Mother, then the clock is being sent half speed from the Mother 32 to the DFAM. Easiest way would be to take clock out from GM into a Mult, then one into Subharmonicon tempo in, and another the tempo in on the M32 like in this video.

DFAM doesn't have MIDI capabilities so you'd need a CV to MIDI converter, or just stick with CV as in this video :)

no MIDI at all?

C.T. Blaze nope

The menu diving isn't necessary, but they always show it in the Moog videos in case you set it to something else during a previous session and forgot. The Mother 32 specifically as that assign out isn't at ½ tempo by default. Sure MIDI on the DFAM would have been nice, but I my thinking has always been that the mother line is friends of eurorack, which is all CV 1st anyways. MIDI in on the Mother makes it friendly for playing it as its more a musical thing vs the DFAM which is percussive patterns; not something you'd normally think of for MIDI in euro rack anyways. (I do get from say a DAW You might want to send drum midi to the DFAM, but in that case you may have other external more traditional drum machines. Because DFAM isnt' really a drum machine. it's a percussive synth.) My $0.02
