Drifting tempo / midi clock sync issues

So I’m getting some sync issues with my live setup.

Setup configuration A:
I have a monomachine sending master midi clock to an Erica Synths LXR which I use for it’s analog clock out which sends clock to an Erica Drum Sequencer module. 1st bar is fine and then it goes out of sync pretty quickly within 4 bars. Very very noticeable.

Setup configuration B:
I use a ER-M midi clock to send midi to the monomachine. The ER-M multiclock also sends midi to the LXR (which sends analog clock to the modular). I notice immediately that the TEMPO on the monomachine drifts pretty wildly. From 117, to 119 to 120.1, etc (with 120 bpm as the setting on the ER-M). This makes everything unusable.

Anyone getting similar issues? What am I doing wrong if anything?
