How to sync the TOPOGRAF to a DIY clock source?

I made a simple DIY clock source from a 555N so that I could sync the various bits that need syncing, like the TRIQ164 and SEQ16 etc. (see attached pic.)
PIN 3 of the 555N is the output, variable with the potentiometer, which I patch into the CLK input of the modules I want to sync (the 4 cables at the top)
All works well for most modules, but I can't sync the TOPOGRAF with this setup as it seems to need a much higher frequency to "run".
I see on the MI Grids page that the clock input can be "External clock input, with selectable resolution (24, 8 or 4 ppqn) [pulses per quater note].
Is that true of the TOPOGRAF? I guess the resolution isn't selectable.
Does anyone know how it's clock works? What does the clock actually trigger?
Any any ideas on how to overcome this?
