I didn’t say you needed to be more clear, I just like to be helpful and I love talking about synth gear 
And, interestingly enough, I played with the pyramid a bit and there are a couple of clock contexts that make a difference. Maybe you or technobear will find this interesting. But, it looks like the only way to have a clock pass through is to somewhat cripple the pyramid.
An external clock is only gonna pass through when a midi port is set to THRU, otherwise while you can sync to the clock, it appears as though the pyramid has it’s own clock generator that’s simply configured based on whatever is read on the input. If one or both ports is set to THRU then the clock will simply be relayed to the output. If the midi output is set to OUT or OUT+THRU the external clock won’t get past the pyramid - you have to turn on SYNC for each port to get a clock to send in OUT or OUT+THRU modes and this clock seems subject to processing introduced latencies.
So, if you wanted an external clock to drive the synths you have connected to the pyramid, you’d effectively have to disable the pyramid’s ability to play any notes (you need to be in OUT or OUT+THRU for it to perform it’s sequences). Ah well.
I guess this means that I will be going with plan B, which is to use an external clock and some midi mergers.
