Analogue-sequencer

Hi All
 
I've been having a fun time with midi cables. ;)
 
I'm trying to midi-merge the outputs from a Sequentix P3 and a GenoQs Nemo
so I can control any synth from either sequencer without swapping cables.
 
The Nemo is slaved to the P3.
 
The issue I seem to hit is that any synth I have set up with clock-sync'd
delay goes a bit haywire (ie the delay shuffles rather than bounces). I
suspect the merged clocks are the issue.
 
I'm using a Roland/Edirol UM550 to do the merge.
 
Have people successfully found a way to do this, or do you tend to hang
different synth modules off different sequencers and manually repatch when
you fancy a change?
 
Or perhaps it's the UM550 not handling clock merge very well?
 
Any advice appreciated. :)
