Has anyone figures out an easy way to control multiple synths from one PE without connecting and disconnecting from each synth?

I currently have an MKS-80, Cheetah MS6, and a JX-8p.
I only have one PE.

I need each synth to have access to my sequencer, and to the PE at the same time, so I don't have to continuously patch/re-patch.

Thanks!
