I think, the solution might be a standardized digital bus for sequencer
orientated modules. Accessible from the front side of the modules. 10 pins
should be enough for a 5Bit-addressing (=32 Steps), clock, start/stop,
reset and ground and +5V. Doepfer could use the same ribbon cable that is
used for the supply voltages.

If such a bus exists, modules and keyboards simply could be combined.
