Signals on the Bus Cable

All modules are connected with a 10-pin ribbon cable that runs below the modules. Each module is plugged onto this bus cable with a 10-pin connector.

A master module is usually the source for this ribbon, supplying both power and control signals (derived from midi).

The master module has 2 connectors for 2 separate ribbons.

The top 4 pins are used for power. The remaining 6 pins are all derived from MIDI by the master module.

NOTE: the control signals should be considered as output only, since they are pushed by the master module.

NOTE: All modules use the same 5V / Ground rail so modules need to take care not to induce a ripple voltage which can introduce noise.

How to make your own ribbon cable

You can of course make your own, it's really nothing special. Here is a general guide on how to make those:
