The Select Bus breakout provides access to the MIDI-based Select Bus protocol as used by some Expert Sleepers modules - the disting mk4, disting EX and General CV - as well as a handful of modules from various manufacturers, including the Malekko Varigate 8+, Macro Machines Storage Strip, and the Make Noise Tempi and René mk2.
Using the breakout you can cause multiple modules to simultaneously save or recall presets, remotely controlled via MIDI.
The breakout can be used either to drive the Select Bus, or to output the bus messages as MIDI. The Select Bus is not a 'multi-master' specification, so if another module is driving the bus, the breakout can only work in the latter mode.
If the breakout is driving the bus, its output is effectively a MIDI Thru.
Pricing & Availablity
The Select Bus breakout is available now, in kit form only.
The kit is available from Thonk.

disting EX compatibility
This module was created quite early in the history of the Select Bus, and the most common electrical implementations have changed somewhat since then. As sold, it's compatible with the disting mk4 and older modules by other manufacturers. With the disting EX, it can be used to receive from the Select Bus, but not to drive the Select Bus.
For full compatiblity with the disting EX, make the following component changes:
Resistor R4 - was 470R, now 33K
Resistor R7 - was 10K, now 680R
Diode D1 - remove
