The simplest "bus board" is nothing but a 16 pin ribbon cable with several
female connectors (10 or 16 pin, according to the connectors of the modules)
which are attached to the bus connectors of each module (instead of the bus
cable delivered with the module). We do this now and then for special
applications (e.g. if there is not sufficient space for a bus board). But
it's recommendable for a few modules only and for simple applications
because of the voltage loss. The cross-section of the ribbon cable is much
less than the pcb tracks of the bus board (and has consequently a higher
internal resistance). This causes a much higher voltage loss than the bus
board. I'd not recommend it if VCOs are among the modules. But for control
voltage modules only (e.g. LFO, ADSR, Random CV, joy stick and so on) it
should work.
