....> Concussor, MOTM, Oakley Soundsystems, Digisound and EFM modules.

EFM, well... not much information about them on their website
http://www.ele4music.com
Could anyone tell me what size the modules are Do they fit the Euro
rack or are compatible to any known synth (I mean power supply, internal
connectors etc. not the cv/gate standard...)

thanks in advance.
