Prototype of the MOTM-440 module, hand-built by Juergen Haible (read more here). If you follow the cables, the trigger outputs of the TR-606 are patched into the MOTM-320 LFO sync input and a MOTM-800 ADSR EG trigger input. An Electro-Harmonix Deluxe Electric Mistress (reissue) is leaning against the desk support on the right.
