Modularized Oberheim Double SEM System

A short demo of a custom double-SEM + two associated patchbays in one wooden cabinet. These SEMs has been slightly modified (some of its control ranges has been enhanced) and the patchbays (one per SEM) exteriorize all the inputs/outputs/controls of the SEM structure. In addition, some extra features has been added in the patchbays area, such as an inverter, a modulation VCA, a 2x4 multiple, and several amount pots of external control signals.
The patchbays' panels were hand-made manufactured, and they were painted and serigraphied in the same style as the SEMs colour and graphics.
All the work (except the custom wood cabinet) was made by Synthoma ( www.synthoma.net )
