The Electric Music Box - Series 200e

   0 reviews  -  1362 views

    This year we're celebrating 45 years of building bizarre electronic musical instruments. What better way to celebrate than to revisit some old instruments - namely the 200 series Electric Music Boxes, manufactured from 1970 to the mid '80's.

    Why the 200 series?

    Because it's Don's favorite synth, and he wants an updated version.

    Updated how, you ask. Still straight analog synthesis. Still programmed with knobs, switches and patchcords. Same power supply voltages, same form factors. In fact, completely interchangeable with 200 series modules built in the '70s.

    But with some new twists.

    For a few years we've been designing MIDI controllers (Thunder, Lightning, the Marimba Lumina, and the Piano Bar, among others). But our controllers couldn't even talk to our own 200 series instruments (designed before MIDI was even dreamed of).

    Situation rectified. Check out the new 225e. The top half is a full-blown MIDI interface that can relate every nuance of expression that your controller can produce to any aspect of the 200e's sound palette.

    The 225e's bottom section addresses another shortcoming: how do we save a patch so that retrieval is instantaneous at some future time? Simple! Just push the store button, name the preset, and your preset is forever stashed.

    Other improvements include internal MIDI buses, invisible supplies, high density modules, more voltage controlled parameters, the addition of a router for signals and control voltages, the merging of a swirler with the system interface, the addition of velocity to the dynamics manager, and a reworking of the output section of the complex oscillator.

    Functionally new modules include an arbitrary function generator, a duophonic pitch class generator, a triple morphing filter, a multi-dimensional kinesthetic input port, and a pitch shifter / balanced modulator.

    Select some modules, button them up in a 200e cabinet, and you're off and running with the most sophisticated analog system ever built.


    The Model 201e - 18 WLS Powered Cabinet is the vessel that houses and provides power for 200e series modules. Made of select Eastern Walnut and black aluminum "boats", the 201e will withstand the rigors of travel with ease.

    The cabinet folds for traveling, and is shown in its extended and folded positions. Folded, its dimensions are 27 x 12 1/2 x 8 inches.

    Power supplies and distribution rails are concealed in the depths of the 201e. An external desktop supply provides 12 volts D.C. to the 201e. Alternatively, the system may be powered from a 12 volt battery. LED lamps are provided for dimly lit stages.

    The cabinet is available with a sturdy protective shipping case, which measures 30 x 17 x 11 1/2 inches and features cushy foam inserts.


    Similar to the 201e - 18 WLS, except it accommodates 12 panel units and is 18 1/2 inches wide. Its carrying case is 22 x 17 x 11 inches and features cushy foam inserts.
