This one in via André. You can find full details and more images on Elektronik-Projekte in German. The following is a translation of part of the description in Googlish:

"This synthesizer is my largest project so far. I have built good 3 years out (1989-1992) and in fact the device has never been properly finished. The basic functions are, however, almost completely, ie You can elicit this synth sounds absolutely fantastic.
The programming of sounds is a bit cumbersome: About the control keyboard 48 parameters can be set by the oscillator, filter, affecting the amplifier and the envelopes. Here are some pots were really served well, but that would have been too costly.

Here are a few technical details are the synthesizer:
* Keypad: 4 octaves (not velocity sensitive)
* Tone Generation: 6x DCO, 6x DCA, DCF 1x, 1x Noise
* Polyphony: 6-coherent or 3-consistent when using 2 DCO per voice
* 4 FX buttons: pitch up, pitch down, modulation, chord memory
* Operation over 12 buttons and 4-digit LED display
* Direct Sound for an additional keyboard with 32 keys
* Interfaces: MIDI In, MIDI Out, MIDI Through, Tape, Audio Out, Headphone "
