VERY RARE TO FIND ONE COMPLETE WITH KEYBOARD!

The modular synthesizer in the case has only minimal usage traces and was checked in 2017 by an audio specialist. A new power supply was replaced as a replacement for the original power supply. In addition, the slide potentiometer of the filter module was replaced by a slightly more gentle potentiometer.

In addition to the power supply new patch cables as well as the original patch cable (standard mini-jack), a 5-pin connection cable for the keyboard, the cover of the "Koffersynthies" and the original manual (or textbook) are included.

All modules of the Synthis work perfectly, the overall sound and especially the filter sound very high quality.

The modular synthesizer built in a suitcase has only minimal signs of use, no broken parts or other damages. It was tested in 2017 by an audio service and a new power adapter. So the slider potentiometer of the filter module is replaced by a new one.
