"Near mint, no issues. This instrument has been used with the greatest care. Very few light marks, hardly any signs of use. Original signature by Tom Oberheim on the front. Later "Marion Systems" units with the "M" logo on the panel come with a printed signature and different knob / controller caps.

Comes with:

original switchable PSU 110-240V (EU plug cable)
documentation card for MIDI-CV interface & patch panel, manual, recall sheets (all are photo copies). original box"

"This Thingamakit is effectively a kit version of the Thingamagoop. There are two "eyes" (green and blue) that you can use to control the main and mod oscillator to make all sorts of cool sounds.

This is unassembled with all of the parts, manual, and drill template in the original box."

Siluria, firmware v1.1 - using WAV files from SD card, demo #2


video upload by Gechologic

"Another demo of the new funcitonality where Siluria uses WAV files from the SD card (instead of line input or radio), this time with a longer and more interesting samples. All effects can be applied, plus there is one more function: the playback speed can be controlled (in both directions). The wavetable sound engine has been expanded as well, and new effects were added, which will be demoed later.
The sound here was recorded directly in the unit - it is possible to play back a WAV file and record the resulting mix (exactly as you hear it in the headphones) back to the SD card for later use."

"Hi folks!
'Collapsing Society' — a world in decline, yet hope remains. May we rise above ignorance and power games, to remember what truly matters — respect for life, in all its forms. Please put your headphones on and enjoy the beats of the two analoge machines… Peace&Love to all folks!🖖👽"
