"This is a Marion System SEM PRO, reissued by Tom Oberheim and purchased in 2016.
It is a one-owner item with no major scratches or damage.
Only the SEM PRO features Tom Oberheim's handwritten signature.
The original box is included, but the internal custom foam padding is missing.
The base of the adapter looked fragile, so it was reinforced with tape. Since it's a 24V adapter, the Marion System logo was laser-engraved to prevent mix-ups.
This adapter itself is made by Akizuki Tsusho. If you prefer a pristine unit, please purchase it directly from them."
"Original Moog Music branded pocket protector, featuring the classic Moog logo associated with analog synthesizers and electronic music.
Likely produced as a promotional or staff item, intended for use by technicians, engineers, or employees. A clean, minimalist design strongly tied to Moog’s legacy in electronic music and synthesizer history."

"Demo of some patches I programmed on the Korg Polysix. This unit has the KiwiSix CPU board installed that adds many features (like MIDI, sequencing, 512 presets etc) without changing the sound of the synth.
The polysix is a true 6 voice VCO VCF VCA analog synth and it sounds great. By design however the enveloppe is slow and the sound a bit dark due to an added post FX VCF (LM13600). A simple mod allows to bypass this and let the synth shines. With this mod you get a very snappy and funky synth whose SSM2044 filters gets very well along the built-in chorus/phaser/ensemble FX. This unit has this mod done.
From funky keys, to lush string pads, the P6 has a very large scope despite its very limited features.
Only bad point of the P6 is that it has a fairly high noise level. Some improvement can be made like in this unit by adding more ground wires, applying copper foil on the bottom case and adding ferite around wires."

Pics of the inside below.
"Serviced and fully working classic 6 voices analog poly synth.- brand new KiwiTechnics Kiwisix CPU board that adds lot of features (MIDI IN & OUT, CC, sequencer, 512 presets etc)
- all electrolytic capacitors were replaced (the P6 has many of infamous Panasonic CE capacitors that leak after decades of use)
- post FX VCF mod: this simple mod gives the P6 faster enveloppe and fuller sound. A must do on all P6, check demo.- improvement of the ground design by adding more and thicker ground wires, copper tape on the bottom case and ferrite around the data wires
- full calibration
Unit is fully working and sounds great. As expected with these Polysix there still is some light background digital noise due to design, but nothing major, check demo to hear how it sounds.
Cosmetic is good with some scuffs here and there, especially on the case as it often is the case on P6. One switch cap ("hold") is not original."
"New day, new instruments, different languages, different gestures, and it's to surprise of no one that I am not equally proficient in each one of them, especially when they are same-same but different (like with the OPXY vs Deluge).
I've listened to this recording for a good part of the day and I was getting nauseated, but I asked my girlfried to check it out, she genuinely liked it a lot, so that's why I am uploading it.
Day by day, I feel the need for a mixer (and maybe a more powerful computer), but the focus is practice, and give a spot to all the beautiful toys I keep in the studio.
I hope you'll enjoy it!"
