via this Reverb listing

"The mighty powerful DSI Pro 2. I replaced the keyboard with eurorack rails to take advantage of its cv I/O and sequencer. Expands both the pro 2 and your eurorack exponentially and can do some pretty cool stuff!

I fastened a deopfer passive psu bus on the base of the key bed and have been powering with an external linear supply but could be powered just as easily with euro psu (tiptop uzeus etc)"

Currently listed on Reverb and eBay here.

Pics captured here.

"functionnal demo of this Wersi Wersimatic analog drum and accompaniment unit I just serviced. It's very like other units of that era like the Elgam Carousel, Elka Wilgamat or Godwin Drummaker.
You get 24 rhythm patterns that can all be combined and 12 accompaniment patterns that can also all be combined and these consist of an arpeggio (with a selection of 2 sounds: piano and spinet), a walking bass and a chord (with a selection of 3 sounds: piano, spinet and guitar). You can manually play chords or play 'one-fingered' chord and then you have the option to alter the chords (Min, 7th and Diminished).
On the drum you have the option to alternate 2 patterns. Note that one of the pattern should have a dot under its name and the second should not, otherwise these pattens won't alternate but combined. You can actually alternate between groups of combined dotted patterns and undotted patterns (i do this towards the end of the video).
Other nice features includes mute switches for most of the sound (unfortunately not for the Hi Hat and Cymbal), snare roll, drum fill, stereo output (demo was recorded in mono output plugged into a Dynacord VRS23 for reverb).
These units can also very easily be moddified (indivual outputs, trigger input, clock input etc)"

Akai Ewi 1000 Signed by Mike Brecker?

Note: Auction links are affiliate links for which the site may be compensated.


via this Reverb listing

"Akai EWI1000 (First-Generation Controller) — Signed by Michael Brecker / Provenance: Montreal Jazz Festival 2001

Model: Akai EWI1000 controller only (no sound module). Condition: Overall good; strap hook has some rust from a past strap modification but i prefered to not touch it. Special Value: Genuine “Mike Brecker” autograph sealed under protective film since 2001; still clear and intact today.

Rarity & Provenance
“To my knowledge after extensive research, this is the only Akai EWI ever held and signed by Michael Brecker. No other examples have surfaced in autograph collections, auction archives, or collector networks. That rarity adds powerful uniqueness and historical weight to this instrument.”

“This is not a generic EWI1000. It is the specific instrument Michael Brecker held and signed for me in July 2001 at the Montreal Jazz Festival; he even ‘air-played’ it for several minutes before signing ;) . The signature has been preserved under film since that night.'"

via Wikipedia: "Michael Leonard Brecker (March 29, 1949 – January 13, 2007) was an American jazz saxophonist and composer. He was awarded 15 Grammy Awards as a performer and composer, received an honorary doctorate from Berklee College of Music in 2004,[3] and was inducted into the DownBeat Jazz Hall of Fame in 2007."

Roland Jupiter 6 61-Key Synthesizer w/ Wood Side Panels & Bass Mod

Note: Auction links are affiliate links for which the site may be compensated.


via this Reverb listing

"A beautiful wild and unique synthesizer that is hard to come by these days!

This was recently serviced and given a general tune up and upgraded with walnut wooden side panels.

It has some cosmetic wear with some rough spots on the paint of the body and a small inward curve on the back panel but overall is in great condition for its age and functionality is flawless.

This also has had the Florian Anwander resonance mod done so that the bass doesn't fade with the resonance up making this an excellent bass synth with different resonance sequences."

Waldorf Microwave XT w/ Custom Black Overlay

Note: Auction links are affiliate links for which the site may be compensated.


via this Reverb listing

"Ticks all the boxes - 30 voices, reskinned with striking black theme, extra overlay, upgraded Kilo knobs (currently $10 or more *each*), power supply.

Oh yeah, and it sounds amazing as well. If you're looking for an old school Waldorf wavetable sound, this is your best choice. Still classic sounding, but with a lot of modern touches.

Fits in a rack, looks great on a coffee table, can be safely lugged to gigs. I have 2 and still debate keeping this one."

"Octave Plateau Voyetra Eight Rev 4

(Only Rev 4 has MIDI and Aftertouch)

Professionally serviced by Mystery Circuits in 2025, this is ready to go for several years before another service.

Only cosmetic defect is rack ear has some paint chipping. Otherwise this in fine confition, easily Excellent for a mid-1980s beast.

Watch the YouTube video--it's of this actual synth and without any processing (dry)."
