No mention if that keyboard comes with it. Anyone know more about it? Looks like an extremely well done DIY job.

Update via vco2vcf2vca in the comments: "Moog Matriarch Dark version, apparently also for sale..."

Curious what happened to the front panel.  Pic of a production model below via this post.

This is a Juno-106 but for the home enthusiast (HS meaning “Home Synth”) as it’s equipped with two speakers and a sheet music stand. All six voice chips have been replaced as well as a modern 3-prong power outlet installed. The speakers can be disabled by plugging a cable into the headphone output. This also has a stereo input so you can run a drum machine into the internal speakers/output."

Exploring 2 Welson Stereo Symphony !


video upload by Vintage Audio Institute Italia

"Welson Stereo Symphony - sometimes called Welson Stereo Orchestra.
A rare, Italian string machine from the mid 70's with brass, trumpet, Piano and Harpsichord presets and multiple panning controls.
We just got two of these back from repairs so thought we'd make a comparison video.
To our ears they sound very similar, as should be, but some presets do differ a bit.
This could be because of ageing components and calibration, or the fact that only a small number of these were ever made, at least compared to the Solina String Ensemble or Logan String Melody, and small production runs don't have the same consistency as the large ones.
Volume and sustain controls for each presets at the split point, maybe a bit excessive but anyways - this is a great sounding instrument in our opinion.
Playing around with the preset and Orchestra pan options gives you a wider range of sounds than your normal string machine."

FAT Freebass FB383

"monophonic analog clone of the TB-303. The FAT Freebass FB 383 was made under licence by MAM and is a version of the MB 33 with a special front-panel design as part of an exclusive deal with Turnkey music shop UK - which is where I bought it originally. The FAT Freebass FB383 offers all the same basic sounds and controls as the original TB-303 in a 1-unit rack module. There are 8 basic knobs for the same basic 303-like control: tune, filter cutoff, resonance, envmod, accent and decay. Unlike the 303 however, the oscillator can be controlled from sawtooth to square from one of the knobs on the front. There is also an external audio input to the filter for processing other sources and a dipbutton control to select the MIDI channel. On the front there is a power on LED, a MIDI activity LED and an auto tune button."

Synthesizers.com unfinished Entry System 2006

"Back in 2006, Synthesizers.com offered a "pay-as-you-go" Entry System plan: pay upfront they shipped you a 22-space cabinet and a handful of modules, and then for $120/month they'd keep sending you new modules. I got 6 modules in and lost interest, but I held onto the system for 15 years.

Recently I took the time to dust off the modules and re-rack them in a carpeted 19" 5U rack that fits all 6 of the modules and PSU in a more... approachable form factor. It's still very heavy, but much easier to lug around than the original MDF cabinet. This is a complete synth voice, including:
Q104 MIDI interface
Q106 Oscillator with PWM, linear and exponential FM, and simultaneous sine, triangle, saw, ramp, and pulse outputs
Q108 VCA with switchable linear/exponential response and inverted output
Q124 Multiples (passive)
Q109 Envelope Generator with adjustable ADSR segments
Q107 State Variable Filter with 1V/oct and linear FM, CV over resonance, a two-signal mixer, and simultaneous outputs for high-, band-, notch- and low-pass modes
The PSU is also way overpowered, as it was intended to run nearly 4x the modules (22 instead of 8), so it would be possible to build up or down with additional 5U racks. (This one is the Procraft 5U rack at 9" depth from Pro Speaker Parts, which can be had new for $71.50 as of this writing.)

Comes with 8 heavy-duty Synthesizers.com patch cables and and 8 light-weight Hosa patch cables, which is more than enough for this setup. I'm listing this as excellent because it is in great shape for its age. The only thing "wrong" with it is that some of the panel screws are a bit rusty. They're easily replaceable and don't affect the unit at all."
