You can find demos and additional details in additional posts here.

"Manufacturer's description
Alter Y is the pedal version of Alter 2 eurorack module featuring four 1/4" jacks in addition to 1/8" as well as buffered switching that allows for trails.

Though it functions the same as other pedals, this pedal is a little different. Most pedals are made for guitars and then artists may choose to use them in different ways. We made this pedal to work with either standard ¼” jacks (for both input and output) or 1/8” (3.5mm) jacks for use with anything else. For those who like to use CV (control voltage) for any eurorack format, cv keyboard, or pedals which output cv (eg. expression or sequencing), all four of the main knobs have cv inputs (mix, x, y, filter) so you can control your knobs without touching if the desire strikes you.

These pedals accept guitar, line or eurorack levels.

The enclosure is very thick, gold plated PCB (it’s very, very tough).

Included power is standard for most pedals (2.1mm, -tip)

We wanted a broad array of effects in each X and Y pedal so each is a mashup of effects which we thought complimented one another when used together. Running X into Y or vis versa creates some powerful changes."

"This unit was fully overhauled, sparing no expense, a process requiring 26 hours of skilled pro vintage synth tech time. This included future-proofing measures that will hopefully extend its life way beyond others. The value of this labor plus parts is of course factored into its price. This is a rare opportunity to purchase a gorgeous JP-4 that's working perfectly and that should make its next owner very happy."

Oberheim DSX Digital Polyphonic Sequencer SN A42406

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

via this Reverb listing

"In the dark ages of synthesis, before midi, the questions of sequencing and programming had yet to be answered. A feature folks wanted to have but had yet to be invented. Leave it to the big brains at Oberheim to come to our rescue!

The DSX was released as part of the proprietary Oberheim Parallel Buss system. This allowed users to connect the OB-8, DMX drum machine, and the DSX allowing for easy control and syncing of synths. In addition to controlling these synths, the DSX features 8 CV and Gate outputs to control up to 8 more other analog synthesizers!

The DSX records in realtime the notes and patch changes you create while playing your OB-synth. It can hold up to 6,000 notes! The DSX can store up to 10 different sequences/songs. Each sequence can have 10 polyphonic tracks for multiple OB-synths and DMXs. Patch info including splits and doubles can be stored too. Quantizing, looping, editing, transposing, and sequence merging are a few more features. If you've got any of these classic (pre-MIDI) Oberheim analog OB-synths lying around, the DSX is an easy way to directly control them in a classic way, and without any need for MIDI retro-fits or interfaces."

"Super cool OG programmable drum machine! Classic 80's vibe. Works! The box has duct tape on the corners to hold it together (before my time) and the battery pack is broken but the white electrical tape does the job. Can also run off a 6v adapter.

Overall in great condition, one of the screws on the backplate is stripped but it's included in the box."

ARP AVATAR Synthesizer odyssey RESTORED only CV gate control

Additional Tone Tweakers Listings

"Meticulously refurbished over approximately 22+ hours to be as good as it could possibly be, with a new set of modern faders that are way better than the originals and their copies, this unit is a real pleasure to play and is fully functional, with one exception - we disabled the guitar interface. This unit can still be controlled via CV and gate.

Why did we disable to guitar interface? This unit, like most, did not come to us with the guitar pickup and cable, so we weren't able to test it with a guitar. That said, the guitar interfaces are usually broken and beyond repair at this point. The manufacturer sealed the interface circuitry in epoxy, so if (and when) a component inside that black epoxied box goes bad, as they almost always do, they're impossible to open and repair by practical means. Also, even when the guitar interface is working, you'll need the pickup and cable, which have often disappeared over the decades. So, if you're looking for a unit that will work with your guitar, this one won't, and it's likely many others won't either, based on what we've seen - please search our listings to see if we have another in stock that does. This one contains the same synth engine as the ARP Odyssey Mk3 (with a couple very minor differences in the modulations) and can be controlled via a midi-to-cv converter or compatible vintage keyboard or sequencer. Be careful if you're considering buying one of these elsewhere - most sellers don't test them properly and don't know enough or care enough to identify and report problems, especially with the guitar section. Any avatar or odyssey that still has its original faders will almost definitely need them replaced, so consider that too. And then there are the ones that use the low quality copies of what were already low quality original faders. We already did this work, and it's expensive. Cost was around $300 for the new faders, plus additional parts, plus 22 hours of skilled labor, plus additional labor to route the sample and hold mixer output to modulate VCO2 and the filter for oscillator and filter FM as you'd have on an Odyssey (which is being performed as I type this so I don't know the total time yet)."

Roland Juno-106 61-Key Programmable Polyphonic Synthesizer w/ New Voice Chips

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

via this Reverb listing

"The Juno-106 synthesizer was Roland’s successor to the Juno-60 and was first released in 1984. It was one of Roland’s first synthesizers to include MIDI and the patch memory was expanded to 128 patches over the 56 available on the Juno-60.

The synth is polyphonic with 6 voices and 1 digital controlled oscillator per voice. It has a chorus effect to fatten up the sound and by pressing both the Poly 1 and 2 switches at the same time, the synth can be played in monophonic unison mode with all 6 voices playing on every key pressed. It has a non-resonant high pass filter and a resonant low-pass filter.

It’s easy to program and remains a popular synth to this day.

This unit was fully serviced in Oct 2021 at Bell Tone Synth Works and at that time, all 6 voice chips were replaced with Analogue Renaissance voice chips. In addition, they performed the following services:

Replace 3 electrolytic smoothing capacitors in power supply, reflow solder on power transistors/regulators, adjust power supply rail voltages
Re-solder output board jacks, cleaned output level switch and tuning pot.
Clean volume pot, portamento pot and pitch bend pot.
Replace old soldered-in patch memory battery with new battery in battery holder for easy replacement in the future; reload sounds.
Calibrate all parameters to Roland specs.
Replace 2-prong Japanese power cable connector with standard 3-prong IEC C14
Replace all panel button tact switches, clean all sliders, replace crumbly slider dust gaskets with new ones.
Replaced (2) MN3009 BBD IC's in Chorus circuit with new Xvive MN3009s to reduce noisy wooshing
Repaired and re-centered bender pot by resoldering the wiring and re-aligning to get the bender working correctly."

Manufacturer's description
A MIDI Four-track, Sequenced Arpeggiator, Chord and Drone Player

We’ve turned complex music theory into a killer synthesizer jamming MIDI controller.

Whether noodling in your music space after work or jamming with friends, The NDLR can take your music to amazing places!

Press one of the seven chord buttons, and the two arpeggiators and drone follow the chord notes while your polyphonic synth sings with pads.

There are start and stop buttons for each of the four parts, and a button to start/stop all parts. And there’s a “panic” button to stop all MIDI notes.

"We fully disassembled, cleaned and serviced this unit the way we typically do with our high end vintage synths, in an effort to make it as good as it can be. This restoration took 12 hours of highly skilled vintage synth tech time, plus parts costs. The high value of this work is of course factored into its price that should be considerably higher than that of cranky unserviced or minimally serviced examples on the market."
