"Unique 'All-in-one' Vintage Synth. I purchased this locally from a hammond organ repair shop & brought it home, I was blown away by the accessible drum sounds & pattern based sequencing. Usually these type of keyboard is a "kids toy" but this was different, with the pure analog sounds piercing through my speakers, this thing busted through a mix with warm & 80's tones. The playable foot pedals are really fun connecting to the bass sounds. This is not only a collectors item with music history, but it's a playable instrument for synth wave, disco & electronic music producers & enthusiasts. The arpeggios & patterns spark inspiration & the drum sounds come in handy for even just sampling into a song manually if you are recording & only one to use one instrument for the entire song!
I've dived into this synth on many occasions & did the other night, so I know everything is in working order. I would recommend reading the manual since some of the standard workflow we are used to in 2025 wasn't normalized back then.
INCLUDEDS
- Synth, Original IEC Power, Cable, Keyboard Cover, 3 Soft Cases, Foot Pedal, Volume & Control Pedal
I have the original stand, but I have NOT INCLUDED it in the listing since it would add significant weight & size to the shipping. If you are interested, let me know!"

FOLKTEK ALTER Y GUITAR MULTI-EFFECTS PROCESSOR PEDAL
Note: links to listings are affiliate links for which the site may be compensated.
via this listing
Additional Signal Sounds listings
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

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."
