"Vintage Oberheim OB-X 8-Voice Synthesizer from 1979 with Encore Midi Retrofit - in excellent original condition.

This Oberheim OB-X is a 61 key, polyphonic analog synthesizer, featuring dual oscillators (with sync and FM), noise generator, resonant 12dB low pass filter, dual ADSR envelopes, an LFO, 32 presets, tape interface, and CV IO.

I’m a composer for TV, film and video games and I’ve used this OB-X extensively since I bought it the '90s…sadly I don’t use it like I use to and it’s time to pass it along to someone that will love it as much as I have over the years. I remember searching long and hard before I found this particular OB-X, I believe I’m the second owner…the first owner took exception care of it before I got it.


This OB-X is most likely a Rev1 built in 1979. Over the years I've seen folks replacing caps, resisters, mini trim pots, etc. on their vintage synths but this OB-X still has all the original electronic parts and components, works great and sounds incredible! The only mod that is the Encore Midi Retrofit that I had done back in the '90s…I’ve not replaced anything else since I bought it. The only thing not working is the led on the Noise "Half" Button selector that doesn’t light up when turned on, it was like that when I bought it.


The Autotune works great, especially after the synth has warmed up for about 30 minutes. The original eight voice cards are in tune all across the keyboard and sound big and fat - but if you want them all in pitch perfect tuning you could have a true synth technician/specialist to do a calibration-tuning on the all eight cards/voices. To me, a slight variance in pitch on the collective eight voices is how I remember these synths sounding from the 80s:)


I’ve kept it in my smoke free studio ever since I bought it in the '90s with a cover when not being used. The keyboard is really clean and great looking. The letters and screening are exceptionally bright and sharp. There are marks on the bottom, that's the way I got it (see photos) and a few small scratches on the external metal casing. The side panels are in great condition (not real wood but they look fantastic). Some of the screws look like they might have been replaced but they all look like what I think the original screws look like. The keyboard is in excellent shape, and all keys feel in top shape and work well with no glitching.

It comes with copies of the owner and service manuals."

Firstman/Multivox SQ-01

via this auction

You can find demos of the SQ-01 in previous posts here.

"Operation is very straight forward, but there is one incredibly unique feature: you can alter the waveform (and associated envelope shape) per step. Yes, it's essentially a "p-lock" 20 years before Elektron got there!

This unit has been completely serviced and calibrated (waveform volumes now match), and a diode put in across PSU input to prevent frying (PSU not included). PLUS it now had a custom non-volatile memory RAM board installed (no more batteries for pattern retention!)

It works a treat and sounds huge. Also has CV/GATE/CLOCK inputs, and CV/GATE/CLOCK/Sychro outputs, so easily able to be integrated into a modern modular setup."

Bronski Beat - Smalltown Boy (1984) Instrumental Cover

video upload by KOSmusic

"This is my version of an unforgettable great classic from the mid 80s: Smalltown Boy by Bronski Beat (of 1984).

I've always loved how this song starts with those pads and the DX7's signature harp... it always gave me goosebumps!! Furthermore, Sommerville's voice is truly fantastic with his unmistakable timbre.

I recreated the track by making some changes to the sounds and in particular to the management of the instruments, creating more stereo effect. I used the CS1x for brass, strings and synthesized trumpet. For the harp, I used the VST Dexed and the VST Jupiter-8 for the bass.

For the graphics of the video, I was inspired by the artwork of their first album 'The Age Of Consent'.

I hope you like the work I did on this track :)"

Korg Polysix: Inner workings

video upload by MIDERA

"Pulled out the Polysix - Always wonder whether I like it more than the Prophet 10. I'm strange. Something so simple about the Polysix that's just lots of fun. Relax - I probably don't like it more than the P10...

I guess the synth I like most is the synth that's sitting in front of me. Except the synths I don't have fun sitting in front of. I'm looking at you Roland D50."

Noisebug’s 4ms Sound-on-Sound System

"Running guitar through the 4ms Sound-on-Sound System, a Noisebug Exclusive! The 4ms Sound on Sound System was designed here at Noisebug to offer a small, compact sampling system that can be used in a variety of different situation, using a variety of different instruments. The Percussion Interface (PI) and PI Expander are a pair of Eurorack modules that generate gates and envelopes from acoustic drums, samplers, drum machines, and virtually any audio source that is plugged into its input, making this system a true sampling powerhouse! Next is the Stereo Triggered Sampler, a high fidelity, two-channel stereo sample recorder and playback module. The STS can record high quality stereo files, while simultaneously playing two different stereo files. A maximum of 600 samples can be loaded from the removable/swappable microSD card, in a variety of formats up to 96kHz/32-bit/stereo WAV. All sample parameters (1V/oct pitch, sample file selection, length, and start position) are CV controllable and can be controller directly from your incoming audio's amplitude using the envelope outputs on the Percussion Interface. Just to the right of the STS is the Dual Looping Delay. A modern looping devices grew directly from hardware digital delays of the late 70s and early 80s. A looping delay, modeled on units such as the classic Lexicon PCM42, has the very long storage times associated with dedicated looping, but without triggered record and playback functions. By default, a looping delay records and plays continuously, though recording can be suspended at any time with Infinite Repeat. Sustain of delays and loops is mainly accomplished with regeneration, allowing an organic, evolving approach to sound creation as new material replaces old, more or less gradually. The 4ms Dual Looping Delay also provides advanced clock input and output facilities that allow for locking delayed and looped material with sequencers and rhythmic devices. The final stage in this system is the Listen Four Quarters, a four channel stereo mixer with 1/4" (6.35mm) TRS balanced outputs and 1/8" (3.5mm) headphones output. Two mono channels with Pan knobs and two stereo channels with dual inputs provide optimal compatibility with both stereo and mono signals. The Listen Four Quarters can be daisy-chained to other Listen modules to create a larger mixer with sub-mix outputs.

video upload by NOISEBUG

"The D502 Multimode filter is based on the SSI2140 VCF chip. This chip has a unique stucture and gives it a different sound to most 4 pole filters.

You are able to select which of the 4 poles is fed to the output, giving you instant access to 4pole low pass, 3 pole low pass, 2 pole low pass and 1 pole low pass at the flick of a switch!

However it doesn’t stop there, you are able to make the first two poles into high pass poles, allowing all kinds of interesting filter topologies, for example you can easily get the following filter modes.

1 pole low pass
2 pole low pass
3 pole low pass
4 pole low pass
1 pole high pass + 1 pole low pass (1 pole bandpass)
1 pole high pass + 3 pole low pass
1 pole high pass + 2 pole low pass
2 pole high pass + 1 pole low pass
2 pole high pass + 2 pole low pass (2 pole bandpass)
2 pole high pass
1 pole low pass with special resoance drive
1 pole high pass with special resoance drive + 1 pole low pass (1 pole bandpass with a gnarly sound)"
