V.A.I. 55 Elka Wilgamat / Multivox MX-3000

video upload by Vintage Audio Institute Italia

"Another spin with these twooddbalss: The Elka Wilgamat and Multivox MX-3000.
The Elka Wilgamat is probably a bit familiar to our viewers by now - an Italian auto-accompaniment machine with three sections:

1. Analog drum machine section
2. Bass section with 2 sounds and variations
3. Chord section with 3 sounds

Harmonically controlled by a two-octave keyboard with a fill-in bar on top, it has a great warm sound that's unmistakably mid-1970s to our ears, the drum machine alone sounds great.

The Multivox MX-3000 is a pretty rare Japanese string machine and monophonic synth combo.
A bit similar to the Farfisa Soundmaker or maybe Solina String Synthesizer (the BIG one - not the regular String Ensemble) or the Crumar Composer but with a more complex polyphonic - or rather Divide Down - section.
Lots bells and whistles here.

It basically has three separate sections:

1. A bass synth section with multiple preset sounds and attack, decay and tone controls.

2. A polyphonic section with preset sounds that are modifiable in quite a few ways with a very nice and aggressive filter section, attack/decay, two different choruses, two glide modes and more.

3. Single Oscillator monophonic section. No presets but a few different wave forms, a very nice filter, portamento and the usual mono stuff for great leads, basses and even some space effects.

The Polyphonic filter and choruses are very cool on these, maybe that's what we got it for initially but it's turning in to our desert island machine, there's really a lot going on here, it's a versatile instrument with quite a unique and somewhat rustic sound.

They're famously hard to service due to lack of a good set of schematics.
The build-quality is strangely bad for late 1970s Japanese keyboards so they somehow always break down.

New Patch Presets for the Roland JX-3P Synthesizer!

video upload by SynthaTone

Note seeing a link for the patches. Check with SynthaTone on YouTube if interested.

"Roland JX-3P Organ, Pan Flute, Saxophone and Brass Section preset patch demo. These patches are examples from a soon-to-be-released sound set that will be available at an affordable price.

These patches can be loaded into a stock JX-3P from a cell phone headphone jack to the input jack of the Tape Memory interface on the back of the synthesizer. An old phone that you have but no longer use makes a great dedicated storage device that you can always have hooked up for easy access. This is a good workaround if your JX-3P has a dead battery and you want to load sounds until you get the battery replaced.

These patches can be programmed manually into a Kiwi-3p KiwiTechnics or River Creative Technology (Organix) modified unit or a Roland Sound Cloud ACB VST instrument using the included data chart decoded from the tape memory audio file.

The JX-3P has a 3rd memory bank with 16 additional presets in the Service Mode. This memory is shared with the Sequencer and is overwritten when a sequence is written. However, if you write a short sequence of no more than 32 steps, it will still be there after you write patches into the 3rd memory bank.

Service Mode is accessed by pressing and releasing the Tape Memory button, then while pressing and holding patch button 4, pressing and releasing the Tape Memory button again. An alternative method is to press and hold patch button 4 when the JX-3P is switched off and then switching it on.

The JX-3P factory presets only hint at the sonic possibilities of this instrument. With the same basic sound as the Jupiter 8, I have found that the JX-3P's only real limitations are the shared envelope generator, and lack of a 2' pitch for the oscillators even though there is a button available for it, something that is found on the Jupiter 6 and Jx-8P. There are workarounds to these limitations that can still enable the creation of fun-to-play sounds reminiscent of the Yamaha DX7 and the Roland D-50. I have come to believe that the JX-3P really should have been named the JX-6, with the JX-8P designated JX-6A or JX-8 if it were upgraded to 8 note polyphony.

The soundtrack for this video was produced in Reaper with the plugins MT Power Drum Kit 2 for percussion and Sanford Sound Design Reverb for ambience. The JX-3P was recorded live in monophonic audio. The music is an original composition."

"8 note polyphonic synthesizer. One of only 2000 manufactured in the early 1980's, if you are interested in this one you will most probably know much more about them than me however you can read all about them if you click . The link will take you to a 27 year old article in Sound on Sound which refers to the value of a used Chroma at £1,500, those were the days, to put things into perspective a German owner recently advertised a faulty one on eBay at £15,000 so our valuation of £7,000 for a fully working model seems exceptionally fair. No offers please.

The Rhodes Chroma was never fitted with Midi during manufacture but it was possible to fit a Midi modification. When this one came in it had a fault which was caused by the Midi mod which no longer worked, during the service of the Chroma Adrian removed the faulty Midi kit and made other repairs so it is now 100% however the non-functioning midi sockets are still fitted to the unit."

Tom Oberheim on GForce OB-E

"'I was pretty amazed by OB-E, it was pretty damn close right out of the shoot. It was “wow!'. I like listening to that." Tom Oberheim.

In 2021, during the release of OB-E®, we were contacted by Marcus Ryle on behalf of Tom Oberheim. Marcus is a co-founder of Line 6® but also a former Oberheim Developer who contributed to the OB-Xa, DSX, DMX, OB-8, Xpander and Matrix 12. Via Marcus, OB-E had found its way to the ears of Tom Oberheim and they were both impressed enough to suggest a collaboration to refine the instrument and release an update carrying their full endorsement.

Working under the guidance of Tom and Marcus, we further enhanced OB-E, Refining the Detune feature and adding a new Vintage knob, which dials in more realistic musical inaccuracies in line with the original instrument for a truly authentic 8-Voice experience.

The 8-Voice is not simply eight identical SEMs put together. The interaction of those 8 independent, and slightly different Synthesizer Expander Modules, plays a major role in making the 8-Voice’s sound special and the injection of these authentic inaccuracies into each of the eight SEMs in OB-E takes it to another level.

But don't listen to us - listen to two of our heroes, and bonafide industry legends, talk about their opinion of OB-E.

1979 Oberheim OB-X 8-voice Vintage Synthesizer w/Midi

via this auction

Pic of the inside below.

"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."

Acids Neurorack - The First Deep AI-based Eurorack Synthesizer

video upload by Acids Team - Ircam

Note Artisan Electronics has a Neurorack module system (4:52 here), however it does not appear to be AI based. There is also this user labeled Eurorack system with "brainwaves/EEG signals as source of modulation (the Neuro portion of it)", but again no AI (there is also soundmachines' BI1brainterface (no AI). (Update: there was also the Hartmann Neuron and Jomox Neuronium, both based on neuronal networks.) As for AI applied to synthesis in general, you can find posts mentioning artificial intelligence here. I believe the earliest reference would be John Chowning in 1964: "Following military service in a Navy band and university studies at Wittenberg University, Chowning, aided by Max Mathews of Bell Telephone Laboratories and David Poole of Stanford, set up a computer music program using the computer system of Stanford University's Artificial Intelligence Laboratory in 1964."

Description for the above video:
"The Neurorack is the first ever AI-based real-time synthesizer, which comes in many formats and more specifically in the Eurorack format. The current prototype relies on the Jetson Nano. The goal of this project is to design the next generation of music instrument, providing a new tool for musician while enhancing the musician's creativity. It proposes a novel approach to think and compose music. We deeply think that AI can be used to achieve this quest. The Eurorack hardware and software have been developed by our team, with equal contributions from Ninon Devis, Philippe Esling and Martin Vert."

Motivations
Deep learning models have provided extremely successful methods in most application fields, by enabling unprecedented accuracy in various tasks, including audio generation. However, the consistently overlooked downside of deep models is their massive complexity and tremendous computation cost. In the context of music creation and composition, model reduction becomes eminently important to provide these systems to users in real-time settings and on dedicated lightweight embedded hardware, which are particularly pervasive in the audio generation domain. Hence, in order to design a stand alone and real time instrument, we first need to craft an extremely lightweight model in terms of computation and memory footprint. To make this task even more easier, we relied on the Nvidia Jetson Nano which is a nanocomputer containing 128-core GPUs (graphical unit processors) and 4 CPUs. The compression problem is the core of the PhD topic of Ninon Devis and a full description can be found here.

Targets of our instrument
We designed our instrument so that it follows several aspects that we found crucial:

Musical: the generative model we choose is particularly interesting as it produces sounds that are impossible to synthesize without using samples.

Controllable: the interface was relevantly chosen, being handy and easy to manipulate.

Real-time: the hardware behaves as traditional instrument and is as reactive.

Stand alone: it is playable without any computer.

Model Description
We set our sights on the generation of impacts as they are very complex sounds to reproduce and almost impossible to tweak. Our model allows to generate a large variety of impacts, and enables the possibility to play, craft and merge them. The sound is generated from the distribution of 7 descriptors that can be adjusted (Loudness - Percussivity - Noisiness - Tone-like - Richness - Brightness - Pitch).

Interface
One of the biggest advantage of our module is that it can interact with other synthesizer. Following the classical conventions of modular synthesizers, our instrument can be controlled using CVs (control voltages) or gates. The main gate triggers the generation of the chosen impact. Then it is possible to modify the amount of Richness and Noisiness with two of the CVs. A second impact can be chosen to be "merge" with the main impact: we will call this operation the interpolation between two impacts. Their amounts of descriptors are melt to give an hybrid impact. The "degree of merging" is controlled by the third CV, whereas the second gate triggers the interpolation.

Steve Fisk's 1976 ARP 2600 with 3620 Keyboard SN 0732 ?

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

You can find a demo by Steve Fisk at the 2011 PNW SynthFest demoing his ARP 2600 posted here (see this post for additional videos of the event). P.S. If you aren't familiar with Steve Fisk, see this Wikipedia article. His Yamaha CS60 went up for sale back in 2013. According to this auction by Salamander Labs, his 2600 is up for sale. I have no way of verifying, so do your due diligence if you are interested. Note in the video linked above there is a green monkey sticker on the front panel. It's missing from this ARP 2600 but you can see a slight discoloration where it would have been. As always, who knows...

Details via the listing:

"Ok, this is it. An Arp 2600 with keyboard used extensively as a live and studio instrument by Steve Fisk, whose comments and the unit’s pedigree are below. This instrument has been used on the road internationally, in studio, and live performance settings, and as a result has some cosmetic scratches. The power supply caps, speaker amp driver transistors, key bushings, and a few key springs have been replaced…and the shittyist plug ever used for a keyboard has been replaced as noted below….otherwise it is original. It is fully discrete, and the circuit boards are NOT epoxied so it can be serviced. A full factory calibration was completed by Gemma at Sound Audio Repair in Olympia, Wa…"

"From Steve Fisk;

My 2600 is the first synth you see on the Arp 2600 Wikipedia page. I am the original owner. I bought the synthesizer in 1976. It was my primary instrument for years. I wrote and performed several noisy live pieces with the ARP. It was also my “jam” instrument for many improvs in Olympia and Seattle in the late 70’s. It was a key part of my live setup for Pell Mell, Pigeonhed, Customer Service, and Tiny Holes. It is also featured in much of my studio work with Pell Mell, Soundgarden, Pigeonhed, Reggie Watts, Unwound, Some Velvet Sidewalk and Seacats. The beast was my goto box for 808 kick drums(see Soundgarden’s “Spoonman” remix). It also did duty on several film soundtracks and corporate work. In 1995 the Jones plug that connected the keyboard to the main frame was replaced with a robust milspec connector by Omega Intl, a vintage synth service run by an ex roadie from the Moody Blues. It is in excellent working order despite some well earned cosmetic blemishes. I’m going to miss the spring reverb, a great resource for sound effects."

[Kawai S-100F] 40 yo japanese beauty gets intense cleanup & service

video upload by Synthfluencer

"In this video I show how I cleaned and serviced the Kawai Synthesizer-100F. The 100F is a mono synth from the late 70s. It has one oscillator with sawtooth and square waveform, white noise (that can't be mixed), two envelopes and a LFO speeding up to audio rate, a lowpass and a highpass filter. The lowpass filter can be modulated by LFO, envelope and waveforms that gives pretty unique sound design possibilities.

The unit was very dirty when I purchased it. Almost all faders were banged, resonance didn't work at all. I decided to give it a deep clean-up and a fresh calibration. I didn't want to do a makeover but rather bring back the vintage beauty of this wonderful synth without removing all of its patina.

Background music was made usind the 100F among the Vermona Synthesizer, Yamaha CS-5, Waldorf Streichfett, Behringer Deepmind, Model D & Neutron and Elektron Model:Samples.
