"The OB-Xa was released in December 1980, a year after the OB-X was released. Instead of discrete circuits for oscillators and filters, the OB-Xa (and the Oberheim synths to follow) switched to Curtis integrated circuits. This made the inside of the synth less cluttered, facilitating troubleshooting, and reducing the cost of manufacture. It was getting more difficult to service the OB-Xa due to the scarcity of Curtis chips; however, Curtis started re-manufacturing some of these chips in June 2016,[3] which has breathed new life into the longevity of the OB-Xa and many other synthesizers that use these chips. There are a couple of knobs missing but everything works really well and it sounds like a dream." DE10457

"All functions work great and has new keyboard bushings. Missing handle strap and has a little chip in the right lower part of enclosure (see pic)
This synth sounds enormous due to 4 oscilltor layout, ring modulator is also very sweet."

Casio VZ-10M - Exploring the Synth and Sounds

Published on Jul 4, 2019 ProckGnosis

"And here is a verrrry long video covering the Casio VZ-10M, including listening to a lot of patch examples, looking at how Casio implemented the phase modulation engine, and looking/listening to the basic waves and some phase-modulated waveforms available for programming.

Organization of the video is as follows:
00:00 - Casio VZ-10M ProckGnosis Theme Song (in 9/8)
00:30 - The Introduction
02:50 - Sound and Commentary
11:47 - How the VZ-10M Makes Noise (big explanation)
18:12 - More Sounds, Less Commentary
28:23 - Phase Modulation Analysis (M1 modulating M2 with different waves)
31:04 - Even More Sounds, Some Commentary

As I say in the video, the Casio VZ-10M has a lot of similarities to the Yamaha DX7, including the synth engine and how the modules are worked with like operators, but it also has some other tricks the DX7 doesn't. This includes having saw waves instead of just sine waves to phase modulate and phase modulate with, as well as being able to ring modulate the partner module.

The synth isn't great, but it is extremely interesting to work with, and it can produce some interesting sounds. When the big brother keyboard (VZ-1) was released in 1988, it was Casio's flagship synth. It's curious why Casio would have opted to produce something that, in so many ways, was similar to the already well-established DX7 and all the variants, and even sounded fairly similar.

I think it would have made more sense to release a "Super CZ" with 16 note polyphony, a phase-distortion engine, and the ability to layer, split, and fade similar to the VZ. It's possible even a "Super CZ" wouldn't have sold though, as it seems folks were just more fascinated by more realistic sounds like those offered by the Roland D-50 (released in 1987) and the Korg M1, also released in 1988 for about the same cost.

As I said in the opening of the video, I think the video could have been better organized, and better split over 2 videos, but I’m running short of time and figured it was better to just get it out."

Vulcan Modulator AND Mindmeld Companion Eurorack Modules

via this auction

"Livewire Vulcan Modulator with attached Intellijel Mindmeld companion Eurorack modules. Basically mint!

These are now-unavailable modules in very clean 100% working condition (obtained new from Analog Haven in 2010):

The Vulcan is a dual VC LFO (that can go fair way up into audio range) with individual multiple waveforms and mixed sum, diff etc outputs.

The Mindmeld is a companion module giving frontpanel access to switched (replacing the Vulcan's back-panel jumper options) waveform combos - also allowing you to inject an ext signal into each situation. Also inputs to reset the Vulcan wave periods.

This combo is a nice hands-on path to some exotic looped voltage contours."
