WMD Skorpion Sound Demos

video uploads by WMDevices

"Skorpion is an 8-stage vector based wavefolder module that boasts a huge range of sounds via it's deep, yet intuitive set of controls. In this video, we cut about an hour of jamming and experimentation together into about 8 minutes of sound examples. No talking in this one, just pure sonic exploration and a demonstration of what this module can do with a simple input.

In the intro, we're running a sine wave through Skorpion and add some CV from an envelope into slope to create some rhythm. We add some drums to hear this in context with a drum beat. We then transition into a sine wave as the input signal, then some Saw (with windows) and Swarm Waveforms, experiment with a filter before the Skorpion, and end up back with some drums in different configurations.

WMD designs electronic hardware for musicians longing for a balance of precision and exploration. Our quality control is the absolute finest, with service to match."

The Prophet VS was the last synthesiser to be released under the Sequential Circuits name. After the takeover by Yamaha in 1987, the following synthesisers were released under the Yamaha name.

Here is a demo track only made with the Sequential Prophet VS vector synthesizer from the year 1986. I use only self programmed sounds and the internal arpeggiator.

Sequential Circuits' last synthesiser in the 1980s was the Prophet VS, a hybrid synthesiser that was launched in 1986. It was the last synthesiser developed by Sequential Circuits before the takeover by Yamaha.

The Prophet VS was a digital synthesiser that differed from the company's previous analogue models. It was based on vector synthesis, a technique that made it possible to mix between different waveforms to create complex and versatile sounds. Although the Prophet VS was a digital synthesiser, it included a number of features that set it apart from other digital synthesizers of its time, such as its ability to change and manipulate sounds in real time.

Future Retro Vectra Prototype with Black/Gold Faceplate SN 0001

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

via this Reverb listing

"One of only 2 known Vectras with an early Black/Gold faceplate which was never put into production. No Black Gold keyboards were ever made as far as I know. These were prototypes. This unit is fully working with all mods and upgrades including a firmware upgrade to version 2. Includes box, packing, manuals, and Universal power supply. The other known unit has purple heartwood endcaps and ALSO features a 001 serial number. These are the only units like this known to exist. Will be double boxed for safe delivery worldwide.

The Vectra is a unique hybrid synthesizer with a flexible architecture that allows many different forms of synthesis to be realized. It’s the best of both worlds… The Vectra utilizes digital oscillators, ring modulators, noise sources, vector mixer, LFO’s, complex envelopes, and modulation routings providing many capabilities that would be very difficult to produce with analog circuitry alone. This allows for accurate tuning, repeatability of complex patches, and patch storage. The Vectra also provides a multi-mode analog filter, VCA, and final output, as these provide the best sonic qualities."

WORNG Electronics Quiver LFOs

video upload by WORNG Electronics

"Four analogue LFOs drive the modulation of Quiver, with cycle times varying from 33ms to over 35 minutes. They're controlled with a Rate macro and CV, and the three slowest LFOs each have an additional CV control for further control. This patch demonstrates the various LFO outputs by modulating the cutoff of a Parallax filter."

Quiver Analogue Modulation Toolkit

Quiver is a 100% analogue patch-programmable modulation powerhouse. Quiver’s 16 input, 18 output interface contains:
- Four triangle core LFOs with macro control, individual CV control, and cross
modulation
- Analogue wave folder/saw phase shifter
- Full wave rectifier
- Analogue noise source
- Voltage comparator
- Sample and Hold
- Analogue Min/Max
- A three input, six output Modulation Cube based on the acclaimed Vector Space
circuitry
‍
When left unpatched the different processors flow from one to the next with cleverly designed normalling, giving 18 modulation sources to use throughout your system.
‍
Quiver is the perfect quiver of essential modulation basics to get your modular system started, or to add a high quality, fully patchable, modulation workstation to your existing system.
‍
When designing Quiver we asked the question 'What collection of CV processors can greatly expand the capacity of every modular system?' and then carefully chose normalled connections and added four analogue LFOs to drive them. The result is like a mini modular system in itself, creating complex evolving modulation that never repeats, but is able to be quickly reconfigured with a patch cable or two.

Sequential Prophet 10 REV4 versus Prophet VS Vector Synth: A not-so-detailed comparison and thoughts

video upload by MIDERA

"I had both of these side by side and figured it was now or never - do a brief comparison of the two head to head. What's interesting is listening to the Prophet VS filter afterwards it didn't sound so 'TB-303' like as it did when I recorded it. It sounded more tame. It was a bit depressing, but I guess that's part of what is important to hear - differences between what's recorded and what's heard live.

A few notes: if you listen on a phone, you really won’t hear ANY differences mention, lol. I don’t hear the aliasing on the PVS.

You can initialize the PVS patch as well holding enter and pressing zero. I didn’t do that here because it puts all 4 oscillators on using different waveforms, which isn’t really initialized for my purposes.

Also - I want to comment about something that annoys me. If I ever want to look up anything on the "Prophet VS" it comes up as thinking it means 'versus' so I hardly find any information about the VS.

What do you think about the two (P10 v PVS)?
