Click here for additional Wavolver posts by O.Z. Hall.
"The Wavolver II is a waveshaper that includes both a wave (manual) folder and a pulse waveshaper (with vertical offset and pulse width modulation ). It also includes a second pulse wave. This Eurorack module is available from Elby Designs. The circuit was designed by Ian Fritz.
I'm modulating is with a quantizer which is acting as a kind of sample and hold circuit."

"An updated version of Roland's infamous VT boxes from the early 2000s, this time as part of the Aira family. With a built-in vocoder, pitch correction, and harmony engine this portable box leaves little to be desired."

"Synergy DKII+ rare vintage digital synthesizer made by Digital Keyboards in New Jersey in the early 80s. It has a super valuable programmer upgrade that stores 24 preset cartridges internally which you can load as banks right from the front panel. No need for the actual cartridges with this one as it has the massive preset library onboard.
Also included is a working Kaypro 2 computer for essential deep programming of the instrument.
If you are reading this, you likely know what these are and their historical significance in the FM canon."

Synthesizers.com Studio 66 Mid 2010's - Walnut

"A beautiful Synthesizers.com Studio 66 Modular Synth with a KB15 Dual voice keyboard. I am the second owner and have had it in my studio since mid 2021. I will be downsizing my studio, and as a result, have decided to sell most of my synth collection. Please be sure to check other my other listings.
The walnut cabinet is in great condition - the very top of the smaller cabinet has some marks where equipment was stacked on it from the previous owner. (This can be seen in the video below) - It could easily be buffed out. Modules are in great shape, as is the keyboard. Price for a new one of these with a keyboard and shipping approaches $15,000!"

New England Digital Synclavier II

"Synclavier II stereo 16 voice FM synthesizer in very good condition. The package comes with the ORK keyboard, the floppy drive with the boot up disc, the Winchester hard drive with loads of sounds, a Kennedy tape drive for sample to disc, a sample to disc module, the Apple Mac computer running the termulator software, and factory owners manuals.
I have always been fascinated by the lore of this instrument. It has definitely held up to its legendary history - it is capable of sounds unavailable anywhere else and is really fun to explore.
Now, the fine print: I bought this instrument in April, 2021 as a fully functional 16 voice FM system, and it works flawlessly. The unit comes with a sample to disc module, and tape drive to sample to, BUT the current operating system DOES NOT support those features. I am also selling a Synclavier VPK keyboard on a separate listing because it is not supported on this software release. There is plenty of support for this instrument, and obtaining an updated software release should be very easy, I just have not pursued it as I am downsizing my studio and need to sell most of my collection. Just keep in mind that while this Synclavier comes with these added features, you are buying a 16 voice stereo FM synth. It is being offered at the price that I have invested, so keep that in mind if you want to make an offer."

You can find a demo of one here.
"Yamaha MU10 portable XG Midi synthesizer. These are great sleeper sound modules.
They play general midi as well as XG midi and sound fantastic.
Works via MIDI or serial using a macintosh style minidin.
The MU10 is on par with a MU50 in terms of polyphony/multitimbral. Just without controls or an lcd. (And you never really need those)
Tested, and clean. Works with AA batteries or any 12V power adapter (not included)"
