New England Digital Synclavier 9600 Polyphonic Sampling System Brochure

via this eBay listing

"RARE! New England Digital Synclavier 9600 Polyphonic Sampling System Brochure

Yes, this is the 9600, and yes, this is in English.

This is THE RAREST and MOST SOUGHT AFTER of the 1989 new system brochures that that fake foreign website scanned the photos from 25+ years ago to show fake systems on the website (instead of real ones like Synclav com has shown for 20+ years). This is the original source of the scan, at least for the Synclavier 9600 model. Those photos show empty boxes. Uhm, what's holding that beige door closed (no locks)? And exactly what software generates that screen image?

This incredibly rare brochure gives all the information, and shows all the specs of the Synclavier 9600. And surprise! The maximum polyphonic sampling memory is not "1.5GB", lulz.

And, lastly, Synhouse has the Synclavier 9600 in stock (two kinds, actually). Nobody else does."



New England Digital Synclavier Brochure VPK Sample-to-Disk VT640

via this eBay listing

"This is an incredibly rare brochure from the summer of 1984 (when NED was working on polyphonic sampling Synclavier to be shown October 1984 and there was no actual system in production, the few shipped were hybrids of the Synclavier V/PK retrofitted to a Synclavier II Control Unit) that shows things that NED didn't exactly make, ever.

This was their first---and last---mention of "The Tapeless Studio" meaning the sequencer (later that meant the Direct-to-Disk system). It describes the SMPTE Reader Option without using that term because it wasn't yet available and they hadn't figured out how it would be done yet (similar to the 1987 discussion of the not-yet-released 3rd party SMPTE reader for the Linn 9000, saying they weren't sure whether or not it would require additional hardware to be added to the Linn 9000....that's the sound of someone who hasn't ever used SMPTE and doesn't know what it is), and it shows a graphical flow chart showing polyphonic sampling and multi-channel outputs (neither available then as building blocks), and is intentionally vague about the "floppy disk system" and "Winchester disks", as they didn't really have the set offering for that (high density Superfloppy, not out until 1985, and 5mb and 10mb IMI MFM Winchester drives being common, neither with SCSI until 9/1985).

It describes the Stereo Option, Sample-to-Disk, SCRIPT/MAX, and different Control Unit enclosures.

Most strangely, it shows a V/PK that never existed, with a back panel that wasn't made, with Synclavier II connectors that were never used and, sadly, an on/off power switch that they never put on this $11,000 machine.

The Sound of Prince with the Oberheim 🎹

"(c)2007-25 by RetroSound
supported by UVI: http://bit.ly/retrosound-uvi

One of my favorite tracks from the 80s.
When Doves Cry by Prince from the album Purple Rain (1984)

I used the 1010music bento with LM-1 samples and tuned the sound.
The bento works great as sample based drummachine for me.


And I used the Oberheim OB-Xa synthesizer for all synth sounds.
I played the guitar sample with the E-MU Emulator II."

NightRadio - Where (2008) demo


video upload by Alexander Zolotov

"This demo was created in 2007-2008 using an early version of Pixilang 1.x. The music was written specifically for this work. But something went wrong, and the demo ended up gathering dust in the archives until 2025, when I decided to restore it, make minimal edits, and finally release it in video format. The source files will be made public later. By the way, the 'Where' soundtrack, unlike the demo, was not abandoned and was released as part of the 'Back to the Sources' album in 2009. The music, of course, was composed in SunVox."
