Korg 770 - demo and test

Note: Auction links are affiliate links for which the site may be compensated.
Published on Oct 19, 2016 Keith Negley

"This video is just to demonstrate the functions and working order of my Korg 770 analog synthesizer up for sale."

via this auction

"Korg 770 mono-synth in very good condition. Serial#: 770486
It is 100% functional. Every knob, slider and key works flawlessly with no scratchy pots or sticky keys/sliders. Previous owner had it serviced inside and out (5 years ago?) and had cv inputs installed in back. I've never used the cv inputs so I can't speak to how they work, but the owner demonstrated it to me when I bought it and they were functioning just fine. It has a few minor scuffs but nothing major and nothing that inhibits it's functionality. Note: It's missing the silver ring to the portamento knob (see pictures). The video link is my actual synth to demonstrate it all works great for this sale."

PATCH.DIARY.2016.10.19 from Phosfiend Systems on Vimeo.

"First composition with my new case, so much room! Not a lot of hands-on work here, except for some subtle sound tweaks, mostly driven by the DAW.

Main synthis the left ShapeShifter with voices 1,2 & Pulse outs being mixed hotly and fed into stereo (L&R) LPFs on the Korgasmatron.

Percussion is:

Kick via the Blue Lantern Asteroid BD V4

Clang via the Basimilus Iteritas

Snappy filter crackle thing via the seconf Shapesifter, being fed through the band pass of Ripples, with some semi-lost pitch data

A punch of Peaks voices with hihats and deep fm snaps"
