Korg Delta

YouTube via thegarranimal
"This is a quick demo of the Korg Delta from the late 70's featuring BOTH a synthesizer section and a string ensemble section. Just showing the functions are in working order, no noisy pots or sliders, and the kinds of interesting old analog sounds this machine can make."

Korg DW-8000 quick sound demo

YouTube via thegarranimal
"This is the Korg DW-8000 analog/digital hybrid synthesizer up for sale on Ebay. Just a quick demo showing the kinds of sounds it can make. It can sound like a Memorymoog, Juno-106, Oberheim....all kinds of things. It can also make all sorts of weird digital sounds but I didn't create any patches of those."

J. S. Bach on synth - Gavotte from Orchestral Suite no. 4 in D

YouTube via syntesen
"Yet another "switched-on bach" project in the style of Wendy Carlos. This time, a wonderful dance from the fourth Orchestral Suite, the Gavotte.

In 4/4 time, but with the emphasis on the 3rd beat of the measure, rather than the 1st, the Gavotte was a royal court favourite in the francophile countries of the Baroque period.

This piece marks the beginning of my "Soft Synth Odyssey", realizing different tracks with different software synthesizers. To start out on familiar ground, this track was realized with the Arturia Moog Modular V2 emulation synthesizer, recorded in Ableton Live.

I hope you enjoy it.
