So before I went any further I bought all new screws for the front panel and spray-painted them black. In fact, four of them wouldn’t budge and had to be drilled out. I said before that the Delta looked brand new but I forgot to mention the screws. The sound is further divided into synth and string sections, the former of which is pushed through a variable filter (low or bandpass), the latter of which adds a nice ensemble effect to give it that string machine flavor.Īfter a quick clean of the sliders and outputs with a little DeOxit, I started to take the screws out of the front panel. A very nice square wave, it should be noted, but just that one waveform nonetheless. So yes, you can hold down all the keys at the same time but you’re limited to a square wave. It uses three divide-down oscillators to create all the notes (plus one more for high C). Before you get too excited though, it’s basically just a glorified organ. The Delta is fully polyphonic, no mean feat then or now. There was the Sigma and Lambda, both of which were largely preset machines, and then the Delta, which arguably offered the most control (until the Trident came out in 1980 and blew it out of the water).
#KORG POLY 800 BATTERY MOD CUTTING TRACES SERIES#
It came out as part of Korg’s series of three Greek letter-named polyphonic machines.
This time it’s a Korg Delta DL-50 Strings Synthesizer, a lovely machine from 1979. Ive worked on a Yamaha SK20 and a Roland RS-09 and RS-101.
