Korg 770

Korg 770 Image

An ancient synthesizer from Korg. Aside from being very old, there isn't much else to say about the 770. It was released in 1976, is monophonic, very limited in design, flexibility and sonic possibility. It can make some weird noises largely due to its retro-cool ring modulator. You can also run external sounds through it. Bass, string and lead sounds are ok. It's got a fast envelope, auto bend, and LFO re-trigger too. An ole' classic that's fun to play with and useful if you're in the mood for buzzy analog sounds. It is used by Freddy Fresh, Simple Minds and The Human League.

I must agree with Chris, people who don't like this synth simply don't know how to get the best of it. The filter is a forerunner for the MS-20 filter and is wild and beautiful. There's a really cool Ring Modulator, the best I've heard apart from the Ring Mod on Yamaha CS series synths and there's some unusual pitch modulation possibilities to boot. The 770 also sports a High Pass and a Low Pass filter like the MS-20 and there's an external input, although I haven't tried this yet. With it's two oscillators, this synth can scream and it can whisper and it has a sound of it's own, somewhere between a Minikorg 700s and an MS-20. For it's size it packs a punch, and who can resist the cute front panel with envelope decay labelled as "Singing Level" (no kidding).

This synth makes a very strange, very distinctive bass sound that I have not found in any other synth. It's one of my favorites for that purpose. It's analog sounding yes, but kinda odd.
External input coupled with the "travelers" and ring modulator is fun to mess with. The white and scale noise generators are good for special effects.

Outstanding synth, people who don't like it simply doesn't know how to use it.
Both wild and smooth, he can do any sound, great for industrial.... and disco !
