Description | 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. |

| Velocity |
As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. |
Aftertouch |
Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel. |
| Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise. |
