These are cool. They have aftertouch and can run on batteries. They are based on a popular 4 operator Yamaha FM synthesizer chip (same as FB-01) and are setup much like any other KORG synth otherwise. There are combinations that you can program to send external MIDI if i'm not mistaken. They are pretty cool for an FM-synth.

You can find them between $100-$200.

I used to have a blue one!

I have a 707.
It's really cool for live gigs.

It's the same soundchip as found in the Yamaha DX-7, but with an analog subtractive like interface with filters and envelopes.

It can also be used as an multitimbral synth for up to 8 midi inputs.


The sound are rather thin, but great for bells, bass and pads.

The korg DS-8 is the same synth except for the FX section which the 707 doesn't have.

The 707 can also be used as a cool mother-MIDI keyboard.

It has been used by Juan Atkins

From what I understand, the DX-7 uses a 6 operator chip, whereas the 707 uses the cheaper 4 operator version of the same chip with louder modulators to help compensate for the 2 missing operators.

The 707 and DS-8 both used the 4-operator YM2164 (OPP) chip.
