A good entry level digital synth. It's small in size, simple in its design and offers fairly easy editing. It is a digital FM type synthesizer which makes some very thin and digital but sometimes interesting sounds. The synth engine is similar to the DS-8 without on-board effects. It isn't necessarily useful for any professional work but if you want a lo-fi cheesy digital sound from a toy-like synthesizer then give the 707 a try! It can even be strapped on like a guitar. It is used by Juan Atkins.
