Synopsis:

First digital (6 operator, 32 algorithm FM) synthesizer to unseat the analog synths as king Architecture Class: FM.

Ebay Description:

The Yamaha DX7 is a 61 key pressure and velocity sensitive (16 voice) FM synthesizer, featuring 6 operators (32 algorithms) with dedicated (4 stage) envelopes, a (4 stage) pitch envelope, an LFO (saw:up|down sine square triangle random waveforms), 32 editable presets, cartridge interface, breath-control and pedal input, and MIDI.
