Brand: Excel Sound Corporation
The Excel Sound Corporation ES-70 ES 4 is a synthesizer model produced by the company during the 1980s. ES stands for Electric Symphony, which was a trademarked techno-pop-inspired sound that Excel Sound pioneered in the late '70s and '80s. The ES-70 ES 4 featured four oscillators per voice (hence the "ES 4" in the name), each with selectable waveforms like sawtooth, square, and pulse. It also included digital effects like chorus, phaser, and flanger, as well as a built-in drum machine and sequencer. The ES-70 ES 4 was a popular instrument in the synthesizer market of the time, known for its bright, punchy sound and distinctive electronic character.
