Background and Legacy

The original Ensoniq ESQ-1, released in 1986, combined digital oscillators with analog filters and included a built-in multitrack MIDI sequencer. It was distinguished by an affordable price and a unique gritty, lo-fi sound from its custom Ensoniq 5503 Digital Oscillator Chip. The instrument became popular among musicians and was a foundational product in the development of music workstations. Cherry Audio's plugin celebrates the ESQ-1's 40th anniversary by offering a modern yet authentic recreation.

Intended Users

The ESQ-1 plugin is aimed at musicians, producers, and synthesizer enthusiasts who seek the classic sounds and workflow of the original ESQ-1, enhanced by modern performance features and integration capabilities in today’s digital audio workstations.
