Hard reset for the Ensoniq ESQ-1

How to perform a hard reset on an Ensoniq ESQ-1

In this guide, we will show you how to perform a hard reset on an Ensoniq ESQ-1 synthesizer. Follow the steps below to get started.

Note: When re-initializing the Ensoniq with O.S. version 2.2 and lower, all internal programs will reset to BRASS 1. Higher versions will load the forty factory sounds.

  1. Press and hold the RECORD button.
  2. Press the Soft button (1) on the upper left-hand corner of the screen and then release both buttons on the Ensoniq.
  3. The display on your Ensoniq will read ERASE ALL MEMORY AND RE-INITIALIZE
  4. Select YES. The Ensoniq display will return to the sign-on message. All RAM is erased, and all internal programs are reset
  5. Press and hold the RECORD button.
  6. Press the FILTER button, then release both buttons on the Ensoniq. 
    • Verify that all filter values are between 140 and 160 inclusive. If they are not within these values you should probably have your Ensoniq ESQ-1 serviced at an authorized service center.
