What is the latest Operating System firmware and where can I get it?
The last version released by Ensoniq is Version 3.50. When you power up the ESQ1, the first screen you will see displays the version number on the lower right on the display as shown. You can download the firmware from Rainer’s website and program the eproms yourself. If you don’t have the equipment, click here. Warning: Earlier versions (Ver 2.2 or less) will NOT load factory default patches to your internal memory when you reset your ESQ1 and you will loose any custom patches you may have created. Save your patches using the tape or midi interface.
