🎹 Ensoniq SQR Rackmount Synthesizer

Ensoniq SQR rackmount synthesizer in good condition. This is the original SQR, not the SQR Plus.

🔋 New Battery

When I received the unit, it displayed a “Battery Low” warning. I installed a new battery with a battery holder, and the warning is no longer displayed. The battery holder makes future battery replacement much easier.

🎛️ Testing & Condition

• ✅ Checked all front-panel buttons and controls
• ✅ Checked the display and menu functions
• ✅ Checked the available parameters/edit functions
• ✅ New battery installed
• ✅ Battery Low warning is no longer displayed
• ✅ No issues found during testing
• ✅ Complete

I do not currently have a MIDI setup, so I was unable to test note triggering, MIDI operation, or audio output from the synth. All testing that could be performed without MIDI was completed, and everything checked appeared to work properly.
