I had this listed before but the floppy drive was being intermittent. I've installed a Gotek USB Emulator, with HxC firmware, OLED display, and rotary encoder, and it's booting reliably now. I also recapped the power supply. I'll include my USB stick with bootable floppy disk images.

The Ensoniq ASR-10 is a legendary 16-bit sampler/workstation celebrated for its warm, musical sound, powerful effects engine, and deeply expressive sampling workflow that defined countless 90s productions. With its iconic purple screen, real-time performance controls, and unmatched creative flexibility, it remains a studio classic for producers seeking hands-on sampling with character and depth.

This keyboard is in good condition.  Has 16MB of memory installed.  Boots and passes keyboard tuning, loads samples and effects from the floppy disk, and plays from the keyboard (all keys are working).  A few screws are missing. 

Because of the weight of the keyboard I am selling this as local pickup only.  Prospective buyers will have a chance to try out the synthesizer and confirm they are satisfied with it before they carry it off.  Once it has left my possession, all sales are final.
