About the Item

Up for sale is the iconic Yamaha RM1x hardware sequencer and groovebox.

The unit is in full working order, thoroughly tested, and ready to go—no hidden defects. All buttons, encoders, potentiometers, ports, and the floppy disk drive function properly.

The factory LCD display is sharp, clear, and high-contrast, with no dead pixels or missing lines. The button/indicator LEDs have been modded: the stock LEDs were replaced with fresh white LEDs, giving the unit a clean, modern look when working in dim studio setups or live on stage.

Cosmetically, the casing is in good condition—it shows typical minor scratches and light signs of use, but overall it is very well preserved considering its age.
