Roland TR505 Rhythm composer from 1988. Used but in really nice clean condition, this has not been heavily used and is unmodified. Comes complete with original box which is in reasonable condition. Also the owners manual, preset rhythm score booklet, operation table guide, and MIDI implementation chart. Please note this does not come with a power supply or any cables.

Can be seen working in my Youtube video, all the buttons and functions work as expected. Only slight negatives are a small scratch to the left of the display, this can be seen in photo 3. It is not visible from every angle and is not in front of the actual readable part of the screen.

There is also some yellowing to the small buttons and the front edge of the unit, pretty typical of early grey electronic equipment.

Edit Update: Since listing I have tested MIDI with a MIDI to USB cable, connected to a PC running Midi-Ox. The incoming MIDI data is displayed in the window and percussion sound is output through the PC speakers.

Many thanks for looking!
