This is my reliable Roland JV-1010 that I used with an M-Audio midi keyboard. I’m the original owner and it includes the original Roland power supply and ships in the original box. There are just a few minor scratches, but otherwise, it looks good and functions perfectly. This synth module can be expanded with additional sounds (I previously used an Orchestral II expansion card with this module which I’m selling separately.)

The Roland JV-1010 (released in 1999) is a compact, half-rack sound module that packs the acclaimed sound engine of Roland's flagship JV-1080 and JV-2080 synthesizers into a portable footprint. It features 64-voice polyphony and comes with over 1,000 professional sounds right out of the box.
