Be sure to add me to your favorites list Original Roland Educational / Music Book and Disk, "Melody Games", for Use with the Roland PR-100 Digital Sequencer. This is a good condition original supplemental manual book for the Roland PR-100 Digital Sequencer Disk Drive unit. This is an educational book on using the PR100, but also a music book as well. One PR-100 Quick Disk comes with it, but I have no idea if the disk works or not, as I have no working PR100 myself. There are marks creasing and wear on the covers and some of the pages. This book was made by Xanadu publishing for Roland and it's a great resource if you have one of these now vintage midi digital sequencers. Genuine original book from the late 80's, with the disk included, but as I wrote before the disk is untested and I do not know if it will work, so this is sold as it is. This is a manual or document, this is NOT a piece of equipment or instrument. If you have any questions, I'm always happy to answer them. Thank you so much for looking! Please check out my Store!
