PROBLEM: Review: I had this charger for over two years. Last week while it was plugged into my computer, it just died. No blue light no current. I ended up splicing the connector to my old frayed Apple charger. The connector is much better than Apple's. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: This book really should be removed from circulation. While basic MIDI information is in there, it is so out of date it just makes it hard to read. Examples are of obsolete or vintage gear and has no real relation to todays musician.Illustrations are all cheesy and look like bad microsoft clipart. Photographs are all poor and dated. The section on MIDI and a personal computers lists atari and commodore as possible good choices - get the picture!If you are looking for charts of Control codes etc, - they are in here, but you can find those anywhere. If you are trying to get information on MIDI in the last decade or so, buy a different book.
