My brother and I were just reminiscing about some of the very strange toys we had in the 80s. One which we both remember was this cross between a guitar and a xylophone. It was electronic, and about 3 feet long, white. It had maybe 36 colored “keys” on it (they weren’t really buttons, as they didn’t press down very hard, so that you could run your hand up or down for a long scale). It came with a book of music that you could play on your own.
It wasn’t a keytar, as they keys weren’t in any piano-like configuration. They were about the size of Guitar Hero buttons, but much closer together. Any ideas?
