changeng brought us the debut this weekend of this device. It’s a lot of things. A split keyboard. A dual-neck flying-V keytar. A “Sound Mixer”. A light show. $9.95 at “Big Lots!”. A really big mistake. An aleatory composition device that produces unpredictable sound patterns RIGHT OUT OF THE BOX! Ladies and gentlemen, the device Stuart affectionately calls “THE HUMP”: THE HMP-288!
