Passort Designs Soundchaser and Mountain Computer MusicSystem
The Passport Designs Soundchaser Computer Music System is a package that includes a Mountain Computer music synthesizer and the Soundchaser piano-style keyboard for music input. The system hardware and software allows four-track recording and sound manipulation, using the Apple II as a controller. The keyboard case is 29" long and is made of solid wood. The keys are full-sized. A ribbon cable connects the keyboard to its interface board, which goes in slot 7.
Dave Pratt - the designer of the ComputerEyes digitizer boards - purchased this particular system new in the early 1980s and used it for his home computer music hobby. It cost over $1,200 new.
The music synthesizer is a set of two circuit boards (using slots 4 and 5). It's a sixteen oscillator (voice) digital synthesizer, with software to control it. A light pen is included that interacts with the software to manipulate music on the computer screen. A stereo output is provided.
