Was trying out a search on Bing.com (Microsoft's new search engine) and this popped up. It was an experimental instrument from 1987, and that's sorta how it sounds Here's a brief excerpt from the Buchla site:

Based on sealed membrane technology, the 700's input structure provides a comprehensive interactive editing and mode selection facility. Position-sensitive transducers are used to implement conceptual potentiometers, flywheels, switches, ribbon controllers, and other gesture-sensitive paraphernalia. Light emitting diodes display the status of touch sensitive keys, and a super-twisted liquid crystal display indicates the functions and settings of touch sensitive controls. Three MIDI ports comprise the 700's primary performance inputs. Under software control, MIDI channels from any port(s) can be assigned to any of the 700's voices, thus enabling simultaneous control from multiple MIDI devices (which might include keyboards, guitar controllers, drum machines, pitch followers, space wands or personal computers). Other inputs accept control voltages, pulses, foot pedals, and SMPTE time code. Two RS232 ports provide for communication with computers, modems, terminals, and printers. Control voltage and pulse outputs, three MIDI outputs, and special control signal outputs complete the 700's comprehensive I/O facility. More information on the B700
