The FrostWave is made by a company in Melbourne called, from memory, erm, FrostWave. Jonathan met the guy once. He operated, at that time, from above the Music Swop Shop in Elgin Street, Carlton (Melbourne, Australia for Merkins and other foreigners). Nice (but strange) guy. He seems to build them all himself. This thing has everything that opens and shuts, really. You could only do better by getting a Kenton Pro-4 or something similar. It does all kinds of voltage scales, DIN sync and even a weirdo joystick control thingy. Never tried the latter but performance artists might like it. Who knows?
