Many years ago I saw a company "GVP" listed in ALESIS (Pro Audio Company) trade magazine as being a licensee of their technology.
I have always wondered if this was the same amiga developer GVP and if they were planning to develop a pro Audio card based on ALESIS technology such as ADAT optic I/O and the Quadrsynth. A sound card based on this licensable technology would have completely blown away the soundblaster for its time...
