Hamilton PCB had a hand in the early development of electronic music. In the 1980's Keith Hamilton worked with

Hal Chamberlin and David Cox of MTU (based in Raleigh NC) to help develop an early digital / Analog converter, the Digisound 16.

that was used to generate music.

Later Hal Chamberlin moved to Kurzweil Music, he is now head of R&D for Kurzweil.

Hamilton PCB designed the printed circuit boards for the K2000 , PC88 series of electronic keyboards,

and many other Kurzweil products.  In the early days of electronic keyboard development Hal Chamberlin cooperated with

Bob Moog, famous for his early Moog synthesizer keyboard.

The K2000 was the Kurzweil flagship product for many years. It took 10 years for competitors to match the performance of this product.

Later the PC88 was designed, it also was a midi controller.
