This is the web home of Real World Interfaces - Tina's and my business which primarily concerns hardware and software for electronic musical instruments.  Real World Interfaces was established as a business name in 1985, although my involvement in musical instrument modifications began in late 1980 with mods for the Casio M10 portable polyphonic digital keyboard.

I used to do modifications for the Roland MT-32.  Please let me know if you are interested in this.

The main products and services are described in the following directories:
