Opcode Systems, Inc. was founded in 1985 by Dave Oppenheim and based in and around Palo Alto, California, USA. Opcode produced MIDI sequencing software for the classic Mac OS and Microsoft Windows, which would later include digital audio capabilities, as well as audio and MIDI hardware interfaces. Opcode's MIDIMAC sequencer, launched in 1986, was the first commercially available MIDI sequencer for the Macintosh computer and one of the first commercially available music sequencers on any commercial computer platform.
