Opcode Systems

Opcode Systems, Inc. was founded in 1985 by Dave Oppenheim and based in and around Palo Alto, California, USA.

The products were announced at the New Orleans Summer NAMM (June 22–25) (after which Apple objected to the name)[4] and, according to composer Laurie Spiegel, publicly available in July, 1985.

In 1986, music software programmer David Zicarelli licensed his Editor/Librarian for the Yamaha DX-7 to Opcode, which published this product.

[6] EZ Vision's successor, MusicShop, included a simple notation view - a first in a sequencing product in that price range (roughly $100 US).

Also in 1989, it licensed the computer music authoring system Max from IRCAM, where it had been developed academically by Miller Puckette.

Studio Vision was the first-ever commercially available product integrating MIDI sequencing and digital audio editing and recording on a personal computer.
