by Miller Puckette. Opcode began selling a commercial version of the program in 1990, developed and extended by David Zicarelli. Never a perfect fit for Opcode Systems, active development on the software ceased in the mid-90s. The current commercial version of Max has since been maintained and distributed by Zicarelli's company, Cycling '74 (founded in 1997), since 1999. In 1990, Opcode introduced Studio Vision (initially called 'Audio Vision'), which added digital audio recording (using Digidesign's digital audio hardware) to Vision's recording and editing platform. Studio Vision was the first-ever commercially available product integrating MIDI sequencing and digital audio editing and recording on a personal computer. Paul J. de Benedictis was the Studio Vision product manager and helped come up with the idea of audio and MIDI in the same product after speaking with Mark Jeffery, a Digidesign employee key to their software development. A version called VisionDSP was released just before the company folded. Caitlin Johnson Bini, Senior Tech Writer, wrote the Studio Vision, Vision, EZ Vision, and Galaxy user manuals. Opcode's hardware products included a line of serial MIDI interfaces which included the Studio 3, Studio 4, Studio 5, Studio 64X and 128X, as well as USB interfaces including the DATport, SONICport, MIDIport and STUDIOport lines. In 1998, Opcode was bought by Gibson Guitar Corporation. Development on Opcode products ceased in 1999.
