Opcode, power house Mac MIDI sequencing and audio recording software and MIDI interface hardware for the Mac (although they did make some apps for Windows). They were purchased and totally destroyed by the very special assholes at Gibson Guitars.
Not only did Opcode produce excellent MIDI software for the Macintosh but they also made the some of the best MIDI interfaces for the Mac to ever exist. It all started with the Opcode MIDIMAC back in 1986 and went on from there. Read more about Opcode Studio Series Macintosh Serial MIDI Interfaces
All the Opcode Studio manuals listed below are in PDF format. I am still searching for a PDF version of the Opcode Studio 3 user manual. If you have access to this file, please contact me.
Opcode's greatest contribution to the MIDI world was probably the Opcode MIDI System, a.k.a OMS (which was later renamed the Open Music System). OMS was a set of system software for the classic MacOS that managed MIDI routing and processing. Read more about The Opcode MIDI System a.k.a OMS
Opcode made MIDI and later audio software for the Macintosh platform in the late 80's and the 90's. Eventually they did release their MIDI sequencing app Vision for Windows as well, but their primary focus was always the Mac. Read more about Opcode Software and Hardware
Opcode released their flagship MIDI sequencing software Vision back in 1989 for the Macintosh. Vision was very well received and was on the top of it's game at the time, winning several awards. It was in 1990 however that Opcode gave birth to Opcode Studio Vision.
I have a lots of fond memories of hours upon hours spent in Studio Vision. Studio Vision stood out as the first MIDI sequencer to integrate digital audio recording. It was the first sequencer that i ever owned (software or hardware) and served me well starting back in 1991 on my old Mac IIci. Read more about Opcode Studio Vision MIDI Sequencer for MacOS Classic
