The MIDI Companion (formerly Kurzweil Companion) is your remote interface to the best keyboards in existence, the Kurzweil K2500/K2600/K2661. This is the Mac OS X version, there will be no further updates to the Mac OS 9 version. The Companion allows you to control your Kurzweil from your Mac. This saves wear and tear on the Kurzweil buttons and it allows you to work more efficiently. Take the simplest task on your Kurzweil. You've just created a new program, or layed down the first track in a sequence. The Kurzweil wants a name for this new object, and you sit there for 5 minutes spinning the data wheel or pecking at the keypad to enter "Rad Piano" or "Techno Song". Forget it! Now just reach over to your Mac keyboard and type on a normal keyboard! And that's just the start. The Companion allows you to see your Kurzweil screen remotely, allows you to enter numeric data for things like frequencies, select programs from a complete, searchable list instead of 8 crowded lines, export the list of objects in your machine, and more... By the way, I need some feedback on your use of the Companion.
Mac OS X 10.3 or later (It may work on prior versions, we have not tested that), and a two-way MIDI connection between your Mac and your Kurzweil.
