Paul - I don't have the Casio keyboard but I do use a Roland. so I can't be absolutely sure what cables are called for. Most keyboards I've seen have three MIDI cable connections in the back. The MIDI IN, OUT, and THRU ports on the keyboard are about 1/2" in diameter and have 5 pin connections. They look sorta like microphone connectors. I've never looked at the really low end Casio's but I doubt they are MIDI capable. Depending on exactly what you want to do will require one or two cables of sufficient length to reach your adapter and the your computer. You need one cable (MIDI-IN) if you only want to use the Casio only as an input to your computer and have the computer handle all the sound generation and playback. You need two cables MIDI-IN and MIDI-OUT if you want the keyboard's sound chip to handle some of the sound generation. I do this because the Roland chip for Grand piano is far far superior to the one included with Apple MIDI instruments. You need an adapter to connect the MIDI cable(s) to your computer. This can take several forms. I have a Serial to MIDI adapter by Opcode called the MIDI Translator II for one system and a USB to MIDI adapter by Mark of the Unicorn (see www.MOTU.com) for my Sawtooth. Both are small external boxes that have a single computer connection and several sockets for connecting MIDI cables. You'll need the simplest unless you plan to add a bunch of other MIDI inputs in the future. I believe that one can also purchase a PCI MIDI connection but I never investigated those. Then of course you need some kind of software to handle the data to be generated. I just read a review of Apple's Garage Band that sounds like it might do what you need. I happen to Finale because I mostly use my system for composing and creating written music. Tho it does handle MIDI input, sequencing, and playback, there are MUCH better apps out there to do that. I'm just not familiar with them. Good luck, John On Tuesday, February 3, 2004, at 12:13 AM, Paul Pippen wrote: > I have a 800mhz AGP and got a new casio keyboard to do some simple MIDI > recording.
