Okay guys, here is my first post, so cheers! :] Now here is my problem broken down into a nutshell. I've had logic 8 for some time now and i run it on my macbook pro. It has worked wonderfully for the past several months and i have fallen in love with this program. But now i've run across a problem. I've always used midi and i've used my Casio CTK-720 as a midi controller. Like i said, i've had no problems with it for the past several months. But recently, all midi input stopped working. Logic doesn't receive any midi data from my keyboard, and whatever i play on my keyboard does not play through my monitors either. I can play the songs and midi data and hear them just fine, yet like i said, i can't hear my keyboard play through the speakers at the same time, and it shows that no midi signal is being processed or received in Logic either. I have several files, and this has happened to every single one of them, which is telling me that it's not only a bug with one single file. But more so a software and global control issue. Now, it could possibly be due to a bad USB cord, but i'm not sure. When i plug the usb from my keyboard into my mac, it doesn't show a loading screen for the keyboard like it used to. So it may be that, but i haven't had time to run to the store and pick up another cord yet today. So i'm posting this in hopes of some responses before i get the chance to run to the store later. All help is much, much appreciated!
