Logic won't pick up my keyboard..
I need help.. ok so first off I am using a macbook pro to run logic 9 in and recently just updated my system to mountain lion. I am using (or trying to use) a tascam US-600 interface that connects to my computer via USB the interface connects to my Yamaha keyboard via MIDI cable. Now, before I updated to mountain lion the keyboard worked perfectly. I could plug it in and unplug and plug back in with no problem. The problem is that when either the computer goes to sleep, the USB that is connected to my computer is unplugged, or the piano is turned off logic can't pick it up again unless I restart the computer. I downloaded the most recent driver for my tascam i think.. but I don't know of anything else to do and restarting my computer to use the keyboard is a pain in the neck... any advise or suggestions are much appreciated.. thanks.
Logic Pro, OS X Mountain Lion (10.8.2)
