I am having a similar problem. I am using PT11. My computer has the following system properties. Microsoft windows XP Home Edition Version 2002 Pack 2 with AMD Sempron(tm) Processor 3000+ 1.81GHz and 384 MB of RAM. I am trying to record from my Yamaha PSR-290 via MIDI leads in to the computer and it's not recording anything on MIDI, just keeps saying Audio has been recorded and do I want to save it. In MIDI Devices (within Option) the only Input Driver I have in the window is USB Audio Device. I have the same available in the Output Driver window along with several others. I have tried changing some of th Output Drivers but to no avail. It's getting really frustrating. In the PT manual on page 8 Step One - MIDI Setup, it shows a picture of the Input Driver window which has 2 drivers in it:
In USB MidiSport 1x1 and SB Live! MIDI Port [B800] I can't get either of these. Please can someone help me to record my own MIDI Music.
