Pardon me if this is a really dumb question.  I have a laptop running Windows XP that is replacing an old desktop computer.  I will be installing some music recording/editing software (vendor not yet selected - but something very easy to use).  I plan to connect my drum machine and synthesizer module to the computer and control them with the software.  My old desktop had a game controller to MIDI port that was used to send MIDI information to these devices.  My laptop only has USB.  I was going to purchase a USB-to-MIDI adapter.  But it occurred to me, can I just use the XT Live to act as the USB-to-MIDI adapter?  That is, can I connect the laptop to the XT Live via USB and then chain the drum machine and synth to the XT Live via its MIDI ports?
