Hi!
You asked about how to use a music interface with accessible
software. I strongly recommend that you take a look at :
http://www.DancingDots.com
They have products that can help you do what you want with your
music. As for not having a USB port for your keyboard, you would
need a midi cable to connect it to a port that is something like what
your monitor is attached to but that is for a sound card. And you
might want to get a higher-end sound card too.
Hope this helps,
Sharon
