Sue,
The Yamaha PSR-350 is an older technology keyboard. It has two MIDI jacks on the back of it, so you'll need to get a MIDI interface. You may purchase an USB to MIDI cable interface that plugs into the USB adapter on your computer, and then into the two jacks on the keyboard. You have to make sure that the Interface is selected in Band In A Box's MIDI Options dialog as both the Input and the Output. You'll also need to make sure that the plugs are connected the right way, the MIDI Out from the Interface goes to the MIDI IN of the keyboard, and the MIDI Out from the Keyboard goes to the MIDI IN of the interface.

Any AUDIO recording you wish to do must go from the Audio output jacks to the Audio input jack of whatever computer you're using.

Is this YOUR keyboard, or the school's keyboard? If it's yours, you might consider upgrading to something a little newer, with a little better sound.

If you're a member of Costco, something like this would be a very good choice:

You can hear the Media Clips for this keyboard here:

You might also consider a replacement for the PSR-350 in something like the PSR-E413, for about $230.

The Media Clips are on that page, also.

Or, if you can really afford to drop some dollars, I'd recommend the PSR-S700 for about $1,000.
Listen to the difference in sounds!

All the newer keyboards I've shown you have a direct USB MIDI interface, where you load the driver disk, and away you go.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
