Welcome to the forum, both of you.
williamj57 (are we cousins?
), to record the
sounds of your keyboard, you'll need to connect audio cables from it to the line inputs of your audio interface or sound card. Set the patch on the keyboard, mute all other MIDI tracks, arm an audio track, press play and set your recording level, stop and rewind, then click record in MC 7.
To get MC to play all of your keyboard's sounds, you'll need that keyboard's Instrument Definition. That will show a selectable list in the Bank and Patch boxes of MC and will play your selected sounds from the keyboard. You may be able to find the ID on the internet if it's a popular 'board, or you can create your own.
Each MIDI track should be on a different channel, otherwise they will play the same sound no matter what patch you select when played through the same synthesizer.
MIDI is not sound, it is just data that tells a synthesizer (hardware or software) what note to play, when to play it, how loud and long the note sounds, and when to stop making the sound. Recording the MIDI output of your keyboard will not record the sound of your keyboard.
If your keyboard can play General MIDI (GM) patches, select that in the track's MIDI properties.
Or try out some of the software synths that come with MC 7.
