Midi Newbie Using Pro Tools Free, Midi is a good thing, right? Options

[cydonia]

Hello.

Well i've been using pro tools free for audio recording, G4 450 448 MB Ram, OS 9.2. Kind of getting the hang of it.

I'm using a my old 4 track cassette recorder, apparently for its "pre-amp" capabilities. I also have an imic.

Most of the music i do is synth, techno, with some vocals.

I've been recording audio using my synth, but i recently bought a midiman midisport 2X2. I want to use midi, i've figured out how to record a track, but i can only play the sound through my keyboard. If i create an auxillary track, i can hear it through my computer speakers, but once i'm done recording and turn off the keyboard, i can't get any sound from the computer. I know there's a difference between midi files and audio, but i'm having a really hard time getting my head around this stuff. I'm reading the manuals, it just isn't clicking. It's too technical.

I'm used to plugging my synth into the 4-track, hitting record and that's it. Is this possible with midi? Can you offer some advice?

Thanx!
