Howdy Mark,

It's all "internal". Ie, in Audacity, you can choose from a drop-down list of sources for recording, and to record Composer's MIDI output, I can either use "What you hear" or "Midi synth" and get a recording of the performance without having to mess with cables.

You can also record "live" audio through Composer (using the "record sound audition"), but in that particular case, you don't want to use "What you hear", because then the first track will also be recorded again (because you can hear it when you're recording the second track).

I tried it out using a drum track that I had. I played the drum track in Composer and recorded the performance in Audacity, using "midi synth" for the input. I then added a "fretless bass" track, and did the "audition" thing (double click the voice button to make it red), and then recorded my "freestyle" playing directly into Audacity, without playing anything in Composer. I have the settings in Audacity so that whatever has already been recorded plays as I record another track, so I could hear the drum track recording that I had already made. If there is any delay, you'll need to "time adjust" the tracks so they match up (this may be an issue for some synths).

You can also choose wave, microphone, analog mix (line, CD, aux), or CD digital as a source for recording. I haven't tried those out yet, though. Then when you're done, you can adjust panning, volume, as well as some effects (a goodish list, including EQ) and mix it down to a nice stereo file. I'm looking forward to working with it a bit more. It has a few strengths that my Creative Wave Studio doesn't have, and vice versa, so it is a nice tool to have.

ttfn,
Sherry
