Hi,

To patch into the soundboard means to run a cable from the outputs (aux. or headphones....Mackie mixer headphone signals are as clear as any other output on the board) to the input on the minidisc. Then to record it into the computer you run a cable from the headphone out jack of the mini-disc to the soundcard in your computer. Your computer likely has some sort of small WAV editor or some such or something like MusicMatch Jukebox which lets you convert files to MP3's or WAVS. If you want really good sound then stay away from MP3's as they are compressed files with much lower audio than CD quality. Hope this helps.
