Plug the audio outputs of the Trinity into the aux. inputs (or line inputs) of the sound card. Use any common sound recording program to record the Trinity at 44.1 kHz, stereo. You can then use this file to burn your CD-R.
If you have the HDR-TRI (hard disk recording) option, you could bypass the digital-analog-digital conversions and record directly into a sound card that has a digital audio input (such as the SoundBlaster Live).
If you have the DI-TRI (digital interface) option, you could record directly from the Trinity, through a fiber-optic cable, and onto a sound card with a ADAT optical input, such as the Korg 1212 I/O sound card, or the Midiman Lagoon card.
