I am just getting started in music and MIDI. I have a Trinity rack mount and Cubase VST.

First, can I use the Trinity to function as a soundcard?

Second, I want to use Giga, Cubsase, and my Trinity. If I do need a soundcard, what is the cheapest one that will work with both with a MIDI in/out/thru?

What are some other options to get MIDI in if I don\'t have it on the soundcard?

Finally, Does the quality of sounds sampled on Giga depend on the soundcard?

Sorry for the elemtary (and some off topic) questions, and thanks for the help.
