My Echo Indigo works fine in my laptop for Giga OR sequencer with audio and VST instruments, but not together, it\'s only got one stereo out. I\'m considering the US-224 or the Maudio Audiophile USB, this is for live performance with 1-3 stereo audio tracks, a few VST instruments or one track of Giga, played live one at a time from a single midi in.

P4 Northwood, 5400 RPM drive, 512 RAM, SIS650 chipset, XP Pro.

Can I do this cleanly, no audio or midi glitches? Which will work better?
