quality of recording audio from ti usb

[00264167]

im using the ti as a soundcard with the usb as my pc soundcard is a cheap one.
is there any problem with the quality of the audio using the usb connection when youre recording a set of midi tracks to audio?

i read in the tutorial that its best to switch to the analog outs when recording audio:

"While recording, we recommend that you switch the Main
Outs of the part you are about to record to Analog 1+2 instead
of USB. This way, the audio data doesn’t need to travel from
the Virus TI into the Virus Control and from there to your audio
interface. Instead it’s being sent straight to the Virus’ analog out.
Once you have finished recording this particular track, switch
the Main Outs back to USB in order to allow this part to be fully
latency-compensated."

i assumed this would be to do with reducing latency or something but could it also be theres a limit to the amount of audio that can go through the usb and affect the final audio quality. ive always used the usb connection for recording up til now.
