TI as audio interface and Synth

[soulidstate]

Hi,

Ive got a plan of getting a TI desktop. I currently have a Tascam US122 as audio interface to PC. I do sequence on my Triton Extreme and my Classic's audio out goes to its(triton) audio input so my Triton acts like a 2 channel mixer.Triton's audio then goes to the US122.

Now,I know that the TI is an audio interface too. Can it serve as an Audio unit that can replace my US122 and function as synth module at the same time?My setup shall be Triton's audio goes into TI's inputs which goes straight to PC. Of course,when my triton plays a sequence,TI should play as a synth at the same time.

Would this be possible?

Thanks in advance.
Regards,
Em
