I have both, T1 and S4…. and when I play out, I take my T1 for this main reason, the sound card is much stronger, louder and higher quality than the S4. I like my s4 for many reason and keep it as my home studio system. I have already had to send back my original purchased s4 for a new one under NI’s warranty, due to a faulty channel fader. Also the S4 has a tiny bug to it that if you’re not careful while going thru the motions of your mixing button pushing sliding etc. it will hiccup a mili-sec bump in the software making it obvious in the sound…. not good especially if your recording or playing live at all. The T1, no matter what button pushing sliding etc I do, never ever hiccups the mili-sec bump and contrary to your sense of touch by the “feeling” you get when touching the unit, I can tell you after over a year of owning, playing the heck out of it, taking it on road missions and club missions, I have not had one single problem to speak of about the unit; it’s been very durable and reliable. I always advice a person who is shopping for a controller, to play with one first, before you buy. I know that may be hard to do, being you might not know anyone with that particular unit, but I suggest finding a store such as the Guitar Center in Hollywood I go to, which has a variety of display units to actually demo on.
