Hey Scott and Jose - Glad to be among the T4 crowd! I studied it for quite a while before taking the plunge. There are so many videos out there and once you get past the frills of the vocal sounds (which are indeed amazing too), there is so much more to be excited about. I know how things sounded on the T2...and all I can say is they sound "MO MO Betta" on the T4. Took a bit of a loss on my T2 but I am elated that I made the upgrade. To date, I have not had the time I would have liked to thoroughly familiarize myself w/all the new features, but that's mostly because every time I turn it on and start playing it... time flies and it's midnight! The board is a wonderful instrument for sure. I have really not regretted a single dime I've invested in all the keyboards and upgrades I've made along the way. Heh heh - But that's cause my brother collects motorcycles...so, hey, I feel great! Oh, and I don't need no helmet to play the thing! HA HA! But seriously, the T4 has inspired me to play more and more keyboard - something that I also enjoy tremendously. It was a great purchase! Thanks Frank!
