As you probably know , i own a Pa1x. After being a yamaha owner for about 6 years (psr8000) . I tried the tyros and did not feel it was sufficient an upgrade to change from my psr 8000 , then the T2 came along and it literally blew me away ! The individual voices sounded fantastic and i have said many times , there is nothing currently on the market as far as arrangers are concerned to compete with the Super articulation voices of tne T2. I was all set to buy the T2 when i heard the Pa1X. All i can say is that the Pa1x is weaker in the individual sound department compared to the T2 in almost every respect apart from the drum , bass and electric pianos. However when you hear the instrument as a whole it really is a quite remarkable instrument. Incredihbly flexible in terms of live and studio use and can be all things to all people. Which is why i bought it.
