Coming from SONAR X1 LE is going to be a pretty massive upgrade. It would cost you $49 to go to the base version, SONAR X3. You'll get all the new core workflow features and technologies plus 12 instruments and 27 effects, 64-bit engine and unlimited tracks, send, FX, etc.. SONAR X3 Studio gives you even more for $149 with the ProChannel and 2 modules, the Blue Tubes and of course ARA integration and Melodyne Essential. I'm bias but it's definitely worth looking at the upgrade.
Music Creator 6 Touch is great too and perfect for beginners but for the $49, you will find SONAR X3 to be way more powerful. Just my opinion.
