I went to Sweetwater and grabbed the Dream Machine package for $29 along with two MIDI packs for $10 each (Drama and Hooks & Chords).

I downloaded and installed the whole thing and I can see this is going to be quite a lot of fun! As much as I like the keys that came with I look forward to a sale on a piano so I can use this with basic piano sounds though.

Thanks to Dan for starting this thread and turning me on to EZKeys as well as answering my questions.

Thanks to Floyd for patiently answering my questions in perfect detail.

Thanks to Pipeline for always helping with tech tips to get the most out of these tools.

Thanks to Mario for being a resident MIDI supporter and expert for those of us who know nothing about it.
