So, i want to buy the software but I was wondering if I needed to buy melody assistant/harmonic assistant to work with it. I have the free version of harmonic assistant downloaded and it would be nice to know for sure before I went out and bought even more software.
Definitely, Virtual Singer needs Harmony/Melody Assistant. It is sort of built-in. As for trying out, you only need to download and install either (or both if you want to compare them) HA or MA. You can use VS even in demo mode : I think it will run a few times only in each session, that's the demo limit.
