I have toyed with Hookpad a bit, and it's really good. Even without Aria Ai, there are tools to sculpt songs. I'm this close to getting it. You can't see it, but my thumb and first finger are really close together. They keep adding new stuff that makes it appealing. $200 is a little steep for me right now though.

I think with Hookpad, it might work better straight into a DAW with SynthV. It's similar to Scaler, but more intuitive.
