Official AIM Review!
Wow, super creative. There are a couple instances where the mix gets a little muddy, and at points the lyrics sound like word salad to a native English speaker -- but this is relatively common with vocaloid.
I would recommend perhaps dialing down the distortion just a bit on your guitars/bass -- maybe bring them and Gumi down a few dB so your drums can stand out a bit more.
For guitar and amp sims, I'm familiar with Shreddage and GuitarRig but prefer the more natural sound of RealEight (and its lovely keyswitches) and the ease of use of Grind Machine. It seems like you know the ins and outs of your programs fairly well, but distortion on your guitars was muddy, and tone was unclear, hence the recommendation.
Intonation on Shreddage sounds like it needs a lot more velocity applied. Some notes sound a bit machine gunny or intonation too surgical.
Drums sound solid, though they're hiding in the mix under those guitars.
Now, onto writing -- I'm blown away by how surreal these lyrics are and how well you've used Gumi to convey them. Melody is catchy as hell, and those portamentos will be stuck with me a while. I've gotta invest in installing her one of these days.
Great work. Thanks for turning out to this year's competition!
