Hi, I'm Japanese. I came across this video of yours by chance, and watched several other videos as well. Let me tell you one thing. Your music video are the best!👍
To be honest, I've used the HGSS overdriven guitar because it sounds much better on high notes than the B2W2 normal overdriven guitar and the B2W2 Kanto Champion overdriven guitar, because I needed a guitar for the background which sounds better in the low notes.
Yes, I try to work with the console's limitations and inject all of songs that are DS remixes. But I also use custom sound banks which means that not only the midi file is needed, but also the bank that I've created for the specific song.
I am sorry, but I still have a lot to learn too. There are so many things that I couldn't tell you. The best thing you can learn is by trying it yourself, like me! ^^
