It's something that could be mentioned in the songs but that sounds more like a technical detail than trivia. I don't think it has much to do with character development so much as both mothy's improved tuning and software purchases and the tones he wants for the song.

Trivia I think would give it more in-story significance than it likely has. I feel it's more that mothy used the various appends to get the sound he wanted, not necessarily "X character is more aggressive/kind/etc so they are using X Append".
