I recently began porting my project from VXAce to MV and after searching for an audio plugin in order to use multiple BGS files, I found your QAudio plugin but there's just a minor issue. While your plugin offers a number of features such as fadein/out and event emitters, one of RPG Maker's basic functions for "pitch" seems to either be missing/not added to your plugin or it doesn't seem to be an easily identifible command (eg = pitchX -> X is the BGM/BG/ME/SE's pitch value).
Maybe you can help out with this issue? I've already tried searching but I'm not having any luck with results.
Eg -> "qAudio start City_Streets bgs idBGS2 max50 fadein3 radius5 bindTo0 loop"
I wanted to set the BGS to a pitch of 75 (the scene this plays in happens at night, requiring a lowered tone).
