sooo I may have mostly restructured ADSR since my last devlog, so now you can change the settings in the middle of a note being played. now there is a single function that takes in the time since the note was played or released and returns a volume based on the current ADSR settings, instead of the note storing the settings upon being pressed. I also found out concurrent hash maps are a thing, which will hopefully fix some of the issues I was expecting to have implementing live key pressing.
