envelope fading in at the current time

add vidref on mousemove. separate process? yes, vidref polls CC when

music is paused

sub autocomplete

fix fader UIs

be able to select grid lines to delete them. maybe grid is on a

special curve row

hotter reloading of subs and values. from KC, drag a new sub into CC
