automatic pitch control
with my synthesizer in soundcard signal input i play while listening winamp music. unfortunately not all songs are "tuned" as my keyboard (440 hz. so with some plugins i can adjust the music pitch to my keyboard. but it always takes some time and the next song might have an other "tune".
who knows some pitch-control plugin with memoryplaces to save adjustments of each song?
who knows some pitch-control changing the pitch automatically by analizing a song like a guitartuner up/down to 440 hz
