When you consider how much music technology has changed just in the last 10 years, it's mind blowing...
Celemony has developed unbelievable pitch correction software since 2001, but now they're releasing what they're calling "Direct Note Access". This is a feature that they will include in all the latest versions of their "Melodyne" software.
Basically we can now edit individual notes within chords and polyphonic recordings! What was once only possible with MIDI is now a reality with real audio. Amazing.
