Another little clue that the world of polyphonic note recognition is with us (and ever improving) I received this e-mail today
Dear Adrian,
The first ever Polyphonic Guitar Tuner is now in stock at Gear4music.com.
Play a chord and the PolyTune will show you which strings are out of tune immediately.
Sounds like a useful gadget !
In ten years' time... a program that can transcribe an full orchestra ?
