[sc-users] Pitch tracking

[Peter O'Doherty <mail@xxxxxxxxxxxxxxxxx>]

Hi,
I have a couple of questions concerning Pitch. Using the code below I 
get the frequency and midi information in the following format:

freq: 440
[ /tr, 1001, 69, 440 ]
freq: 272.809
[ /tr, 1001, 60, 272.80856323242 ]

Is there any way to "trim" this to print only freq and midi in a form 
such as: 440 69 ?
Is there any way to store the polled frequency information to allow it 
to be exported to, for example, excel?
Is it possible to convert the "copy" channel to a midi file, including 
attack info?
(Yes, I'm looking for a method to created a rough transcription of an 
audio file.)
Thanks,
Peter

(
SynthDef("pitchFollow1",{|t_poll = 0|
    var in, amp, freq, hasFreq, out, original, copy;
    in = PlayBuf.ar(1, c.bufnum, loop:0);

    # freq, hasFreq = Pitch.kr(in, ampThreshold: 0.01, median: 7);

    original = PlayBuf.ar(1, c.bufnum, loop: 0) * 2;
    copy = SinOsc.ar(freq, 0, 0.2);

    Poll.kr(Impulse.kr(10), freq, "freq", freq.cpsmidi, "midi");
    Out.ar(0, [original, copy]);

}).play(s);
)
