Alright. The OSCresponder and SendTrig combination is probably the
most simple. The only disadvantage is that you can only receive one
value at a time (I think...). For me this was a problem because I did
pitch analysis and had to put the pitch and the amplitude of a note in
a database at the same time, but if the only thing you want to do is
to put some single values in an array it works great. So a little code
example might look like this:
~input = Array.newClear(20); //Array to put the UGen values in
(
var count;
count = 0; //Initialize counter to 0
o = OSCresponder(s.addr, '/tr', { arg t, r, msg;
//[count, msg[3]].postln;
~input.put(count, msg[3]);
count = (count + 1) % ~input.size; //Increment the
counter, but wrap it between 0 and size of your input array minus 1
}).add;
//Some SynthDef were you want to poll the values from
SynthDef.new("detectPitch", { arg trigID = 1;
var input, freq, hasFreq, amp;
input = SinOsc.ar(440, 0, 1); //A source
amp = Amplitude.kr(input);
# freq, hasFreq = Pitch.kr(input, ampThrehold: 0.02. median: 7);
freq = freq.cpsmidi.round(1);
SendTrig.kr(Impulse.kr(5), trigID, freq); //Increase the
rate of Impulse to achieve more precision. Further note that you can
send an array like
//[freq,
amp] but that OSCresponder will 'unpack' the array into 2 separate
values so you can't use it
//to
write 2 values into an array at the same time.
}).send(s);
)
The solution with a Routine is maybe a little more complicated, but
then you can put more than 1 item in a database at the same time. I
hope you can do something with this and if you would like to know more
about the Routine solution let me know, then I'll post a little
example of that one too.

Ah! Michael, a code snippet is worth a thousand nodes. Please do, and
thanks! Sounds great.

I have been working on the same thing bassically. I came up with 2
solutions. 1 indeed by using OSCresponder and SendTrig, but
actually the one I ended up using was to just use a control rate
bus to send my Ugen data to and then I build a loop with a
Routine that accesses the bus with the .getn message and stores
the data in an Array with a counter that gets incremented each
time through the loop.
If you need more specific code, I can put up a short example.
Good luck,

Take a look at OSCresponderNode and SendTrig. This would probably
be the easiest way to do it (and access the values in the lang).
Best,

Hi, I am wondering how to fill an array with the output of a
control rate from a unit generator, possibly at pre-determined
intervals [every 2nd, 3rd or 4th value]. Possibly a function
that uses a ugen to return an array? I can't seem to achieve
this on my own...
