Oscillators of type (XXXOsc) do accept direct input
from other UGs for Phase or Frequency.  You just have
to set the .op mode for those.  In general, UGs don't
accept sample-rate ChucK connection for arbitrary 
parameters, as very often one doesn't really want or
need those to run at the sample rate.  Control rate is
arbitrary in ChucK, so to update the .freq of something
non-Osc type, you would make a shred that does it at 
your sub-sample rate. You could even do it at the
sample rate, of course.  Here's an example:

Flute f => dac;
880.0 => float freq => f.freq;
spork ~myMod();

1 => f.noteOn;

1*second => now;
660.0 => freq => f.freq;
1*second => now;
440.0 => freq => f.freq;
1*second => now;

fun void myMod() {
    SinOsc s => blackhole;
    6.0 => s.freq;
    while (true)  {
        freq * (1.0 + 0.05*s.last()) => f.freq;
        10 :: ms => now; // whatever rate you like here

// Cheers!!!  PRC
