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!!!
