[chuck-users] CurveTable example...?

Hello, ChucK people - How do I use CurveTable? I've tried chucking a SinOsc to it as one would an envelope, but that didn't work. I've also tried this: SinOsc s => Gain g => dac; CurveTable t; [0.0, 0.0, 0.0, 2.0, 1.0, 0.0, 3.0, 0.0] @=> float times[]; times => t.coefs; while (true) { 1::samp => now; t.last() => g.gain; }; thanks, jascha
