[chuck-users] interpolated step? (equivalent to max's line)

[Jordan Orelli]

there's no way to use this to ramp an arbitrary variable, like the frequency of a SinOsc, for example, is there?  Cause I do stuff like this and find it kinda annoying: 

SinOsc s => dac;
110 => float initial => s.freq;

fun void ramp() {
    880 => float final;
    1::ms => dur res;
    500::ms => dur width;
    (final - initial) / (width / res) => float delta;
    now => time start;
    while(now < start + width) {
        res => now;
        s.freq() + delta => s.freq;
    }
}
spork ~ ramp();

1::second => now;
