Welcome to the group Adam. The first step in recovery is admitting that 
you have a problem



We do have a bug/feature request line on our sourceforge page, ( 
http://chuck.sf.net )
this forum's also good for requests.

I made some very basic runs at this, but it's about as illuminating as 
parsing out raw midi from ints can be.
MIDI's very minimal now, we'll have richer functionality ( and examples 
) once objects/events are on the scene.

The STK Envelope or ASDR classes are about as far as we go for 
breakpoints.  Those only support
linear interpolation. Envelope is not so pretty to code at the moment,
but with arrays/objects we'll have wider range of options ( more like 
vline of pd or max/msp )

sinosc s => Envelope e => dac
0.10::second => e.time;
1.0 => e.target;
0.10::second => now;
0.5::second => e.time;
0.2 => e.target;
0.5::second=> now;
...etc..

This would be cool.   At the moment, the oscillator classes can be 
driven by audio-rate control value (check out sixty.ck ) .
but that's not quite what you're looking for.  Again, objects/arrays 
would simplify this
In the meantime, you could drive a loop at sample rate and use the 
ugen.last function to DIY

	(float) intval => ugen.floatfunction;
	(int) floatval => ugen.intfunction;
