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

given... Envelope e e.last() should return the current value generated. For Envelope class, it ought to be between 0-1 although for something like SinOsc, values range between -1 and 1. You could do e.last() * maxValue => float currentValue; It's still a little hairy, but a lot less logic than what you're doing. Also, in some circumstances you won't need the other shred. -Mike http://michaelclemow.com http://semiotech.org On Fri, Jul 13, 2012 at 2:57 PM, Jordan Orelli wrote:

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;

I understand the problem. Like this I have been using it for quite a while, but the need for the extra Step, unless it sets some sort of variable scaling, feels a bit counter-intuitive. I seem to remember it was Perry who first proposed that Envelope without any input should assume a input of 1. That would bring it more closely in line with similar objects in other systems.

There is also no problem with asking questions if you looked around a bit; the documentation is a bit scattered.
