Some questions concerning IO

[NeKro_Phyl]

Well, some new questions from your humble chuck novice...

As I count myself to the people who don't completely hate music like Power Electronics and because a Noise Generator is not the most complicated thing to encode (and because you can always need some noise ), my first chuck Program was a tunable noise - gen, based on an example prog in the chuck tutorial:

// make our patch
SinOsc s => dac;
30.0 => float l_f;
1000.0 => float h_f;
// time-loop, in which the osc's frequency is changed every 100 ms
while( true ) {
1::ms => now;
Std.rand2f(30.0, 1000.0) => s.freq;
}

Ok, the idea is that you can control l_f and h_f. One attempt could be from the command line. So, lets name our Program Noize.ck. One cool thing would be if you could control the frequencies with sth like

+ Noize.ck::30.0:1000.0

but there's my prob that Chuck doesn't accept the strings as floats. So, is there a function like string -> float?

Another Idea would be that you specify in the cmd Line the Keys with wich you can Modify the difference between and/or the absolute values of l_f and h_f. So, my Plan is that if you type:

+ Noize.ck::30.0:a:s:1000.0:b:f

the Program starts generating a Noise with l_f=30.0 and h_f=1000.0, but with a & s you can modify l_f and with d & f h_f.

Any tips how I have 2 implement it?

Thx

Answers can be found so easily...

Why don't use the on the fly-concept? So rigt now I change everything I want in the code and load the updated version in the VM...

So now my Prob changes to tune emacs a little bit, but that has to be discussed on another Forum...
