Thanks again Michael but this brings along a lot of other questions:
- the difference between blackhole and dac. Can you use them together?
- SinOsc doesn't have ".last()" as a member eighter. Where can i find ".next()", ".last()" ... etc... and their use.
- If i refer to ".last()" in case of a sinewave does it give the last freq, sfreq, phase or sync member.
Kind regards,
Herman

Sorry, guess my email client needs a ChucK interpreter. ;)
lfo.next() should be lfo.last()

Hi Michael,
Sorry for all the trouble but when i do as you told me :
SinOsc lfo => blackhole;
0.5 => lfo.freq;
//…
while (true)
{
// ...
lfo.next() => pan.pan;
.....
Console tells me sinOsc doesn't have a member .next()
Kind regards,

Hello Michael,
Thanks a lot for your help. I don't know if i can reply to you with other questions or if i should use "chuck-users@lists.cs.princeton.edumailto:chuck-users@lists.cs.princeton.edu".
The ChucK mailing list is probably best.
In the meantime i found a solution for my "pause" problem in the use of ADSR. But i still have some general questions and some about the program that follows:
1. Where can i find a chuck editor with the possibility to find words and replace them (all) and that also gives the colors for reserved words etc.
Have you seen the miniAudicle? That is the official IDE for ChucK
http://audicle.cs.princeton.edu/mini/
I personally use a mode for Emacs to provide syntax highlighting
https://github.com/heuermh/chuck-mode
There is support for other editors out there; I seem to remember a wiki with links to such somewhere but I can't find it.
1. Is there a way to debug line per line to discover logical errors?
Not that I know of. My bit of advice is to not run a ChucK script with headphones on without trying it on speakers first. I learned that the hard way from a mis-configured filter.
1. i discovered by accident that sometimes i can use "p.puf" but on other occasions i have to write "p.buf()" why is this?
In general, to read from a function/value, use the version with params
p.buf() => float f;
To set a value, use the chuck operator into the version without params
1.0 => p.buf;
This is equivalent to making a single-argument function call (but the former is more ChucK-y)
p.buf(1.0);
1. in the program hereby, is there a way to have the pan do it's job independantely from the note-envelope-flow? to go faster or slower?
Yes, you can use an oscillator as an LFO modulator
SinOsc lfo => blackhole;
0.5 => lfo.freq;
//…
while (true)
{
// ...
lfo.next() => pan.pan;
If you want to update the pan at sample rate or at a rate independent from your main while loop, create a new shred
spork ~ _updateAtSampleRate();
fun void _updateAtSampleRate()
{
while (true)
{
1::samp => now;
lfo.next() => pan.pan;
}
}
Hope this helps!
1. When i run this program it does what i want but i can't figure out why it says 2 times "p.pan = 1.000000" and 2 times "p.pan= -1.000000" (see below)
Please let me know if i have to address all my questions to the general email address. thanks a lot !!

Onderwerp: Re: [chuck-users] Create a pause of e.g. 2 seconds between notes or samples to be played
Hello Herman,
ChucK supports advancing time by chucking a duration to now, e.g.
note.play();
2::second => now;
note.play();
LiCK (a Library for ChucK)https://github.com/heuermh/lick has a TimeSignature class, which provides static durations
TimeSignature.common(120) @=> TimeSignature ts;
note.play();
ts.q => now;
note.play();
and those that are dynamic to tempo changes, with anticipation and delay humanization
TimeSignature.common(120) @=> TimeSignature ts;
ts.quarterProvider() @=> QuarterProvider q;
0.1 => q.anticipation;
0.0 => q.delay;
while (true)
{
note.play();
q.get() => now;
ts.tempo() - 1 => ts.tempo;
}
Cheers!
michael

Hi,
I've only recentely started studiing ChucK and i'm looking for an easy way to integrate a pause between notes to be played in a "while()" loop. Could someone tell me in what direction to look for a solution? thanks in advance!
