how does this place tolerate absolute beginner questions? |

hi everyone, I'm a longtime modular synth user. I recently got into using the nord G2 and then into Reaktor, and was really impressed by how much more I was able to do with emulations and software versus analog hardware.
I decided to take the leap and get supercollider, I can already see theoretically many things that I will be able to do with this software that will prove very useful to me (stipulating exact frequencies for oscillators is a big one) but I am having such a hard time getting it to do what I want. I have been going through the help file tutorials and trying my best but often the various functions are talked about as separate things, and when it comes to combining them there is no help. I am a 100% first timer when it comes to writing code, I have never even done simple html stuff. I am comfortable with math and logic, so I assume that it's not beyond me.
My first simple question is this: why can I not figure out how to apply an envelope to a sound? I tried putting an Xline on the multiplier of a SinOsc, no go (although it works to put the same thing on the frequency number?) I looked up envelopes in the help file and there are examples of envelopes, but no help as how to apply them to other sounds.
Any help, or even a bit of consolation would be appreciated, this stuff is hard! |

Beginner questions are absolutely welcome, but I should say I don't see a lot of supercollider users on this board so it might take longer to get an answer here than it would elsewhere.
One thing that helps to get an answer more quickly is if you post the code. Without looking at the code, readers can only guess what the problem might be. Also a precise description of the symptom is helpful - "tried this, no go" is hard to diagnose because it doesn't say what actually happened. "Tried this and my speaker fried with horrible distortion" or "tried this and it was totally silent" are more descriptive. (My day job is in tech support, and if I had a nickel for every time a customer said "I got an error" without saying what the error is, I could retire today.)
If I had to take a guess, I would suppose that one of your endpoints to the XLine might have been 0. Since it's an exponential curve, neither endpoint can be zero and both have to have the same sign. If not, seems that XLine fails silently and returns 0 throughout.

0.001 = -60dB, commonly considered a practical zero-point.
Feel free to ask other questions -- however, it seems like not many people other than myself answer questions on this board, and I'm going to be out of the country for a month starting later this week, not sure of Internet accessibility. So you might consider looking at one of the other supercollider community resources.
