Hello. Can someone tell me what envelopes are and what they do? I know they change some properties of the sound, but they have some default, like: Envelope A changes this, Envelope B changes other things etc.?I'm sure you're talking about the basic ADSR envelope. Attack, Decay, Sustain, Release.
Attack is the initial volume control when playing a note, as well as how long it takes for the note to reach it's peak volume. Shorter attacks are for quicker notes while longer are for notes with a "fade in" like pads or strings. Decay is the point going from it's maximum to the level of the sustain. Sustain is the volume when the note is held, and release is the "fade out" of the note.
I would like to go even further and move into Sytrus-like envelopes, or other envelopes that don't control volume. The general focus of envelopes is on when that particular note is played. That said, some envelopes control the cutoff of a filter, the depth of the chorus, or pretty much any control that the program allows you to link to the envelope. And there are more advanced envelopes than the ADSR envelope, such as the one on Sytrus. That one has ASDR features, but it has so much more too! I don't know what to call it, I guess one would call it a drawn envelope. The sustain part is actually looped so that part can oscillate between levels. Furthermore, the release part has much more flexibility than just a fade/click out. You'll have to play with that envelope to know what I'm talking about.
And other thing, there is a way to change de tempo while the song play? I want say: at 00:00 - 00:10 the tempo is 140, at 00:10 - 00:40 the tempo is 160, and then the tempo change back to 140?Doing that requires using a automation clip in the pattern roll to set the tempo to those speeds, it could be instantaneous or it could be gradual.
That's one way to do it, but a better way to do it that allows you to pick and choose the tempo much more precisely is to go to an empty pattern selection, right-click the tempo selector and click "edit events". Once you get to that screen, you can either draw a sequence for the tempo change i.e. a gradual rise or gradual decrease or you can hit the pencil tool and click the first box for immediate drastic tempo change. Then place that tempo change as a pattern in the playlist anywhere you want.
A smart move to do before any of this though is to select a tempo that you want at the beginning of the song, right click the box with the tempo and hit "initiate song with this position." That way, the tempo always goes back to normal each time the song loops.
