FX envelopes

Volume and Pan envelopes (as well as FX envelopes) are track-level envelopes— that is, they run across an entire track, affecting every event in that track. Individual events can also be quickly faded in or out using event fade envelopes, otherwise known as Attack-Sustain-Release (ASR) envelopes. To create an event fade, move the mouse cursor over the upper (left or right) corner of an event. The cursor changes to the special event fade cursor (see Figure 4.4). Drag the fade envelope in towards the center of the event. 

You must right-click the Multipurpose Fader Mode button and select FYe Volume to use the Volruue aud FX feder to adjust the Dry/Wet mix. Yes, this is the same as the previous Note, but it is easy to forget, aud the FX fader and FX envelopes won t work if you dou t do this. 

Assignable FX also let you use FX Envelopes, which automate the gain over time of the FX in exactly the same way that the Multi-purpose Fade allows you to set the gain. Using both Volume and FX envelopes, you can animate the Dry/Wet mix over time. 

Envelopes are color-coded in ACID red = volume, purple = pan, and blue = FX. 

In Figure 2.32, to make the illustration more clear, no events are visible in the track. In an actual project, an event would also be inserted somewhere in this track to take advantage of this rather artificially complex tangle of envelopes. Without an event, there is no output from a track and therefore no reason to automate the volume, panning, or FX with envelopes. To use envelopes, right-click on a track and, from the context menu, select Insert/Remove Envelope. Then select the type of envelope to insert or remove (e.g. Volume). 

One great advantage to using busses this way is that you can use envelopes on the track to animate the level of the effect over time in the project, much like you use Volume or Pan envelopes. Assignable FX also share this advantage as well. 

To use envelopes to animate the mix of the effect over hme, right-click the blank area of the timeline in the track you want to use envelopes in and select the Assignable FX from the list (for example, FXl). Double-click the envelope to add a node and then drag the node up or down to adjust the gain. The plug-in effect is mixed with whatever the Volume is set to, so use a Volume envelope to further adjust the total mix. 

Generally, the instruments in this region consist of four chambers the source area, the filter area, the monochromator, and the detector area. The source area will house the source and choppers it can also include the filters [ ]. In the Perkin-Elmer Model 201 (single-beam) [ ] and Model 301 (double-beam) [ ], the source area houses the source and the choppers. The source used in these instruments is a globar from 25 to 100 fx and an H-4 mercury lamp (envelope removed) from 100 to 200 /i. Miller uses a globar from 33 to 200...
