Displaying Envelopes



There can be literally dozens of different envelopes that are applied to a piece of music. For each track there might be volume and balance, possibly reverb and chorus effects. For 8 tracks this totals 32 different envelopes, not including tempo or master volume. The controls at the bottom of the Envelope View areUsed to divide envelopes into specific categories and types. In addition, the controls at the top of the window may affect which envelope is displayed in the Envelope View.


The Envelope Category box displays several categories. Depending on which category is selected the Envelope Type box may or may not be activated.


The table below summarizes the behavior:
