Play Burst (Single, Repeat)

Controls: Gen Dlg >> Stream >> Wave >> Play >> Burst
Macro: PlayBurst

If you use the Play wave with the Burst modulator, this control tells what to do when the selected (From to To) region is shorter than the total Burst duration. When set to Single, the burst will only play the selected portion of the file once per burst; the remainder of the burst will be filled with zeros. When set to Repeat, the selected portion will be repeated throughout the entire burst.

If you only want a single, non-repeating burst each time you toggle the Generator on, use Single here and set Burst Cycle to a very large value such that it won't repeat during the time the Generator is running. Entering 5G will force Burst Cycle to its maximum value of 2^32-1 samples, or 89478.48530 seconds at a sample rate of 48000 Hz... over 24 hours.


Macro Notes:

L.1.PlayBurst=Rept or L.1.PlayBurst=1 sets Burst Repeat for Left Stream 1. PlayBurst=Sngl or PlayBurst=0 sets Burst Single, and PlayBurst=x toggles between the two.
