The Process Window is displayed whenever a preview is requested or the final wave file is being generated.
The top of the window displays the current command, track, and beat as they are processed.
The Messages box will display any warnings if there is a problem loading a wave file, handling the data, filtering the sound, and so forth.
After processing ends, the time taken will be displayed in seconds. Additionally, the length of the preview file or final wave file will be displayed in bytes, samples, and seconds. It is important to note that previews will trim excess trailing silence and that the lengths shown are for the preview and will not be the same when used in the final wave file.
At the bottom of the window are a few buttons. The play, pause, and stop buttons are used to listen to the preview or final wave file. The Reset button acts both as a rewind control and to close and re-open the file being played in case there is a problem. The Cancel button will cancel processing as soon as the current command has been completed. The Done button closes the Process Window.
