The software seeks a stable area of the sample and then artificially creates a loop. A sound segment is copied with a crossfade, so that the transition at the join location is as smooth as possible.

To assign loop points automatically:

• click in the tree on the sample to be looped,
• in the editing page of samples:
  • position the start and end of the loop in the graphic (WAV display area) around a stable area, or
  • let the tool determine automatically a stable area by defining 0 as loop start and loop end,
• in the "Tools" menu select "Sample", "Auto loop",
• press the Play button with the loop option checked,
• if the loop points found are not suitable you can undo the operation, try repositioning them manually around a stable area and then use the "Auto loop" function again.

If the tool is unable to find loop points, a warning message will appear. This can happen if a sample is not long enough or is too turbulent. The minimum sample length for the "Auto Loop" function to work is half a second, even if the sample is perfectly stable like a sine wave. If this condition is not respected you can still try to find try to find loop points manually.

Warning: This tool modifies the original sample. Modifications can be undone via the "undo" function, but if the file is saved and Polyphone is closed there is no way to step back.

Note: By default, the looping is disabled in an instrument. To hear it, you must enter a "1" in the Loop playback parameter row of either the Global or individual notes columns in the Parameters Table. "1" turns it On, "0" turns it Off. The value "3" turns the looping On and the sample will play to the end after the key is released.
