Alternative Looping Modes
Several samplers have different looping modes other than the basic Loop Forward mode.
If the destination sampler does not support one of these modes, Translator compensates by altering the sample data to exactly simulate the loop as specified. (The exception would be multiple loops, if the destination does not support them.)
There is also an option called Always Alter Loop Data in the Options-General Tab where Translator will alter the sample data even if the destination supports that type of loop. The reason you might want this is if you are converting, say, Ensoniq to Reason, and you want the WAVE/AIFF files to accurately reflect in-and-of-themselves what the loop really sounds like.
Regarding Loop+Release loop mode, where a loop exists only before the note-off command, and the remainder of the loop at that point of time and the rest of the data is played, is only supported between samplers that support it (which are Akai, Ensoniq, and Roland). Otherwise, it is translated as a simple "forward loop."
