While running the GS 3 editor, I edited a non-looped instrument in the external wave editor Sound Forge 6 and made all the samples looped. And after that I saved and reloaded the instrument in the GS editor but the loop doesn't become effective at all.
All the loop parameters(loop start , loop end...)in the editor remain zero.
However opening the samples in Sound Forge shows that they are certainly looped.
Could anyone advise me how to make the loops efective in GigaStudio?

Thanks in advance,
