I did a search on this. Others have had the problem but there was no satisfactory answer given.
I am using GS2.54
When I import samples the looping is turned on with loop points set to the beginning and end of the waveform. Awave says there is no loop. Turning off an individual sample is no problem but it doesn't appear one can select multiple samples and turn off looping all at once.
I am trying to avoid having to click the mouse three times (select sample, turn off, apply) in a worse case scenerio of 88 samples per layer.
