WAV files can ... here's how ... I'm using Cool Edit 2000. 1. Load your audio file. 2. Select the area you want to loop 3. Menu: View -> Sampler Info 4. Click "New" (sampler loop) 5. Set the loop parameters (sustain, etc) 6. Press OK. 7. Save it as a WAV file 8. Open a sampler channel in Fruity. 9. Use the folder icon to open the wave file 10. If all is well, you'll see the entire waveform and you'll see two red lines showing the loop area 11. Make sure 'use loop points' is on That's it! Interesting to note that on a "note on" message Fruity will play from the beginning of the sample, not the beginning of the loop, but once it's played to the end of the loop will return to the start of the loop, not the start of the sample. It's a pity that upon releasing the note it doesn't keep playing to the end of the sample, that would be quite useful - but instead, if you've set the envelope up with a long sustain it just keeps playing the loop until it fades out.
