TOPIC: Problem: Returning to polyphone a stereo audio .

Hi.
When returning to polyphone a stereo audio of an instrument, -already reedited in an audio editor-, the original processed sample is not substituted.
The program interprets the old sample with a sign "* - L" or "* -R", and the new one reads it "* L" or "* R".
Can I change this?

Resolved:
1.Rename all and rename samples massive: replace: "-" for ""
2. Export samples.
3. Edit samples.
4. Reimport samples edited.
5. Remplace.
