Stereo Interleaved files generated by Third Party Audio Editors (such as Bias Peak and TC|Works Spark) will not appear with correct region information in Soft SampleCell 3.1. This is not an issue with Interleaved Stereo files generated by Sound Designer II, indicating that there is some resource information that is not written to the files.As a workaround the Interleaved file can be converted to Split Stereo, or it can be opened and then saved with Sound Designer II (which will then make the regions available).
