Processing : Elastic Audio : Editing in Warp View : Tempo Event-Generated Warp Markers

Tempo Event-Generated Warp Markers
Tempo Event-generated Warp markers are not editable and are only displayed to indicate where Elastic Audio processing has been applied to conform the audio to Tempo Events. You will only see Tempo Event-generated Warp markers on tick-based tracks.
If you change the track timebase from ticks to samples, any Tempo Event-generated Warp markers convert to regular, editable Warp markers.
