I have been working on Vegas for almost a year now but I still have no idea on how to do an echo effect without the effect cutting off at the end of the audio. Also, volume doesn't work, the effect also gets carried too. Any ideas on how to reslove this?
Audio FX which would cause the audio to be longer than the timeline event need to be used as Track FX, Bus Track FX or as Non-Realtime FX. Anything you apply to an timeline event won't be longer than the Event itself.
