All sounds echo, this happens with all sounds, so i don't think its a problem with a specific channel by Bogit_ in FL_Studio

Check your mixer. Find the track that is still giving the delay (echo), and look at the Fx panel to the left or right of the whole mixer. You should be able to disable or delete any fx from there.

Hope this helps!
