If I accidentally click one of the arrows to connect functions, I can't get rid of the connection. If I put a line in I don't want I can't cut it or delete it. I put a blank transform in and typed both delay and Delay. Neither is recognized despite the audio/echo_machine example. Now I can't delete the blank transform. Sinewave isn't recognized in the transform either. I can't do anything now because everything creates an error message. I'd really like for this to work, but on several attempts have been totally unsuccessful unless I made no mistakes in my layout.
