I can't hear the first note that I play only the repeats from the delay. What is the problem with the Flashback / Alter Ego?
This happens when your Flashback / Alter Ego is set to 'kill-dry on' mode. It should be set to 'kill-dry off'.
To solve this issue you will to remove the bottom plate to change this setting. Once inside you will see 2 dip switches. Please see the diagram below and set it to 'kill-dry off'
