A Guide to FL Studio's Fruity Delay
Fruity Delay is what will give any sound that feeling of slowly fading away. It works great on vocals when you want a line to repeat for emphasis. You can automate the controls here, too, and have the tempo increase while the volume drops so that the voice repeats faster and faster while dropping in volume. Putting delay on instrument pieces such as a hi-hat can produce an exciting backbeat that is better than what you initially made.
The Input knob will affect the volume of the original sound and how loud it plays into the plugin. Feedback is the volume of the echoes created by the delay. Be careful because turning Feedback up will cause the echo to repeat endlessly. Consider that this could be used to create the song's rhythm with just a constant repeating sound and then automated to stop repeating at the end of the song. There are many creative ways to utilize this plugin.
Similar to other plugins, the Cutoff will affect the frequency of the echoes that come out of Fruity Delay. Tempo, by default, is set to Auto so that the echoes will automatically lock to the tempo. Tempo, by default, is set to Auto so that the echoes will automatically lock to the tempo. This is usually the desirable setting, so everything is crisp, but feel free to change it and try automating it because many different types of music incorporate specific tempo-synced delay for interesting percussion and melody.
Steps will affect how often the echoes play, and Mode will affect the stereo image of the echo. The Normal settings play the output like the original and Inv. Stereo will swap the left and right channels so that the right channel will echo on the left and vice versa. Ping Pong will alternate between using the left and right inputs to echo, so if you have a constant hi-hat in the left channel, it will still play in the left channel, but it will echo in the left, then right, then left, and so on.
