As the name suggests, FL Studio’s Echo Delay creates echoes from your midi input and allows you to manipulate the delays with volume, panning, cutoff and resonance, pitch and timing.
When Fat Mode is selected, this will create a chorus/unison type effect. This will allow you to add more movement and a more interesting overall sound to your selected instrument or sample, before you add any effects to the insert the channel is routed to in the mixer.
Echo Delay/Fat Sound is located under the Miscellaneous tab in the channel settings. When you click the drop-down menu, you’ll have access to 6 different presets to get you started, including 2 Echo presets and 4 Fat Mode presets. The echo presets will simply add a delay effect to your sound. The Fat Mode will add a flanger/phaser type effect to your sound.
The FEED knob will keep each delay the same volume as the input signal when it is set to 80%. It will fade out the delays when you set the knob lower or increase each delay’s volume when you set the knob higher than 80%. The PAN knob will move the location of the delays to the left or right side of the stereo field. Switching Ping Pong mode on will bounce the delays back and forth from the panning settings. MOD X and MOD Y are actually referring to the filter section of the channel settings. This is only available when using audio in a sampler channel.
This section is located in the envelope tab of the sampler channel. You’ll have 8 different filters you can choose from. MOD X controls the cutoff frequency and MOD Y controls the resonance. After you’ve set these initial settings, you can go into the Echo Delay/Fat Mode section and further manipulate your delays with the MOD X and MOD Y knobs. For example, increasing MOD X will increase the cutoff of each delay more and more as each delay plays. Decreasing will lower the cutoff with each subsequent delay.
The PITCH knob will increase or decrease the pitch of each subsequent delay up to 12 semitones. One of my favorite things to do with this knob is to pitch it all the way up or down to 12 so that each delay plays a new octave. Combining this with the TIME knob can make your original midi input much more musical.
The TIME knob will allow you to sync the delays to your tempo or whatever offset timing you’d like. It would be nice to have an auto sync tempo option here, but instead, you’ll have to use your ears to get the perfect timing.
The Echoes section is where you set the number of delays you want the signal to produce. You can have up to 10 delays this way. This will dramatically affect the Fat Mode option in terms of how dramatic the effect will sound. The more echoes/delays you add, the more of a chorus/unison type effect will be added to the voices. All of the knobs correspond to the number of echoes you set. So, the higher the number, the more these knobs will spread the effect out over time with each echo/delay.
If you haven’t already, give Echo Delay/Fat Mode a try on some of your sounds. This works especially well with keys, bells and plucks. Some of you might find that Fruity Delay 3 has very similar options to these settings, so give that a try as well. Both are capable of adding more interesting types of delays than your typical repetitive echo.
