Friday Tips: The Melodyne Envelope Flanger

This isn’t a joke—there really is an envelope-controlled flanger hidden inside Melodyne Essential that sounds particularly good with drums, but also works well with program material. The flanging is not your basic, boring “whoosh-whoosh-whoosh” LFO-driven flanging, but follows the amplitude envelope of the track being flanged. It’s all done with Melodyne Essential, although of course you can also do this with more advanced Melodyne versions. Here’s how simple it is to do envelope-followed flanging in Studio One.

  1. Duplicate the track or Event you want to flange.

  1. Select the copied Event, then type Ctrl+M (or right-click on the Event and choose Edit with Melodyne)
  2. In Melodyne, under Algorithm, choose Percussive and let Melodyne re-detect the pitches.

  1. “Select all” in Melodyne so that all the blobs are red, then start playback.
  2. Click in the “Pitch deviation (in cents) of selected note” field.
  3. Drag up or down a few cents to introduce flanging. I tend to like dragging down about -14 cents.

As with any flanging effect, you can regulate the mix of the flanged and dry sounds by altering the balance of the two tracks.

Note that altering the Pitch Deviation parameter indicates an offset from the current Pitch Deviation, not an absolute value. For example if you drag down to -10 cents,  release the mouse button, and click on the parameter again, the display will show 0 instead of -10. So if you drag up by +4 cents, the pitch deviation will now be at -6 cents, not +4. If you get too lost, just select all the blobs, choose the Percussion algorithm again, and Melodyne will set everything back to 0 cents after re-detecting the blobs.

And of course, I don’t expect you to believe that something this seemingly odd actually works, so check out the audio example. The first part is envelope-flanged drums, and the second part applies envelope flanging to program material from my [shameless plug] Joie de Vivre album. So next time you need envelope-controlled flanging, don’t reach for a stompbox—edit with Melodyne.

    Hello, I am wodering What is the ADT?
    PS. Ah Ok, It is Artifical Double Tracking. I used Melodyne to create this effect.

    The more I dig into Melodyne, the more I find it can do things I didn’t expect (and probably weren’t intended, LOL). For example it can also do some really good and natural-sounding ADT effects, sometimes better than ADT plug-ins. That might make for a good tip too.

  • I’ll have to give it try sometime. I never thought of using Melodyne for that.

    Compare the two approaches, you’ll hear the difference. The Melodyne option follows the envelope more closely; the speedup option is the traditional flanging caused by detuning. The difference is due to the way Melodyne creates blobs during analysis, instead of treating the waveform as a continuous file.

  • You can do that on the audio track within S1 without using Melodyne, simply right click on the track and the options are there to transpose by half steps or fine tune up or down by cents.
    I use this frequently for thickening vocal and guitar tracks. One of the things I like to do is duplicate a vocal or guitar track so I have three tracks, tune one track +1 pan it to the right, another -1 pan it to the left, put the X-Trem plug in on the original track in panning mode and gently pan between two slightly detuned tracks.
