M4L Delay On Steroids

Delay, and Beyond

In short: Alter Echo is a super delay.

What does a super delay do? Well, it delays signals with incredible accurate tools, and it offers a set of crazy manipulation parameters.

That’s Alter Echo!

Alter Echo is the most creative delay you can use in Ableton Live. Thanks to a wide range of parameters in four sections: what sequencer, texturize, when sequencer, and side-chain compressor. It does great job as classic delay, and it brings a lot of innovative uses!

Alter Echo lets you delay a signal, exactly how you want. Then, it goes beyond and it lets you shape the delayed signal with exclusive advanced features.

This delay effect will take your sound to a next level, into unexplored textural vibrations, complex accents configurations, continuously moving rhythms, and more!

  • Unlimited Time Resolutions – All the time resolutions that you may need
  • Link or Unlink? – Edit both channels at once, or unlink for exclusive settings
  • What + When – Define what audio should be delayed and when it should be played
  • Sidechain Compression – Handle dry/wet amplitudes, creatively
  • Shaped Envelopes – Design how to feed the delay: step by step, shape by shape
  • Texturize – Experiment with crazy sound manipulations on delayed signal!

How It Works

In Alter Echo, the signal is sent to the delay circuit via the exclusive what sequencer. This tool allows you to choose exactly what part of the incoming audio you want to delay, managing its amplitude, also with fade in and fade out. This works from simple contents up to very rich and intricate configurations: you get up to 16 steps, accurate shape editing tools for each step, all-time configurations you want (4/4? 7/8 triplets? 3/4 dotted? 7/32? 31/4? You can use them all!).

Once you’ve chosen how to feed the delay, you set delay time. Delay time works in ms or note values; again, all the time configurations are available as for the what sequencer, for infinite possibilities.

The audio goes then through a low-pass/high-pass filter, and then in the texturize panel. This panel offers tons of handling parameters. Everything is based on the texturize length. This is a different value from the delay time, and here’s the big difference with other delay effects. Often, in a delay effect, you get reading directions, but for example, if you select “backward”, you’ll get backward segments equal to delay time. Delay time is 1/4? Then you’ll get 1/4 reversed slices. In Alter Echo you keep these functions as independent values: you can have a short 1/64 delay, and long 1/4 forward and backward slices, for a liquid and smooth shortly delayed wet signal. The same is for all parameters of this section: you can apply amplitude envelopes, split the playhead in two, and move the second playhead to create stunning accent configurations or set the repeat chance to enrich the dry signal with a partially rearranged and delayed wet signal. This is so cool!

The wet signal is finally sent through the when toggle sequencer. It handles the amplitude of wet signal thanks to the interpolation parameters, going from a fast vibrato, up to unexpected breaks, and more.

Then dry and wet signals are sent into the side-chain compressor. That’s definitely the best way to handle wet and dry amplitudes dynamically based on the content. And last but not least: a separate dry/wet mixer is a must to fine tune your vibes!

We keep usability as the main purpose in all our devices, and Alter Echo offers useful tools in this way: a stunning display, available in audio or in infographic modes, the compact view mode, to save space in the channel strip keeping an eye on what Alter Echo is doing, the unlink mode, to expand the Alter Echo interface and edit both channels with exclusively.

Alter Echo will become your favourite delay, even if you need it on loops, to play live with your instrument, for classic delay use, or inedited delayed madness!
