A Multi-tap echo [delay](https://en.wikipedia.org/wiki/Delay_\(audio_effect\)) plugin.

## Graphs

* **Green Graph**:
  * **X axis:** displays number of steps (think "echoes") in chronological order.
  * **Y axis:** displays volume (in dB) of each successive step.&#x20;
* **Blue Graph**:
  * **X axis:** displays number of steps (think "echoes") in chronological order.
  * **Y axis:** displays lowpass cutoff (in Hz) of each successive step.
    * There is a lowpass filter applied to each step, whose individual cutoffs can be altered.

{% hint style="info" %}
You can draw on the graph with `Left Click + Drag` to set volume/lowpass cutoff for each step as desired.
{% endhint %}

## Knobs

* **Length:** adjusts the amount of time that passes between each step.
* **Dry:** adjusts the gain of the Dry (unaffected) signal.
* **Stages:** adjusts the number of times each step goes through its lowpass filter.

## Other

* **Number box** (<img src="broken://files/-MPVAjylP3ZXIYIHBzFI" alt="" data-size="original">): adjusts the amount of steps that occur.
* **Swap inputs:** swaps Left/Right input channels (can be used to create rich stereo fields), this does not swap the Dry signal's output channels.
