# Unison Mode for instruments

## What is Unison Mode?

Unison Mode lets you combine multiple AI instruments into one instrument track.

You can save your custom unison presets to the Instrument Library. Several pre-made presets are also available.

To use a unison preset, drag it to the canvas or onto the track header.

{% hint style="info" %}
In ACE Studio 2.1.1 and earlier, Unison Mode for instrument tracks was called **Ensemble**.
{% endhint %}

## Effects for Unison Mode

If you want to create a sense of space, use reverb or other effects in the FX chain.

To learn more about effects, please refer to [Effects](/project/mixing/effects.md).

## Save as a Preset

In the track panel menu, you can save the current unison setup as a preset. You can customize the preset's name and tags for easy retrieval. Your preset is saved in the Unison tab of the Instrument Library.

The presets you save will be stored in the cloud and linked to your account.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.acestudio.ai/ai-instruments/create-instrument-sounds/unison-mode-for-instruments.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
