# Unison Mode for instruments
Combine multiple AI instruments into a single unison track in ACE Studio.
## What is Unison Mode?
Unison Mode lets you combine multiple AI instruments into one AI 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 AI Instrument Tracks was called **Ensemble**.
{% endhint %}
## Turn Unison Mode on or off
To use Unison Mode, click Turn on Unison Mode in the AI Instrument Track panel. Turning Unison Mode off clears its settings.
### Add or remove instruments
* Click the + Add button to duplicate existing instruments.
* Drag new instruments from the Library to add them to the unison track.
* Arrange the order of instruments by dragging them.
### Edit parameters
* Spread: Controls the stereo width of the layered sound.
* Offset: Adjusts slight timing differences between instruments for a more natural effect.
* Gain: Sets the volume for individual instruments.
## 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 by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.acestudio.ai/instruments/create-instrument-sounds/unison-mode-for-instruments.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
