Frequently Asked Questions

How do I install CUBE?

For a full walkthrough and installation videos please see the page Getting Started With CUBE

After downloading the product, first run the installer for the plugin and then the installer for the samples.

The plugin installer will install the factory presets and all of the plugin files (VST, AU, AAX, Standalone) in their default locations.

The sample installer will install the CUBE samples in a custom location, which you can set when installing. We recommend installing the samples on an external SSD drive for best results.

Where is my download / license key?

After purchasing CUBE, you should receive an e-mail with links to download the CUBE engine and samples. Please be sure to check your Junk / Promotions folders for e-mails from Lunacy Audio. Once CUBE is installed, you can use the license key found in the CUBE purchase e-mail to license the plug-in. Downloads and Licenses can also be found by logging in and visiting your Lunacy Audio accounts page. Login or create an account here.

My license key isn't working. How do I activate CUBE?
First, try activating CUBE from the standalone version. You can find the standalone version here:


Standalone: /Applications/Lunacy Audio
Standalone: C:\Program Files\Lunacy Audio\CUBE

Next, make sure you have a solid internet connection and you are not using any VPNs or IP blockers.

If you still cannot activate CUBE after trying the above, please send us a support ticket and we’ll set up a manual activation for you.

Can I use my CUBE license on more than one machine?

Yes, each purchase of CUBE allows you to use your license on up to 3 different machines.

CUBE can't find the samples. How do I get CUBE to see them?

During Sample Installation, you can choose the installation destination, where CUBE will install the samples. If you did not choose a custom installation destination, check in the default installation location here:

Samples: /Users/Shared/Lunacy Audio/CUBE/Samples
Samples: C:\Program Files\Common Files\Lunacy Audio\CUBE\Samples

You can also change the sample folder location after installation by opening CUBE’s settings and clicking the “Change Sample Folder Location” button in the Engine tab.

Can I add my own samples to CUBE?

Yes! You can drag and drop any sample, wave file or SFZ,  onto any corner of the full version of CUBE. The Mini version does not include user audio.

Why is my CUBE audio crackling or choppy?

If you are on Windows, be sure to use a dedicated audio driver and not the default Windows Audio Driver, whic may result in choppy audio.

You may also want to adjust your buffer size to be a multiple of 8. Try changing your buffer size to 256, 512, or 1024. CUBE is optimized for standard buffer sizes.

What is your refund policy?

If you are not satisfied with your purchase for any reason, you are eligible for a refund on any software products up to 14 days after the purchase has been completed. Due to the nature of digital downloads, we cannot offer refunds on CUBE expansion packs, only software. If you purchase any bundles, only the software portion of the bundle will be refundable.

We do require that you successfully deactivate the product on your machine prior to requesting a refund. This ensures we’re able to process your return as quickly and effectively as possible.

To request a refund, please submit a ticket by clicking the button below.

Do you offer an educational discount?

Yes, we offer a 50% educational discount for all eligible full-time students and teachers at accredited institutions. Please submit a support ticket with documents either showing proof of enrollment / employment or a valid student / teacher ID.

Need to Register a Product?

If you purchased CUBE through Plugin Boutique or Loot Audio, please log in here to register your license key.

If you don’t have a Lunacy account, you can register both your license key and account here.

No Sound from CUBE?

First, please be sure you are using either a MIDI keyboard or Digital Audio Workstation (DAW) with CUBE. CUBE cannot produce sound on its own and needs MIDI input.

Second, please check that you are using a proper audio driver and buffer size. We do not recommend using the default Windows Audio Driver and CUBE requires a buffer size that’s a multiple of 8 (like 128, 256, 512, 1024, etc).
