Frequently Asked Questions
What is Pattern303?
Pattern303 is an unofficial pattern editor and librarian for the TD-3-MO. It lets you edit patterns on a clear visual grid, organise and back up your pattern library, and send patterns to and from the hardware. A built-in synth and kick let you preview patterns in real time, with or without the TD-3-MO connected.
Is Pattern303 made by Behringer?
No. Pattern303 is an independent, unofficial tool developed by Ajja Sonic. It is not affiliated with, endorsed or sponsored by Behringer or Music Tribe. TD-3-MO is a trademark of its respective owner.
How do I install Pattern303?
Download the installer for your platform from the download page. Run the installer, then scan for new plugins in your DAW.
Do I need a TD-3-MO to use it?
You need a TD-3-MO connected over USB to load patterns from the hardware and send them back. Editing patterns, managing your library and previewing with the built-in synth and kick all work without the hardware connected.
What DAWs are supported?
Pattern303 works with any DAW that supports AU or VST3, including Logic Pro, Ableton Live, Cubase and Bitwig. It runs natively on Apple Silicon and Intel Macs.
How does the free trial work?
The trial is fully functional for 7 days with no restrictions. No credit card or account is required — just download and install. After the trial expires, you'll need to purchase a license to continue using the plugin.
How many machines can I activate on?
Your license allows activation on up to three machines. You can deactivate a machine at any time from within the plugin to free up a slot for a different machine.
Can I move my license to a new computer?
Yes. Open Pattern303 on the machine you want to deactivate, go to the license settings, and deactivate it. Then activate on your new machine using the same license key.
Do I get free updates?
Yes. Your license includes all updates within the current major version at no additional cost.
What is your refund policy?
We offer a 14-day refund policy from the date of purchase. Since a fully functional free trial is available, we encourage you to evaluate the plugin before buying. See our Terms of Service for full details.
