Download, install & activate all your purchased plug-ins from a single, intuitive place and start producing music right away. The UJAM App automatically activates your installed plug-ins for you – and if you need to uninstall plug-ins for some reason, we now offer that in the App as well.


The UJAM App always keeps you up-to-date, you will find all available updates in one screen. With the App you quickly and easily perform updates for all your installed plug-ins.

Start free trials

With monthly releases, we regularly add new plug-ins to your App. Install every plug-in from a single, intuitive place and start a free, 30 day trial without restrictions. The App keeps track of your remaining trial days. You can always buy plug-ins via the App if you like them, they will be activated automatically so you can start making music without re-installing.

Current version:

v0.3.16 (1790)


v0.3.16 released February 7, 2022: We fixed a bug that could cause the trial version to end immediately after activation. This App version also helps UJAM plug-ins to authenticate correctly on certain hardware configurations.

v0.3.15 released February 3, 2022: Fixed detection when an external drive was not connected as a download location (macOS only).

v0.3.14 released February 2, 2022: The App uses an improved authentication system and it notifies you about an unplugged external drive if that caused download failures. We recommend to update to this version if you had to sign back into the App every time you launched Usynth or Virtual Pianist.
