Hey, I'm preparing the closed beta of Morningdew JORNA hybrid synth. If you wanna take part of the beta testing and try out this synth before everyone else (I've got around 30 slots for the test).

The JORNA synth v0.9.0 (beta) will be fully functional without any restrictions for 10 days, so we can test it properly! Oh, this 1st beta is MAC OS only with CLAP, AU and VST3 plugin versions! Win beta will be later down the line (no date yet, as I'm porting the GUI as we speak).

Important - Before you apply to the beta test:
---------------------------------------------------------------------------
***This 1st test round is MAC OS only!**

* I've got 30 slots for the closed beta if you want in!
So hurry up if you wanna take part!

* CLAP, AU and VST3 formats included in the installer.

* There is a bundled WIP content pack attached to the plugin with some presets, samples and multisamples to get you started beta testing the synth plugin. It also supports SFZ format out of the box!

* Register FREELY at edu.morningdewmedia.com/ and send me an email (from the same account) that you want in to the "Morningdew JORNA beta testing". I will attach the beta to your account and send you an confirmation email as soon as I've got the builds ready for download.

I think that's all. So sign up, send me an email and let's get the ball rolling!

**** Morningdew JORNA Beta begins tomorrow - Friday 2026-07-03 ****

Cheers, // Mattias
