What’s New

Version 23.1.0

NEW: W23 'Pro' (Mobile) Unlock IAP option in the Wotja In-App Store for those wishing to use Wotja 23 on _iOS/iPadOS only_.
FIXED: 'Listening' generators now work again in the AU3 Plug-in.
FIXED: When the AU3 Plug-in window was open and a new document was created (e.g. Mix), it could look like the AU3 Plug-in has hung; it hadn't, but the alert asking for a document name was behind the AU3 Plug-in window.
FIXED: If an underlying Template used by a Cell had gone missing that Cell was blank, even if there was custom data in that Cell.
FIXED: Sped-up the macOS TTS speech rate (macOS 13+ required) to match that in iOS.
FIXED: Display of file sizes in Mix Record tab.
FIXED: Rare crash using RHS menu button in Documents list.
FIXED: Rare crash on App shutdown.
FIXED: Rare crash on AU3 Plug-in shutdown.
FIXED: Rare crash where Scale rule index could go out of range in the composition engine.
FIXED: Some _very_ old content could have an invalid filter type in the FX network data, resulting in a Filter that had no effect; it is now treated as a standard Low Pass.
FIXED: Parsing of (very) old format Noatikl file data (V1 Noatikl XML format).
IMPROVED: We now use a standard macOS single-line text entry alert where possible.
IMPROVED: We no longer append the date/time to recording file names.
IMPROVED: Updated Wotja file icon in Documents screens.
IMPROVED: Updated User Guide.
OTHER: Various other minor fixes/improvements.
MORE: See W23 Releases on website.

First of all, the developer(s) are amazingly responsive, helpful, patient, kind, and enthusiastic. Communication is a pleasure. I've used the predecessor of this unique app in the past (Liptiki) and loved it. I've also briefly checked out Wotja last year. Sadly, I was overseas and blew up my MacBook. For the past several months I missed playing with this software! Wotja is a totally different format, so it might take a couple launches for the workflow to sink-in. It's not a DAW (digital audio workstation). It's an otherworldly environment that helps inspired creativity . . . especialy within it's melodic ambient wheelhouse. Of course, users are not trapped on this new planet. We are able to use Wotja as a sketchpad and then continue developing in a DAW, if one so desires. At the very, very least . . . this app breaks through creative blockage and is FUN to use after climbing over a little learning curve. For the price . . . FREE . . . you can't beat this. I've got my eyes on the paid version for the enhanced features. Tommy Zai gives this two thumbs up.

Wotja can be as simple as a visual and auditory experience that mixes written words and generative music. Wotja includes many pre-generated mixes and makes it easy for you to create random mixes with just a a couple touches.

Wotja can also be a very deep modular environment where you can edit every aspect of your music and sound parameters. The music engine is very adaptive with rules and settings that you can set for how each part plays. The sound engine is where you get your hands dirty building and editing your modular “synth” creations using sound/tone sources, FX units, controllers and routing junctions.

I don’t think I’ll ever get to explore all of Wotja’s features, but I do learn new things every day with the help of Intermorphic. Anytime I hit a wall, it gets knocked down pretty quick with explanations for those little things that aren’t readily apparent to me.

If you are brave enough to take the dive into Wotja’s vast generative and modular music environment, understand that you have a vast amount of control and there is probably a setting that you can tweak to make your creation sound just the way you want.

Thank you so much for your wonderfully detailed review and we greatly appreciate you taking the time to leave it. We hope you continue to enjoy Wotja as we further evolve it and its capabilities!

Superb package for ambient music creation

Wotja a complete package for the creation of ambient, generative music. Offering complete and comprehensive control of all parameters, it makes possible gorgeous, ambient music. As someone who has been creating this kind of music for a while, Wotja enables me to achieve my vision in ways no other software can. The monthly subscription model is a total steal; if you need support, it’s fast, technically sophisticated, and patient. The latter is important as I think I have asked every dumb question I can about the software. The support people are unfailingly friendly and very helpful. If you have the ambient gene, this package is for you,

Developer Response ,

Thank you so much for your kind words - they really do mean a lot to us! Glad we were able to help, too. We hope you enjoy Wotja as we continue to develop it. With best wishes, Tim
