What's New

NEW: Lower cost "Pro (Mobile Devices)" Subscription tier for Apple device owners who only want to use 'Pro' mode on iOS/iPadOS devices.
NEW: "Use Mix Properties Mix Rule" option in the Cell/Generator Rule Editors; select this to use whatever Mix Rule is selected in the Mix Rule Editor (accessed in Mix Properties).
IMPROVED: Rule Editors now display [Selected] and/or [Editing] next to the relevant Rule item in the list; this is to make it clearer which Rule is selected for composition and which Rule will be changed by modifications to top element editing panel.
IMPROVED: The Mix Rule Editor (accessed in Mix Properties) is where the desired Mix Rule is selected and it is identified with an append of "[Selected]"; in the Generator/Cell Rule Editors this Mix Rule is indicated by an append of "[Mix Rule]".
IMPROVED: The "Default" Mix Rule can now be deleted, cut and renamed; the exception is that the last Rule at Mix level (or Cell level) cannot be deleted or cut.
IMPROVED: In the Rule Editor the Action menu button is no longer shown for "Use Random Rule" items.
CHANGED: All included Templates that had a setting of "Mix: Default" have had this changed to "Use Mix Rule", this being a change to facilitate future engine extensions; when you change the selected Mix Rule the templates will work as expected.
FILE CHANGE: When opening a mix file saved prior to this update any "Mix: Default" references are changed automatically to "Use Mix Rule"; note that this is *not* done if the mix has more than one Mix level Rule defined (quite rare we think).
FIXED: Issue in 4 Column Display where column locks were incorrectly displayed in the Track Mixer panel.
FIXED: After a fresh installation Wotja will first open in "Documents > Flows".
FIXED: Title displayed in Mix-level Rule Editor (changed "Cell" > "Mix").

App Description

With just one tap of a button Wotja will create for you an awesome 'generative music' mix or play a live 'flow' of relaxing ambient music – and that's just for starters!

Free 'Lite' mode gives you 30 mins play time – plenty to explore how powerful Wotja is as a generative music system or to use it as an aid to sleep, meditation etc. No ads & no need to join a mail list.

Get Wotja to easily make, edit & play lush ambient mixes, epic drone scapes, text-to-music (TTM) melodies, beats & MIDI etc. for ideas, fun, relaxation etc. It’s a deep app that rewards curiosity.

"Nothing compares", "Masterpiece"

In 'Documents > Mixes' tap the 'Add New' button. Select 'Mix (Automatic)' from the pop-up menu.

In 'Documents > Flows' tap a Flow button.

Lots more! Explore composition, mix editing, sound design, randomization, scripting etc. [1].

Tap '? App Support' below and go to our 'Learn' section.

To do even more, take out a 'Pro' Subscription or get the Wotja Pro 21 app.

A 'Pro' Subscription unlocks 'Pro' mode, i.e. the Wotja 'Pro' Feature Set [1]. When this is active the app has the same functionality as the current paid-for version, Wotja Pro 21 [2].

SSEYO Koan (1990 – 2002), developed by us, generated what came to be known as 'Generative Music' (check out sseyo.com).

Wotja is the evolution of SSEYO Koan + ALL the other apps & tools we've lovingly crafted & pioneered over the years (Noatikl, Mixtikl, Liptikl & Tiklbox) - and it just keeps getting better & better!

We work hard to keep backwards compatibility - Wotja can still open & play SSEYO Koan content from ~30 years ago!
