Developed by us, SSEYO Koan (1990 – 2002) generated what came to be known as 'Generative Music'.
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!

Version 21.9.1 release notes
IMPROVED: Documents view simplified to now be just 3 main screens, 'Flows', 'Mixes' and 'Albums' (we think we have now finally nailed this!).
IMPROVED: 'Show' button added to each of the 3 Documents screen to allow (relevant) filtering of which files to display or hide; button in Mixes screen also includes Name search option ('Pro' mode only).
IMPROVED: Document sorting options have been moved from the 'Actions' menu to a 'Sort' button added to the 'Mixes' and 'Albums' screens.
IMPROVED: 'Generator Type' moved to be above Generator Name.
IMPROVED: 'Cell Gen Bars/Repeats' moved to above Cell Rules.
IMPROVED: Some 'Standard Rule Values' Rules renamed and moved to the top of the Rules list to make them easier to find (these Rules values help with understanding of how Rules work together).
IMPROVED: Flow Player > Action > 'Save Flow to Wotja Mix File' moved to be the first item making it easier to find.
