This application is simply a container for the Audio Unit and also serves as the documentation for the AU. PhaseDelayArray is a bit of a strange effect. O.K, so, what is it? PhaseDelayArray has three effect units chained together in an interesting configuration, and one of these units is just a little bit twisted.

Wotja X is a new cross-platform interface for the 'Wotja Generative Music System'.

New version 20.12.7
Old version 20.12.6
Release Notes This is the final Wotja V20 update and it includes minor bug fixes. The next update will be on Jan 1st and it will be Wotja V21.0. This will require iOS 12+ (iOS 13+ for TTS support). *IMPORTANT FOR "PRO" SUBSCRIBERS*: Back in May 2020 the "Pro" Feature Set (FS) Subscription went "dual" - meaning one Subscription worked in both iOS and macOS versions. At the same time we also gave a heads up that from January 1st 2021 onwards we would be increasing all existing "Pro" Subscriptions. The "Pro" Subscription is now $2.49/month (and has been for a while) and represents great value. Should you be an early "Pro" Subscriber on lower price we hope you choose to continue your "Pro" Subscription with Wotja V21. For those that would prefer instead to convert to a paid-for app you may be interested in our end-of-year sale on "Wotja Pro 20" for iOS. We are running this sale price until 31st December when the app will be removed from sale.  You might also be interested in checking out "Wotja Pro 21" which is to be released January 1st 2021. We *hope* we can make it available to pre-order before then but we are working to a very tight schedule. Wotja Pro 21 is a single purchase (i.e. one single price) for use on both iOS and macOS meaning you could pre-order the macOS version and know you will get the iOS version when it is available! See also this FAQ entry: https://intermorphic.com/help/#faq-wotja-pricing As ever, if anything is not working right then please do get in touch via our Help Page ‘Contact Us’ options. P.S. Enjoying Wotja? Please do leave or update a positive review and rating - your love means so much to us! Thank you :).
