Release Notes IMPROVED: 'Free Mode' - It took us a while, but we finally figured out how we could change it to allow *10 minutes* of mix editing play time (massively up from the previous 1 minute timeout!) and a full 10 mins of Flow/Album play time; the upshot is that many who use Free Mode may now no longer see a Timeout pop-up - Yay! IMPROVED: Implemented multitasking support for iOS / iPad (Split View / Slide Over); for Apple guidance on how to use multitasking see: https://support.apple.com/en-us/HT207582 IMPROVED: In TTM Cell, make the default action “Random Words” (was: Shuffle Words) IMPROVED: Added option to set Video Blob Colour to either None, Red, Green, Blue FIXED: The app could crash when previewing an item and adding it to a cell FIXED: More bugs and improved stability P.S.

JAX Stereo Tool is a visual Audio Unit plugin for manipulating the stereo image of digital audio.

New version 2.3
Old version 2.2
Release Notes 2.3 (third maintenance update) IMPORTANT: the type of the audio unit has been changed to provide MIDI support ('aumf'). existing projects possibly must be updated to access the new AU type. A: ui improvements - the user interface was completely reworked to provide much better contrast adjustment and readability and to fix some glitches with zooming and moving. the main controls now additionally give visual feedback, if tapped. B: the contrast overlay controls can be hidden/revoked by a one finger long press gesture - sometimes the ui moved around while adjusting the contrast with the slider. we fixed this. C: AUM parameters - the parameters are now specially exposed to the the AUM host app. the publishing of the main parameter (stereo width) disappeared therefore, because of the AUM MIDI type menu. D: MIDI parameters - the type of the audio unit was changed to support MIDI automation directly. the parameters stereo width, panorama and also volume can be automated with the standard continuous MIDI controllers 11, 10 and 7 now. The distribution app therefore got some new buttons to establish MIDI connectivity. E: parameter interpolation - users possibly want to dynamically automate volume, stereo width and panorama. so we implemented parameter smoothing for these realtime parameters to prevent zipper noise with automation. Especially MIDI automation requires parameter ramping, because MIDI values are usually quantized to merely 128 raw values per controller. - note: some parameters (sample offset and all switches) are not thought for realtime automation and still may produce clicks or zipper noise when tweaked. this lies in nature of things and would require too much effort and advanced techniques to fade between states, which is not the purpose of this audio unit. F: new bezier mode - the correlograph can be toggled between points cloud and bezier mode. the bezier mode requires much more performance. so it is tagged as "experimental". while latest Apple devices should have enough power to run it, some older devices probably will make the UI stuck, while it is on. it was not even easy to get the points cloud to perform acceptably. - if you do not use the graphs permanently, we recommend to switch it off, as this significantly improves entire graphics performance and reduces CPU usage. G: the phase shift display was fixed to reflect the correct sample offset count and corresponding milliseconds value dependent of the current active samplerate. H: the graph is now always proportionally resized with the plugins interface. the previous sizing was independent of the main ui, confusing some users.

Old version 1.0.72
Release Notes UX changes, also verified that Midi CC works in Standalone and in AUM. The knobs do not update with the midi changes visually, but do audibly. That is a TODO. You can test by setting a Midi CC on Algorithm in the lower third of the synth. The algorithm plot window will change, but the knob won’t. Midi CC is more error-controlled now. Midi CC ON now locks scrolling and locks parameters and is meant for a single run. So if you want to map an other value, you will have to turn it on again. Past updates: Zooming has been removed temporarily so you don't have to suffer with an unstable release until it's working. Please let me know of any errors as I now have a STABLE and DEVELOPMENT branch. Panning/scrolling is done with two touches now. LOCK PARAMs and LOCK SCROLL also now work again. You can scroll the CART .syx file browser with one touch, but may need to pan with two touches to the top of the CARTs file viewer. Knobs and sliders move with one touch. If you didn't get the master collection of 640,000+ patches, delete the app off the home screen and download from the App Store again. Knobs and sliders move with one touch. If you missed out on some previous versions there is a loading screen that should not be force quitted.
