Release Notes Thanks Everyone! YOU'RE AWESOME – MORE UPDATES FOR YOU! • AUv3 now mixes down and freezes in Cubasis, NS2, GarageBand, and more! Plus, 1.4 Updates Include: • D1 has been re-engineered to allow AUv3 in iPadOS/iOS 13 This is still a new feature, we are working to improve it! • Inter-app Audio (IAA) has been improved! • Misc bug fixes & upgrades • AudioKit apps will keep improving. We're working hard to make them better for you! NOTES * D1 is rather robust. It's a beast of a synth. * We've re-engineered and optimized it so you can run 2, 3 or more instances in one project! Of course, if you go above 3 instances running at once, it may become unstable. * AUv3 also handles MIDI better. Use your favorite iOS host like AUM to route MIDI to different instances * AUv3 mode defaults to CPU efficient mode on, which means you don't see the knob animation on LFOs. BTW, this makes it easier to set LFO targets. This can be changed in the "Settings" button to the upper left of the keyboard * There's a new keyboard hide/show icon that appears at the top of the AUv3 mode to make it easier to show/hide bottom panels in AUv3 mode * We can't wait to hear the music you make with D1 as an AUv3 * The app will just get better & better - stay tuned! Email bugs, music, & friendly notes to: hello@audiokitpro.com We're working hard to improve the app for you! Stay tuned!

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.

Release Notes 1.4. (fourth maintenance update) A. moveable modal boxes we have made the 'modal boxes' for the modulator, oscillator and saturator modules moveable now. the boxes will be ready to be moved freely inside the plugins effective area, if no internal control is hit. the positions are remembered for the current session only, as it would create problems while loading with different host apps due to different window sizes and handling. there can only be one modal box opened at same time for certain reasons, but the positions are individually remembered for each type of dialog while working with the plugin. the global zoom feature affects everything, not merely individual boxes. The move feature can be globally locked with the freeze button. the freeze button will be invoked or hidden by a long press gesture. to close a box, one must tap outside the visible area of the box. the double tap with 2 fingers will reset everything to default positions. B. zooming behavior the model selector (exposed via [ menu ] button) will not disappear anymore by tapping outside, to support zooming while it is open. The menu button must be tapped explicitly to close the menu. if you want to zoom into open modal boxes, you must ensure to pinch inside their areas to make not disappear these automatically. a tap outside will automatically hide any open modal box. this was a requested user feature and we won't change that again. C. improved contrast behavior modal boxes now also support the contrast feature with their own semi-transparent background. we also improved the entire contrast to get really more visual difference. it is done by just inverting the main color in relation to the background color. this should optimize usage with extreme lighting and give entirely more contrast. this also affects all the main labels. D: labels made bigger all the labels of the user interface were made 1 point larger for better readability. this is maximum as it already looks quite clumsy now. ^^ E: removed Bluetooth MIDI connectivity We decided to remove MIDI connectivity features from our releases completely. the reason is, that we always have to provide videos for the app store staff with each update release to demonstrate this iOS system feature with our distribution apps. we have not the time to endlessly capture videos of basic iOS system features, as these system functions are merely invoked by the app, not coded. it is not our code, nor do we even have influence to these mechanisms, so we do not see the logic in the demands of the app store review staff, notoriously asking for demonstrating sub features of our apps, that are in fact features of the OS. So Bluetooth MIDI cannot be established any longer with our distribution apps. it is also not a requirement for the operation of the audio units, b.t.w. F. audio improvements and extension delayed again some audio issues (like hot signals, loudness adjusting, additional comb effects) will come with the next update, as far there is even any interest for that.

Make Louder is not based on complex dynamics processors and it is also not an overdrive or amplification or saturation effect. We created a special digital algorithm that can boost audio in loudness up to a certain limit, without colorizing the sound too much. And it can prevent the audio to exceed the output limits if you for instance stack together many sound sources.

Release Notes 2.0 (first major update) A. initialization issue fixed there was an initialization issue with GarageBand, not showing the correct initial values. GarageBand obviously is a host app, that automatically assigns the first preset of the included preset list on initialization. however this was not intended to be used that way. so we fixed it by initializing all presets to default values. B. dummy parameter removed there was a testing parameter "Parameter1" left, which is removed now, as it does nothing. C. pumping reduced there was an audible pumping with high gain levels audible. we adjusted the internal limiter model to get shorter release times. please note, that very short speed parameters may introduce audible transient clipping. D. limiter speed parameters simplicity sometimes is not good enough for advanced users. so we exposed new parameters to adjust the limiters speed. the amount ranges from 0.01 to 1.0 seconds, default value is short (0.2 seconds). there are 2 values available, because there are 2 independent limiters active when using 'double boost' switch. these 2 limiters can have completely independent speed parameters, which produces a variety of adjustments. the limiter speed can be seen as a kind of 'release time'. shorter values reduce pumping but tend to produce transient distortions. you must find a good balance depending on the input audio source material used. Larger values provide a sort of AGC (automatic gain control) functionality. E. major UI & parameter update the user interface was resized and extended to get 2 new main processors with corresponding controls. there are 2 brand new tube amplifier models integrated now, which can boost loudness effectively, but this time, with 'colorizing' the sound. the "red tube" is an aggressive tube amplifier model with strong tendency to soft overdrive and soft distortion. the green tube amplifier is a more decent tube model with a much softer saturation effect, it is quite comparable with a tape saturation type effect. we recommend to use these tube amplifiers with some care, as these do add strong harmonics to the sound. probably this is exactly what you are looking for with some audio material. the tubes output is always fix-connected to the brick-wall limiters. switching the limiters off will result in passing the original signal thru. advice: we highly recommend to use automation with all of our plugins, as static parameters usually never work perfectly for all parts of an audio stream. F. ui freeze option added the user interface can be frozen now (pinch2zoom&move), to not accidentally move it around while tweaking the controls. the freeze button is integrated into the controls overlay, which can be hidden/shown by a long press gesture. G. contrast adjustments we improved the contrast adjustment of the user interface. the main color will be inverted in relation to the background to provide even extreme contrast with much better readability.
