Release Notes Thanks Everyone! YOU'RE AMAZING! • Updates D1 for upcoming versions of iOS. Moving into the future with you! • Improves Sequencer functionality • We're working on everything you emailed us about. Stay tuned! Plus, other recent updates: • 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!
