Release Notes MAJOR NEW FEATURES • Finally, updated to Ableton Link 3 with start/stop support! • Add new "MIDI strip" channel type to hold MIDI-only AU plugins. • Allow importing channels from another session. (Tap IMPORT add-button, or long-press a session file and choose 'Import channels') • Allow easy duplication of channel strip. • Allow loading sessions via MIDI actions. Its configuration is saved globally instead of in the session. • Add MIDI program change as recognized MIDI control messages. • Add MIDI ctrl for tap tempo. • Add MIDI action 'Show Plugin' for AUv3 nodes. • Add MIDI actions for AUv3 preset-loading. • Avoid stuck notes when bypassing/disconnecting MIDI sources or changing MIDI destination filter/transpose • Show AU contextName (if set) in plugin title and as node icon subtitle, long-press AU plugin title bar to edit. IMPROVEMENTS • Re-apply preferred samplerate on audio interface route change. • Remember preferred sample rate on app launch. • Save preferred instead of current sample rate in session. • Bring keyboard to front if currently behind the plugin window when tapping plugin window keyboard button. • Send error string to Audiobus if preset load failed. • MIDI matrix: highlight source and dest on touch-down. • Support upside-down portrait on iPhone. • Improve display of long names in MIDI control table. • MIDI learn consistency: always ignore the message that triggered the learn. • Tweak node param-knob and menu button layout for consistency. • Only update latency compensation on node-bypass if the node has latency. • Save project: save when tapping Return on keyboard. • Various minor UI and layout tweaks. • Keep connections to MIDI Control from permanent MIDI sources on load/new session. • Minor optimizations for MIDI Control. BUGFIXES • AUv3 Transpose: ignore extra bytes in note messages (hello Thesys). • Clear MIDI matrix when loading session so it isn't keeping connections from previous session. • Don't crash when trying to MIDI-control parameters of a crashed AU plugin. • NodePicker: avoid keyboard on iPhone. • NodePicker: fix memory leak if dismissed while in search mode. • NodePicker: hide 'remove slot' button while searching. • NodePicker: hide search if collection empty. • Make sure we don't free MIDI sources/destinations too early. Hopefully avoids rare crash... • Improve MIDI safety when AU plugin was invalidated (crashed). • Update MIDI matrix correctly if visible while loading session.

AudioKit Synth One is a completely free & open-source professional iOS Synthesizer. 

New version 1.0.5.1
Old version 1.0.5
Release Notes Thanks everyone! Quick fix to help some MIDI controllers work better with Synth One. Fix by musician Matt Sieren in Berlin. Check out his music at soundcloud.com/sieren That's the power of open-source. Anyone can add to AudioKit Synth One. It's a worldwide effort of volunteers! :) PATCH SHARING: Upload your favorite patches for the world to check out: https://patchstorage.com/platform/audiokit-synth-one/ Big thanks to Byran Hillebrandt & PatchStorage for creating it! ---- Additionally, Synth One founder Matthew Fecher has written something. Why we made Synth One: Music is everywhere. It’s one of the things we love about living in this world (along with coffee, guacamole, and a few other things). Think about how music has changed. I’m not talking about how Nirvana changed music in the 90s. I’m not even talking about how The Beatles changed music in the 60s. Go further. What about Bach? What about Ugg? Wait, who’s Ugg? Ugg is the cave person I made up. He banged a rock with a stick, did the first drum stick twirl, and gave a cool “Ooooooooh.” My point, which probably took too long to make, is that we’ve come a long way since primitive musical instruments. What would Bach or The Beatles have done without pianos and guitars? They might have cured cancer or something, who knows, but they gave us incredible music. They had access to the instruments of their time. And, they changed lives through music. Now think about the countless people who could have created amazing pieces if they’d had access to instruments. Think about all their lost music. What could they have created? That’s what inspired us to create AudioKit Synth One. There are millions of people around the world with access to iPads through school or social programs. People who have the next wave of life-changing music in them. But many can’t afford professional apps and even more don’t have credit cards to download them. The idea that someone who might have been lost to music history will now have access to amazing tools to create music is what inspires us. It inspires us when we have a bad day. It inspires us when we struggle with code that won’t run quite right. Synth One is limited only by your imagination. People are using it for radio, television, PODcasts, YouTube, films, video game production, commercials, and more. The world needs your music. We’re not saying we are going to create world peace… but we’re not NOT saying that either. Free, open-source tools like Synth One inspire musical creativity and can be amazingly powerful in anyone’s hands. Tell a musician you care about. Together we can change the world. Go. Create. Share. -- Matthew & the AudioKit Team COMING TO AUDIOKIT SYNTH ONE: + AUv3 Plugin functionality + MIDI Clock sync support + MPE support + More bug fixes and upgrades Please note that we all are volunteers. AudioKit does not have any sponsors or investors. We are all musician/developers who love making apps. Any help spreading the word about this app would be appreciated. The more people that know about the apps, the more musicians can enjoy them! Thank you! We love hearing your music! Send it to us.
