Hey everyone! You are Awesome and wonderful :) NOTE: iPhone 6/7/8 users with the view/sides cutoff – Do you have Zoom On in your iPhone? In your phone, try going to "Settings" > "Display & Brightness" and change zoom to "Standard". And, make sure Zoom is turned off in general accessibility. That will probably fix it for you. Good luck! :) + This update has small fixes + updates by volunteer contributors. + Synth One & all of these upgrades will always be free. Thank you!
You can help: Please tell your friends about Synth One. Together, we can change the world!
COMING TO AUDIOKIT SYNTH ONE: + AUv3 Plugin functionality + MPE support + More bug fixes and upgrades

1.0.1
Thanks everyone! Lots of NICE upgrades in this one: + NOTE: iPhone 6/7/8 users with the view/sides cutoff – Do you have Zoom On in your iPhone? In your phone, try going to "Settings" > "Display & Brightness" and change zoom to "Standard". And, make sure Zoom is turned off in general accessibility. That will probably fix it for you. Good luck! :)
UPDATES by Lord of Microtonality / AudioKit team-member Marcus Hobbs: • AudioKit TuneUp: The Tuning Panel now has a “back button” that will fast-switch back to the app that tuned up the synth without navigating to iOS. You can use apps such as "Wilsonic" to create tunings that will load into Synth One. Search for free app "Wilsonic" in the app store. This way, you can create scales & share micro-tunings between apps.
You have been asking for these updates for awhile, they're finally here: • The Sequencer Panel now has a beat “Divisions” knob that scales the arpeggiator/sequencer tempo from 1/64th triplets to 8 bars
• The Arpeggiator+Sequencer will now start when you press a key making it easy to perform with other instruments.
• The Envelopes Panel has a knob for ADSR Pitch Tracking. The higher the value the more quiet high notes become. This is useful for presets where the high notes are as loud or louder than bass notes.
• The Keyboard bar now has a Transpose stepper (semitones)
• Fixed bug in Hidden panel (HAQ Panel) where the “Freeze Delay, Freeze Reverb, Freeze Arp Rate/Seq Pattern” buttons weren’t working properly. Did you know Synth One has a secret hidden panel? See if you can find it ;)
Did you know the source code for Synth One is all online? And, you can contribute to the app! New contributor, Matt Siren, is a new volunteer who added something to Synth One this week: + He made the Delay smoother in this update Plus, he's got more things in the works. The AudioKit Source Code is available at https://github.com/AudioKit/AudioKitSynthOne/ Everyone is a volunteer. Feel free to jump in!
Other updates requested by users: + Home bar fades out when not tapped in the area on Devices without home buttons + Small fixes + updates
+ Synth One & all of these upgrades will always be free. Thank you!

+ Plus, we have released a fund-raising app called AudioKit Digital D1. 100% of the proceeds go to the AudioKit Project, and to support free apps like AudioKit Synth One for years to come. :)
MORE ABOUT THE NEW MICROTONALITY FEATURES: Each of these new hexany scales has "Just" intervals with several triads with one or more of the 3 pythagorean means: Harmonic (2ab/(a+b)), Geometric (sqrt(a*b)), and Arithmetic ((a+b)/2). It's easy to make music with these pure chords.
Based on the Erv Wilson 1997 paper "Proportional Triads in MOS" which constructed Recurrence Relations and "Moments of Symmetry" with the harmonic and arithmetic triads: I picked up where Erv left off by implementing his paper in code, adding the geometric mean, and searching through large odd and prime number fields for hexanies with these triads.
A Hexany is a polyhedra constructed based on the row of Pascal's Triangle which corresponds to a set of 4 numbers. The Hexany is "4 choose 2" (6 tones), the Tetrany (Major) is "4 choose 1" (4 tones), and the Tetrany (Minor) is "4 choose 3" (4 tones).
