Sir Sampleton is a sampling musical keyboard inspired by Casio and Yamaha samplers from the 80s.

New version 3.3.5
Old version 3.3.4
Release Notes There is an issue affecting a small number of users where the samples come out as loud noise. I've never been able to reproduce this issue on any of my devices or on any of Apple's iOS simulators, but I'm releasing an update built with the latest tools to see if it improves the issue. I suggest making sure you have the latest version of iOS installed and reboot your device completely. Also make sure you have microphone permission enabled for Sir Sampleton in settings. I've only received one or two emails on this issue over the last year, so I think it is only affecting a small percentage of users. If anyone is having this issue, please email me the exact device model and iOS version that you're using.

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

New version 1.0.1
Old version 1.0.0
Release Notes 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! 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!
