What's new in v1.0.4

Thank you for using AudioKit Synth One. This is a free project, made possible by you! :)
+ Synth One now loads 400% faster! Synth One starts lightning fast now.
Thanks to Matthias Frick from Ableton for this feature. Plus, other great contributions in this update:
+ Fixed a crash that would occur when headphones are being plugged in on some iOS devices
+ Improved how allocation/deallocation of the DSP Kernel is being handled
+ Fixed a small memory leak with portamento-voicing
+ Removed use of malloc in C++ code
+ Bumped C++11 to C++17

Updates by Matthew Fecher:
+ Now saves MIDI Learn on 20+ more knobs - Will now load/save "MIDI learn" settings on ADSR & FX Panel knobs
+ Fixed "save as" functionality. If you rename a preset it will create a copy, instead of saving over the original preset.
+ Synth One & all of these upgrades will always be free. Thank you!

+ 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.
