Version 1.6 release notes

HEY EVERYONE! Thanks for being super awesome! NEW STUFF: + Do you have to pound your midi keyboard to get a note to play loudly? Do you barely press a key and have it play too loud? Well now you can adjust S1's sensitivity to MIDI Velocity in the Settings pop-over. Enable “Velocity-sensitive MIDI” and adjust the sensitivity knob to make your performance as expressive as possible for your keyboard. Also great with ROLI keyboards. + Fixed a bug that broke reordering your presets + Fixed a bug that hid the text of the name when saving presets. + Playing the Arp in down mode now plays keys in the order pressed (thanks to Francis Preve for this idea) + We are all volunteer musicians & coders. Thanks for your help! + Special thanks to volunteer coder Marcus Hobbs who added most of these features! Synth one is getting better every day! That's the power of open-source. Please note that we all are volunteers. AudioKit does not have any sponsors or investors. We are all musician/developers who love making apps. Together we can change the world. We love hearing your music! Send it to us.
