Version updates

This is a very simple yet powerful iOS app that performs as a polyphonic audio synthesizer.

New version 2.16.0
Old version 2.15.1
Release Notes Added two new AUv3 effects to replicate those found in the main app. These can be used with any other AUv3 instrument, not just the SoundFonts instrument. • Delay -- repeats the input signal. Contains a UI with knobs for the time of the delay, the amount of output audio to feedback into the delay, a low-pass frequency cutoff, and finally a mixer control to determine how much of the original signal and the delayed signal are present in the output. • Reverb -- processes the input signal to sound like it is being played in a room or large open space. The UI controls the room preset and the mix of original and reverberated effect in the output.
