Just Intonation android app: F above C3 will depress but won't produce sound
Every note in the two octave range from C2 to C4 will produce sound when depressed, except for the F above C3.
I'm on a fresh install of v1.3.0 downloaded via Google Play to my Nexus 5 Android 6.0.1 stock rom.
I'm using Artificial sound. Bug occurs regardless of whether Just Intonation and Compensate Pitch Drift are enabled.
