What's new in v1.0.7.2

THANKS EVERYONE! Here's even more bug fixes! We <3 you.
+ Poly/Mono mode works correctly!
+ Transpose above keyboard is saved with each preset!

Plus everything in 1.0.7 - We're always improving Synth One!
This update fixes the top two types of crashes people have with Synth One. Thanks to volunteer Matthias Frick for these fixes.
Plus, NEW code by Marcus Hobbs:
• Single Tap Display Control Value: single tap of a control displays it’s value in header…no more changing controls to see what their value is
• LFO smoothing: Saw & Square wave LFO’s now are smoothed to reduce/eliminate clicks and pops
• Taper: Master Volume and Filter Cutoff knob have values more evenly spread (does not affect presets…just how the controls make the most of their range when dialing in sounds)

• Fixed new sound bank "Sound of Izrael 2" (SOI)
• New App Store Preview Movie for iPhone featuring music made with Synth One by Brice Beasley

Synth one is getting better every day! That's the power of open-source.
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!
