Minor internal fix

Slightly tweaked the Wavefolder effect to avoid excessive loudness peaks across the range.

What's new in this Mononoke update:
- Dynamic Saw oscillator in the voice section (which can blend in and out with its own LFO)
- Sample&Hold LFO type for rhythmically randomizing your oscillator effects
- Wavefolder between the Mood and Ambiance effect units

Lots of little improvements in this update:
- You can now tune the knobs to a selected scale automatically
- Selected notes are now displayed inside the tuning knobs
- UI optimizations for use on phones

Now also includes an extra MIDI AUv3 plugin: "Mononoke Pads", which lets you play other MPE synths using Mononoke's performance pads. Have fun!

- MPE Pitch Bend range is now +/- 24 semitones... bend away!
- Optimized MOOD effect
- Changed default settings when starting the app
- Display of free tuning is now correct in the LCD
- Disabled legacy MIDI CC control on channel 1*

* it is recommended to automate synth settings using AU Parameters. In case you want to change settings using the legacy CC method, make sure you send these controls on channels 2-16. This is to keep channel 1 free for hardware MIDI/MPE controllers while still being able to map knobs to AU Parameters; and to avoid that Mononoke receives parameter changes twice: via AU Parameters and via direct MIDI input.

Thanks for your overwhelming enthusiasm and support for Mononoke!

In this quick first update I've fixed some small bugs and added some tiny features:
- when tapping the tuning knobs you now see their current tuning setting before changing them
- the LCD tuning display was off (yeah, that one was silly)
- fixed an AU parameter scaling bug
- fixed a possible issue when triggering notes in the negative octave range (notably D-1) in MIDI mode
