Fixed a crash that could occur on mono audio output routes.

Refined MPE expression with mod wheel scaling, invertable axes, and smoother modulation. Mod Wheel Scaled Depth: Toggle inside each axis's Depth submenu — your mod wheel rides the MPE amount from zero to your set depth. Invert Y and Z: Flip the direction of a gesture without moving its rest point. Press harder to duck cutoff, raise Y to lower pitch, etc. Smoother MPE: Cutoff and pan modulation now ramp per sample, killing the audible stepping during fast playing or mod wheel sweeps. Better Pan Response: X to Pan and Y to Pan scale musically — small slides nudge, full gestures reach hard L/R. Y to XMod Fix: Pulling Y down no longer kills Cross Modulation in Center rest mode. Cleaner MPE Suffix: Shorter labels and a Y Rest arrow so routing fits in narrower popups. Pan Activity LEDs: Now blue, matching the envelope and audio indicators.

Fixed Export Preset producing zero-byte FXP files on iOS.
