Jam Synth updates with more MIDI, and more

Here's what's new with Jam Synth:

• GREATLY IMPROVED MIDI OUTPUT: sends noteoffs, string bends work correctly (be sure to enable MIDI pitch bend in settings)
• portamento knob to adjust glide time between notes
• oscillators have more volume output
• volume mute and MIDI switch added to toolbar and as Audiobus triggers
• ADSR attack bugfix
• New IAP Intelligent Harmonizer: This creates musically correct harmonies based on the key you are playing in. The harmonies can be altered by choosing a specific interval and one of the seven musical modes: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian.
• New IAP Rotary Vibe: This recreates the swirling psychedelic sounds of the 1960's by combining a thick 12-stage stereo phaser with a 3D rotary panning effect. Create anything from a slow stereo swirl to a futuristic synth organ with this.
• iOS 7 bugfixes
