## What is GlasSynth?

GlasSynth is a nine-operator FM synthesizer for iPhone and iPad, built around a resonator modeled on real glass. Strike it, move the microphone, and hear bells, keys and pads ring like crystal.

NINE OPERATORS, ANY ROUTING
• 9 operators, each with ratio, level, FM depth and its own DAHDSR envelope
• Sine, triangle, saw and square waveforms
• A 9×9 modulation matrix: any operator can modulate any other, or itself
• Drag to link, tap for classic stacked or parallel layouts

A REAL GLASS RESONATOR
• Resonance, strike position, microphone distance and microphone angle
• From a soft glow to shattered plate

STUDIO EFFECTS
• Chorus, delay, reverb (rooms, halls and plate) and a 3-band EQ
• Vintage mode for an older, warmer sound

MODULATE EVERYTHING
• 4 LFOs: sine, triangle, square, saw and sample & hold
• 16 modulation routes from LFOs, velocity, pitch bend, aftertouch, mod wheel and key tracking
• Poly, mono (with a detuned unison stack) and legato

68 HANDCRAFTED PRESETS
• Bass, keys, plucks, bells, leads, pads, strings, glass and FX
• Save your own sounds and step through them from the header
• Roll the dice for a whole new patch, or just one operator

PLAY IT YOUR WAY
• Standalone app with an on-screen keyboard
• AUv3 instrument plug-in for your favorite host
• MIDI controllers, virtual MIDI and MPE
• Keeps playing in the background

MAKE IT YOURS
• Four skins: Glass, Mono, Ember and High Contrast, with color-blind-safe accents
