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 GlasSynth collects no data.
