Build animated electronic instruments from four synthesis engines. Blend Subtractive, FM, Karplus-Strong, and Wavetable layers. Sentium Glitch is a stereo AUv3 synthesizer for producers, composers, and sound designers who want layered motion inside one focused instrument. Use it in compatible AUv3 instrument hosts, or open the standalone app on iPhone, iPad, Mac, and Apple Vision Pro to load the same experience, connect MIDI inputs, and play it as a standalone instrument. Every patch is a complete sound design document: four engine layers, per-layer envelopes, filters, LFOs, modulation routes, pan, level, engine bypass, master effects, polyphony budgeting, voice mode and glide, and optional recorded XY Pad motion all recallable through presets and AU host project state. Core sound engines: - Subtractive: dual oscillators, sub, noise, detune, pulse-width shaping, and multimode filtering for classic analog weight and layered fundamentals. - FM: five operator topologies for bells, keys, metallic basses, and aggressive digital color: two-operator, blended two-operator, stacked, dual-modulator, and split-carrier. - Karplus-Strong: plucked and struck delay-line resonators for guitars, kotos, mallets, metallic attacks, and hybrid acoustic-electric textures. - Wavetable: curated morphing tables with vocal formants, digital edges, harmonic motion, seeded-random spectra, and unison width for animated modern tones. Performance and modulation: - Poly, mono, and legato voice modes with adjustable glide (portamento) for tight monophonic basses and expressive, gliding leads. - Two XY pads with four routable axes. - Record XY pad motion per engine and save it with the patch. - Route LFOs, envelopes, velocity, aftertouch, pitch bend, mod wheel, CC74, and XY pad axes to musical targets. - Move oscillator pitch and mix, FM index and ratios, Karplus brightness and decay, wavetable position and detune, filter, pan, gain, LFO rates, and master-FX controls. - Sync LFOs, chorus rate, and delay time to host tempo when available. Patch and mix tools: - Four-layer engine mixer for balancing, panning, and bypassing each sound source. - Master chorus, delay, reverb, level, and soft clip. - Global polyphony budget up to 32 voices with device-aware runtime limits. - Stereo output at 44.1, 48, and 96 kHz sample rates where supported. - On-screen keyboard with pitch and modulation wheels, plus CoreMIDI input management in the standalone app. Factory and user library: Start from 92 factory presets spanning signature motion patches, classic synth tones, basses, leads, keys, bells, plucks, strings, pads, rhythmic textures, atmospheres, experimental sounds, and technical references. Save your own user presets locally with iCloud sync when available. Export selected saved user presets as .sgpresets files and import them through a preview workflow that appends new user presets without overwriting the existing library. Sentium Glitch is built for sounds that move: evolving pads, unstable digital bells, hybrid plucks, animated basses, cinematic sweeps, mono leads that glide between notes, and expressive performance patches that respond to your hands.

SL Tymra combines sampled instruments and synthesis in a two-layer keyboard instrument. The included library has 448 sounds in 15 categories, including pianos, organs, basses, leads, pads, strings, winds, mallets, plucks and textures. Set the source, octave and level of each layer, then blend them. Adjust attack, release, cutoff and resonance. Add chorus, delay and reverb. Mono and Legato support connected lead and bass lines. Glide controls the pitch transition between notes, from 0 to 500 ms. Browse by name or category, mark favourites and save edited sounds. AI Match searches the included bank locally using the sound character you select. It works offline. Play the on-screen keyboard or connect MIDI. Use Tymra on its own or as an AUv3 instrument in a compatible host. iPhone and iPad support portrait and landscape layouts. The library is included. No subscription, additional sound-pack purchase or account is required. The Mac edition is sold separately.
