Eight-voice polyphony with detune-and-spread unison, audio-rate filter envelope, classic SID-flavoured ring modulation and pulse-width modulation, plus a built-in 4 to 64-step sequencer and tape-style delay, chorus, distortion, and lush reverb. Wrapped in a neon Liquid-Glass interface that matches what's playing — magenta sequencer steps that bloom lime when active, a gradient cyan oscilloscope that traces your output in real time, and a synthwave horizon that rolls under the step grid. FOUR TABS SYNTH — oscillator (triangle, sawtooth, square, noise) with PolyBLEP anti-aliasing. Custom Cytomic state-variable filter (low-pass, high-pass, band-pass, notch) with drive and self-oscillating resonance. Audio-rate filter envelope. LFO with pitch, cutoff, PWM, and pan destinations. Ring modulation. Distortion (lo-fi, broken, cubed, bitcrush, mangled). Chorus. Delay. Reverb (plate, room, hall, cathedral). Big rotary knobs, all the modulation routing visible. SEQUENCER — 4 to 64 steps. Tap-to-place notes with the chromatic note picker. Per-step ratchets (1x, 2x, 3x) and held-legato notes for gate-length variation. Tempo from 60 to 440 BPM, gate length 5 to 150 percent of step. KEYBOARD — two-octave touch piano with multi-touch chords and slide-to-play, velocity slider, octave switcher (C2 to C6). RECORD — capture everything you hear (filter, drive, delay, reverb, the full chain) to a WAV file in the app's Documents folder, then share via the iOS share sheet. 5 to 60 seconds per take. LuSID is built for the moments when you want to make sound, not learn software. No menus, no preset hunting, no tutorials. Tap a step, sweep a knob, hold a key. The app treats every parameter as performance. NO ACCOUNTS. NO ANALYTICS. NO TRACKING. NO ADS. LuSID does not collect any data, make any network requests, or contain any third-party SDKs. Recordings stay on your device until you choose to share them. ## LuSID Synthesizer Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/46/a5/2b/46a52bbd-f784-7f5f-a43a-9ebb3ef33c46/01-synth-default.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/60/46/fd/6046fd65-efee-804d-6b76-001d09f689b0/02-sequencer.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/33/79/77/3379770f-2df0-f4cb-87d6-e1a60784a254/03-keyboard.png/1320x2868.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/3c/32/62/3c326291-fff2-8762-5686-6ba39151a9f3/04-record.png/1320x2868.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/3a/bb/0d/3abb0d37-daf4-1801-8f74-d522311a0b57/01-synth.png/1320x2868.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/78/57/f1/7857f1aa-3cf3-7313-c93b-19b528860ff0/02-sequencer.png/1320x2868.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/0d/14/b3/0d14b309-3719-ae80-2e68-79ab3f3d693b/03-keyboard.png/1320x2868.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/5f/7f/91/5f7f91d4-4b85-d752-6e78-0fbd536b4f77/04-record.png/1320x2868.png) ## LuSID Synthesizer Rating Breakdown in United States - 5 stars: 1 (100%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 0 (0%) ## Apps Similar to LuSID Synthesizer - [Jaw Harp Synth](https://apptail.io/app/jaw-harp-synth-aVwy/united-states) - [Stylloop - Pocket Synthesizer](https://apptail.io/app/stylloop-pocket-synthesizer-yCSy/united-states) - [Touchophone - Synthesizer](https://apptail.io/app/touchophone-synthesizer-llWy/united-states) - [3D Synth](https://apptail.io/app/3d-synth-Volz/united-states) - [MIDI Controller/Oscilloscope](https://apptail.io/app/midi-controlleroscilloscope-DHyz/united-states) - [Pentaholic Synth](https://apptail.io/app/pentaholic-synth-IKEz/united-states) - [S-2](https://apptail.io/app/s-2-PlMz/united-states) - [ToneNoise](https://apptail.io/app/tonenoise-MiNz/united-states) - [MGP-2 Makk Guitar Processor](https://apptail.io/app/mgp-2-makk-guitar-processor-uPSz/united-states) - [Synesthesia Synth](https://apptail.io/app/synesthesia-synth-iBVz/united-states) ## LuSID Synthesizer Available In - [United States](https://apptail.io/app/lusid-synthesizer-YGHz/united-states) - [Bahrain](https://apptail.io/app/lusid-synthesizer-YGHz/bahrain) - [Brunei](https://apptail.io/app/lusid-synthesizer-YGHz/brunei) - [Canada](https://apptail.io/app/lusid-synthesizer-YGHz/canada) - [Colombia](https://apptail.io/app/lusid-synthesizer-YGHz/colombia) - [Czechia](https://apptail.io/app/lusid-synthesizer-YGHz/czechia) - [France](https://apptail.io/app/lusid-synthesizer-YGHz/france) - [Ghana](https://apptail.io/app/lusid-synthesizer-YGHz/ghana) - [Croatia](https://apptail.io/app/lusid-synthesizer-YGHz/croatia) - [Sri Lanka](https://apptail.io/app/lusid-synthesizer-YGHz/sri-lanka) - [Türkiye](https://apptail.io/app/lusid-synthesizer-YGHz/turkey) - [Azerbaijan](https://apptail.io/app/lusid-synthesizer-YGHz/azerbaijan) - [South Africa](https://apptail.io/app/lusid-synthesizer-YGHz/south-africa) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
