ByteBeat vs LuSID Synthesizer

Draw a shape. Hear it as music. Or describe a sound and let AI help you write the code. ByteBeat is a creative coding playground where sound comes from code — techno, chiptune, glitches, drones, and unexpected textures. Start with a drawing, explore a ready-made track, or write one line of math and press play. DRAW IT, HEAR IT, EXPLORE THE CODE Draw a line in Sound Canvas and it becomes a loop — left to right is time, up is higher. Add layers for harmony, bass and drums, or tap Make It a Track to build an arrangement around your shape. Pick a mood and experiment. Open the code behind your drawing to explore how it works and make it your own. DESCRIBE YOUR NEXT SOUND Meet the ByteBeat AI assistant. Ask for a rhythmic chiptune, a darker bassline, or a slower groove. Generate a new formula or ask for changes to your current code. The result goes straight into the editor. Review it, press Apply to hear it, and keep experimenting. Undo or revert when you want to go back. START FROM REAL TRACKS Explore built-in presets ranging from classic one-line formulas to layered arrangements in techno, house, trance, synthwave, drum and bass, cinematic, lo-fi electronic, and ambient styles. Every preset opens in the editor, so you can read how it works and rewrite it. A REAL CODE EDITOR Syntax highlighting, line numbers, undo and redo, and a one-tap row for common operators. When something breaks, error messages point to the line and column so you can find your way forward. LEARN AS YOU GO Start with a guided tour, explore a guide to the app’s controls, or open the language reference from the editor. Runnable examples introduce the operators, rhythms, melodies, and synthesis techniques behind your sound. SEE YOUR SOUND Watch an audio-reactive visualizer respond to your music. Switch skins and scenes, or enter full-screen mode to put the visuals first. SAVE, EXPORT AND SHARE Keep your formulas and canvases in a personal library. Sign in to back up and sync your saved code presets. Export WAV audio, create videos sized for TikTok or Instagram, or share a link that opens your formula in ByteBeat. UNDER THE HOOD • Classic and JS-big evaluation modes • Bytebeat, signed bytebeat, and floatbeat output • Six sample rates from 8 kHz to 44.1 kHz • Adjustable audio buffer size • Editable formulas and layered sound experiments Start drawing, coding, and playing offline without an account. AI assistance and cloud sync require sign-in and an internet connection. WAV exports longer than 15 seconds require sign-in. Code, sound, and experimentation — with more ways to find your next idea.

LuSID Synthesizer — a SID-inspired SwiftUI synth with a synthwave heart. 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.
