Bytebeat vs InkyTune

t*(42&t>>10) That one line is the whole song. Bytebeat turns a formula straight into sound. It evaluates your expression while t counts up from zero, one step at a time, and writes the result out as the waveform. No synthesizer, no audio files, no samples. The formula is the music. ■ Edit while it plays - Rewrite the formula without stopping playback. t keeps running - Change a single character and the song becomes something else - A keypad holding only the characters that appear in bytebeat formulas, so one tap is one character ■ See the waveform - An oscilloscope draws the samples that are actually playing - Traces are aligned to the rising edge, so the wave stays still instead of scrolling - Instruction count and stack depth are shown too ■ 29 famous formulas - Includes the one-liners from the experiments viznut published in 2011 - Save the ones you like to favorites with your own names ■ Three modes - Bytebeat: result & 255 mapped to 0...255, the way the original sounded - Signed: treated as signed 8-bit - Floatbeat: the result used directly as a -1...1 waveform, where sin and cos come alive ■ Change the speed of t - 500 to 48000 Hz. The original bytebeat ran at 8000 Hz - Slower runs lower, faster runs higher ■ Export to WAV - 8-bit, 8000 Hz, mono, which is exactly what bytebeat is - 10 seconds, 30 seconds, 1 minute or 3 minutes ■ What you can write - The variable t, and the constants PI and E - Arithmetic, bitwise operators, shifts, comparison, logic, the ternary operator - sin cos tan asin acos atan abs floor ceil round sqrt exp log sign int pow min max atan2 mod - Everything is computed in Double and rounded to 32-bit integers only for bitwise operations and shifts. This matches JavaScript's ToInt32, so formulas you find on the web play as they are ■ No connection - No account to create - No ads, no tracking - The app never connects to the internet. It works on a plane Many of the presets come from the experiments Ville-Matias Heikkila (viznut) published in 2011.

You don’t need music theory to finish a song. InkyTune is a digital music sketchbook you can actually play. Draw a line with your finger or Apple Pencil, and your stroke becomes a rhythm- and scale-aware melody. InkyTune then builds matching chords, bass, drums, and atmosphere around it. Finish drawing, tap Play, and hear your idea become a complete arrangement. DRAW YOUR MELODY • Horizontal movement controls time • Vertical movement controls pitch • Even a short tap can create a note • Timing and pitch are shaped into a musical result • The rise, fall, and movement of your original line are preserved • Draw with your finger or Apple Pencil FIND YOUR VIBE Choose from Lo-Fi, Pop, House, Chiptune, Ambient, Jazz, and Synthwave. These are more than visual themes. Every style has its own tempo, groove, drum pattern, chord language, bass movement, sound character, and energy curve. SHAPE THE MUSIC, NOT THE THEORY • Energy: calm to intense • Mood: dark to bright • Complexity: simple to rich These three approachable controls make audible changes to tempo, dynamics, harmony, rhythm density, and arrangement detail—without exposing a complicated mixer or piano roll. KEEP WHAT YOU LOVE Mute, lock, or regenerate individual chord, bass, drum, and atmosphere layers. Lock the parts you like, then try another random seed to explore a new variation. Your drawn melody remains yours. PLAY, SAVE, AND SHARE • Play, pause, stop, and loop • Automatically save and restore your latest project • Create and manage multiple musical sketches • Export real WAV, AIFF, or M4A audio files • Share your finished track with the system share sheet • Designed for both iPhone and iPad Core creation and music generation run directly on your device. No account, cloud service, or internet connection is required. Want to go further? InkyTune includes Doodle Synth and Doodle FX extensions for compatible AUv3 music apps. Save a song’s style, controls, and random seed to the AUv3 Shared Library, then recall its matching sound preset inside either extension. One purchase. No subscription. No in-app purchases. Draw a melody. Make a song.
