Marble Melody vs Bytebeat

A marble bounces down glass plates, and every bounce plays one note of the song. Marble Melody brings the "marble music box" videos you've seen online to your phone. ■ One thing to do Pick a song and drop the marble. The plates are laid out automatically for each song, and every bounce plays the right note. Just watch, and let the quiet moment pass. ■ 110 songs included Classical favorites (Minuet in G, Air on the G String, Moonlight Sonata, Gymnopédie, Canon in D...), nursery rhymes, Japanese school songs, seasonal songs and folk tunes from around the world. All songs are in the public domain, performed by the app's own music-box sound. ■ Play mode: tap to the rhythm Tap the instant the marble hits a plate. Hit it and the note rings out; miss it and it fades. Perfect / Good / Miss judging, combos, a rank (S/A/B/C) per song and your own best score. Switch between Listen and Play right from the home screen. ■ Sleep mode Quiet songs play one after another without a break, then fade out and stop after 15, 30 or 60 minutes. While it plays, the stage turns to a dark night scene. Made for bedtime. ■ Song of the day reminder Get a gentle reminder of the day's song at the time you choose (in Settings; off by default). Your listening streak shows on the Song of the day card. ■ Play your own tunes - Tap composer: place notes on a grid - Import MIDI files (the main melody is extracted automatically) - Share your songs as MIDI with friends ■ Themes Classic, Pastel, Night, Candy, Ocean, Forest, Sakura, Sunset, Neon, Space, Retro and Mono. ■ Settings Light/dark appearance, volume, plate glow on hit, haptics. ■ Premium (optional) - No ads - Every song, anytime - All themes Without Premium, today's song and most songs are free to play.

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.
