Bitbop vs Bytebeat

Make music with your thumbs. Bitbop is a tiny chiptune groovebox - tap the colored pads to drop notes into a song while a little 8-bit band grooves underneath you: melody, bass, sparkle and drums. Here's the magic: every pad is in key, so you literally can't play a wrong note. Beginners make something that sounds great in seconds. There's nothing to read, no menus to learn - just tap and it grooves. FIVE SOUND ENGINES, NOT FIVE PRESETS Every mood is its own synthesizer, written from scratch: - BitBop - the signature chiptune voice: PWM lead and chip-supersaw - Rave - detuned supersaw and a saw reese bass, straight off a warehouse floor - Handheld - a faithful 4-channel console chip, real LFSR noise and all - Classical - plucked Karplus-Strong strings in a procedural hall - Dancehall - syncopated sub-bass, skank chop and a steppers riddim 600+ TUNES TO START FROM Load a public-domain classic, a folk tune, a rag, an anthem, a rave groove or an original chiptune sketch - then pull it apart and make it yours. Or hit Surprise and let Bitbop sketch a whole song for you. GO LIVE Start a live stream and anyone who opens your link watches your jam unfold in real time - your notes, your visuals, your beat, as you play it. No app needed on their end. Resume the same link later, or spin up a fresh one. MAKE IT LOOK GOOD Over 60 full-screen visualizers turn any jam into a light show - and what you see on screen is exactly what lands in your exported video. PLAY WITH IT - Tempo 65-250 bpm, swing, and a "vibe" filter; loops from 1 to 10 bars - Export your track as WAV or MIDI, or share it as a video clip - Share a song as a link - it opens the exact tune, in or out of the app PRIVATE BY DESIGN No accounts. No ads. No third-party trackers. Works fully offline. Your songs live on your device. Bitbop only sends anonymous usage counts (which you can turn off in Settings) - never your songs, never anything that identifies you. Tap a color. Make a banger. That's the whole app.

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.
