Tonkro vs Bytebeat

MAKE MUSIC BY TOUCHING THE MACHINE Tonkro is a playful music workstation for iPad: part synthesizer, sampler, drum machine, sequencer, recorder, editor, mixer, and DJ performance space. SHAPE ORIGINAL INSTRUMENTS Explore distinctive synth and drum engines through four expressive controls. Each workshop is built to feel immediate: touch the illustrated machinery, hear the result, and let the characters react to your performance. SAMPLE THE WORLD Record through the microphone or import audio. Play one sound chromatically, divide it into untransposed slices, or map multiple samples across keys and pads. Trim, crop, loop, reverse, fade, change speed, transpose, and preserve the original recording with non-destructive editing. FIND RHYTHMS YOUR WAY Seven sequencer personalities turn taps, held notes, patterns, gestures, and playful systems into musical motion. Tempo, transport, MIDI, and recording stay connected, so a sketch can become an arrangement without breaking the flow. RECORD AND ARRANGE Build with eight stereo tracks. Record audio or notes, edit clips and piano-roll performances, overdub, punch, loop, lift, drop, mix, export stems, and save portable project bundles. PERFORM WITH MONSTER DECKS Load two tracks, set beat grids, sync, use key lock, cue points, hot cues, quantized loops, EQ, filters, pitch bend, and the crossfader. Record the performance or print it directly into the tape arrangement. MADE FOR PLAY Tonkro keeps its creative tools visible, touchable, and full of character. It works without an account, advertising, or third-party analytics. Your projects, recordings, and imported samples remain on your iPad unless you choose to export or share them.

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.
