Work - Midi To Bytebeat

Once you master the translation, the real art begins. Instead of simply replicating the MIDI, you augment it.

MIDI has velocity and note-off events. Bytebeat, in its purest form, has no volume envelopes. A note is either "playing" or "not playing."

Converters solve this by generating gating sequences. When a MIDI note ends, the converter doesn't just stop the wave; it multiplies the wave by (t < note_end_time). This creates a hard, abrupt stop (a "gate") rather than a smooth release. If you want reverb or decay, you have to cheat by adding a division term like /( (t>>12) & 7 ).

MIDI and bytebeat come from two different eras: one designed for interoperability, the other for minimalism and discovery. Bridging them isn’t about replacing either—it’s about seeing what music becomes when you force precise notation through a wild, arithmetic lens.

So if you’ve ever wanted your elegant MIDI composition to scream through a pocket calculator from 1977, you know what to do. Write the notes. Export the math. Let t do the rest.

Converting MIDI to bytebeat essentially translates "notes" (discrete musical instructions) into "math" (a continuous algorithmic stream). While they are fundamentally different ways of making sound, you can bridge them through specific tools and mathematical techniques. How Conversion Works

Standard bytebeat is a single line of code (like (t*5&t>>7)|(t*3&t>>10)) where

is a counter incremented at a fixed sample rate (usually 8kHz). To integrate MIDI: Variable Pitch: Instead of a fixed , tools use a modified counter (often called

) that speeds up or slows down based on the MIDI note frequency.

Control Mapping: MIDI CC values (0–127) are used as variables within the equation to live-tweak parameters like distortion, rhythm, or filtering. Notable Tools & Methods

Websynth (Stellartux): A prominent JS-based bytebeat tool that includes a "keyboard mode." It maps MIDI notes so the function plays the correct pitch relative to the keyboard input. Prismatic Spray Go to product viewer dialog for this item.

: These are hardware bytebeat synthesizers that accept standard 5-pin or TRS MIDI. They allow for "MIDI reset," which restarts the equation every time a new note is pressed, making the math behave more like a traditional playable instrument.

Custom Converters: While automated "MIDI-to-Expression" converters exist in hobbyist circles, they are often unstable or limited to simple monophonic melodies because bytebeat struggles with polyphony (harmony) unless you manually add multiple equations together (e.g., (eq1) + (eq2)).

Sample Rate Matters: Most bytebeats expect an 8kHz output. If your MIDI system is running at 44.1kHz, the "standard" math will sound extremely high-pitched.

Use Bitwise Operators: To make MIDI velocity or CC values feel "crunchy" and native to bytebeat, use them with bitwise AND (&) or XOR (^) instead of standard multiplication.

Midi to bytebeat work involves converting standard MIDI note data

(like pitch and timing) into algorithmic mathematical formulas that generate audio as a stream of raw 8-bit bytes. Instead of using samples, these tools map MIDI inputs to variables in an expression—typically using the time variable —to synthesize crunchy, glitchy music in real-time. Core Mechanics Pitch Conversion

: MIDI note numbers are sent to a bytebeat function that calculates the appropriate frequency. For example, a note's frequency can be derived from its MIDI number using the formula Variable Incrementing : In many web-based synths, the variable

is incremented at a rate relative to the note played, ensuring the resulting formula produces the correct pitch. Rhythmic Synchronization : Secondary counters (often called

) may be used to maintain a consistent tempo (BPM) regardless of which note is being triggered. Notable Tools and Resources

Common bytebeat formulas often use bitwise operators to create complex patterns: Sierpinski Harmony t & t >> 8 (creates a fractal-like self-similar sound). Glitch Patterns t * ((t>>12|t>>8)&63&t>>4) (generates rhythmic, evolving structures). Python script Once you master the translation, the real art begins

that generates a simple bytebeat audio file from a set of MIDI-style note numbers?

Bytebeat operates on integer math. To make a note, you create a periodic wave. The classic formula for a square wave tone is (t >> N) & 1. But here, N controls the pitch.

A standard MIDI note number (e.g., 60 = Middle C) must be converted into a period increment. The converter calculates the number of samples needed for one full cycle of that frequency (Sample Rate / Frequency). It then generates a delta_t step value. In many Bytebeat expressions, this looks like t * (freq * constant) >> 14.

Note: these are illustrative patterns — adapt to your parser and environment.

A. Simple step-based square-wave melody (pseudocode JS) Parse MIDI into note events

// presupposes an array steps = [midi_note_or_0,...] and stepSamples
let SR=8000, stepSamples=SR/4; // quarter-second steps
function midiToFreq(n) return 440*Math.pow(2,(n-69)/12); 
for(t=0;t<loopLen;t++)
  let step = Math.floor((t%loopLen)/stepSamples);
  let n = steps[step];
  if(n==0) sample=0;
  else 
    let f = midiToFreq(n);
    sample = ((t * f / SR) & 1) ? 255 : 0; // crude square
out = sample & 255;

B. Bytebeat-style integer expression using a pitch table

// table holds integer period values (samples per cycle) for each note
let table = [/* precomputed period integers for MIDI notes used */];
for(t=0;t<loopLen;t++)
  let step = (t >> 11) % table.length; // coarse clock
  let p = table[step];
  sample = ((t % p) < (p>>1)) * 128; // square using integer math
  out = sample & 255;

C. Derived minimal one-line bytebeat idea

(These minimal forms need a host loop to update noteIndex per step based on your parsed MIDI.)

This is the most direct, brute-force method. You analyze a MIDI file for its note events. You then construct a Bytebeat formula that acts as a Time-Indexed Synthesizer.

How it works: You hardcode a lookup table into the Bytebeat formula. For example:

note_sequence = 1000: 60, 2000: 62, 3000: 64

Then, your Bytebeat formula uses the time variable t to check which note should be playing at that exact sample. You map the MIDI pitch (60, 62, 64) to a frequency table, and output a sine wave (or square wave) of that frequency.

The formula looks like: (t>>12) & 1 ? sin( lookup_note( t ) * t ) : 0

Pros: Exact note replication. Works for polyphony. Cons: Generates huge formulas. Not pure "math music"—it’s just a MIDI player written in bytebeat syntax.

Let’s say your MIDI had a simple bassline:

The converter might produce: ((t>>13)&1)*((t*(4+((t>>11)&3)))&128) | ((t>>14)&1)*((t*6)&255)

The first term is the kick (the (t>>13)&1 creates a low-frequency pulse). The second term is the bass. Notice the &128 vs &255—that’s the converter preserving the different velocities (kick is loud, bass is quiet).

When you paste this into a live Bytebeat player (like the one on Greasemonkey or Wurstcaptor), you aren't playing the song. You are solving the song. Each sample is a new answer to the equation.
