From Piano Roll to Pure Math: A Deep Dive into MIDI to Bytebeat Conversion

If you’ve spent any time in the corners of the internet dedicated to algorithmic music—places like Reddit’s r/bytebeat, Demoscene forums, or the Collatz conjecture fan clubs—you’ve likely stumbled upon a strange, mesmerizing phenomenon: Bytebeat.

It sounds like an 8-bit chiptune being fed through a malfunctioning oscilloscope. It’s raw, glitchy, and impossibly complex. Yet, it is generated by a single line of mathematical logic. But here’s the kicker: as a musician, you don’t have to write that math from scratch. You can export a standard MIDI file from your DAW and translate it directly into a Bytebeat equation.

Today, we’re pulling back the curtain on the MIDI to Bytebeat pipeline—the bridge between your piano roll and pure, real-time mathematics.

What this does

Convert melodic/harmonic MIDI data into simple bytebeat formulas (tiny JS expressions producing audio when sampled at 8000–44100 Hz). This guide gives a workflow, examples, and tips to retain musical structure.


1. Data-driven bytebeat

Encode MIDI data as lookup tables inside the formula. For example, store note values in an array indexed by t >> shift (time division). The bytebeat function then reads from that table as time advances, effectively playing a sequenced melody. midi to bytebeat work

Part 4: The Deep Engineering – Translating Pitch to Bytebeat Math

The core technical challenge in midi to bytebeat work is frequency generation. MIDI note numbers are logarithmic; Bytebeat requires linear oscillation.

The formula for converting MIDI note number to Bytebeat frequency:

frequency = 440 * 2^((note_number - 69) / 12)

Once you have the frequency, you must implement an oscillator using integer math only (true Bytebeat). Here are common Bytebeat oscillators:

Now, to play a MIDI sequence, your Bytebeat code must switch between these frequencies based on t. A simplified version looks like: From Piano Roll to Pure Math: A Deep

// Pseudo-bytebeat for MIDI note C4 (262Hz) for 1 second, then D4 (294Hz)
char *song = 
   "t < 44100 ? (t*262%256) : "
   "(t < 88200 ? (t*294%256) : 0)";

Of course, this grows exponentially with longer sequences. Advanced tools use loop compression and modular arithmetic to pack entire songs into 100 characters.

Despite its magic, midi to bytebeat work is not perfect.

2. Polyphenyl via Bitwise OR

MIDI files usually have multiple tracks or channels. In a standard synthesizer, you mix these tracks by adding their audio signals. You cannot do that in Bytebeat. Once you have the frequency, you must implement

Adding two signals in Bytebeat causes clipping and distortion. Instead, the smart converters use bitwise OR (|) or XOR (^) to combine voices. If Track A generates bits 1001 and Track B generates bits 0110, the OR result is 1111. This creates a unique, crunchy "channel stacking" effect that sounds like a vintage arcade machine.
