Bytebeat handles one note at a time best. While polyphony (chords) is mathematically possible by adding formulas together—e.g., (formula1) + (formula2) —it quickly distorts due to the 8-bit clipping limits.
Converting MIDI to Bytebeat isn’t just an academic exercise; it offers unique creative and technical advantages.
Because floating-point numbers are tricky in pure bitwise bytebeat, developers often map MIDI note numbers to an array of pre-calculated integer frequency scalers. Step 2: Handling Note Durations and Sequencing
MIDI Track 10 is reserved for percussion (kick, snare, hi-hats). A MIDI-to-Bytebeat converter detects these notes and replaces continuous pitch equations with pseudo-random noise equations or rapid exponential decay functions triggered by the timing sequence.
You can use a structured MIDI file (a melody or chord progression) to control the otherwise random-seeming output of a bytebeat formula.
Converting MIDI to Bytebeat involves translating structured MIDI event data (notes, velocity, timing) into a single mathematical formula that generates 8-bit audio samples over time.
Where m is determined by the MIDI note, and c is a constant that creates the texture. 3. Implementation Tools
: To make a bytebeat "playable" via MIDI, the time variable t must be scaled by a frequency factor derived from the MIDI note number ( Method 1: Using Online Tools & Translators
SPB=Seconds Per Beat×SR=0.5×8000=4000 samplesSPB equals Seconds Per Beat cross cap S cap R equals 0.5 cross 8000 equals 4000 samples
). In Bytebeat, a basic sawtooth wave at a given frequency is generated by . Since MIDI note follows the formula , the Bytebeat equivalent for a note is often written as: sampleRate
Because you are reading this, you likely want to actually do the conversion. Here are the current best tools and techniques.
Use a library like mido (Python) or @tonejs/midi (JavaScript) to extract an array of note objects containing note, start_time, duration .

When executed at a standard sample rate (such as 8000Hz or 11025Hz), this simple formula yields complex, rhythmic, and evolving chiptune music. The output values are truncated to unsigned 8-bit integers (0 to 255) and sent directly to the audio hardware. The Challenge of Conversion
