Midi To Bytebeat [better]
MIDI
The journey from (Musical Instrument Digital Interface) to Bytebeat represents a shift from "music as instructions" to "music as pure mathematics." The MIDI Era: Music by Instruction
When reviewing your converted code, manually edit the logic to add bit-shifts. A static lookup table is boring. Change: output[ t ] to output[ t >> 3 ] to slow the melody by 8x and drop it into bass territory. Change & 63 to restrict the octave range. midi to bytebeat
- Square: (t / P) & 1 → scaled
- Pulse: ((t % P) < duty) ? high : low
- Saw: (t % P) scaled linearly
- Band-limited approximations: combine shifted saws/bitmasks to reduce aliasing.
- Use bitwise ops and shifts for rich, cheap timbres: e.g., ((t * k) ^ (t >> m)) & mask.
Bytebeat
Popularised around 2011 by Finnish programmer Ville-Matias Heikkilä (viznut), discarded the need for separate instruments or scores. Instead, it uses a single-line formula—often just a few characters of C or JavaScript code—to generate audio. In Bytebeat, the variable MIDI The journey from (Musical Instrument Digital Interface)

: Presented at the Audio Developer Conference, this talk/paper explores using simple formulas as control sources for synthesizer parameters like pitch and amplitude. Crucially, it demonstrates that these formulas can generate sequences of MIDI notes to feed external synthesizers. Square: (t / P) & 1 → scaled Pulse: ((t % P) < duty)
) is manipulated by the MIDI "number" (note value) to set specific frequencies. Virtual Keyboards : Some web-based composers, such as those on Greggman's HTML5 Bytebeat
