MIDI music is a style centered on composing and distributing music as Standard MIDI Files (.mid), using General MIDI (GM) instrument maps and channel conventions rather than recorded audio. Characterized by the hallmark timbres of GM-era synth modules and sound cards (e.g., Sound Canvas pianos, synth brass, slap bass, orchestral hits, and the Channel 10 drum kit), it embraces the sequenced, quantized feel of early PC games, DOS/Windows multimedia, and 1990s web pages that auto-played background MIDIs. Expressivity is driven by velocity, pitch bend, modulation, and controller messages, not microphone capture. Distinct from chiptune and tracker music, which target specific sound chips or module formats, MIDI music is portable across devices and soundfonts, producing a recognizable yet device-dependent aesthetic that evokes retro computing, early internet culture, and game nostalgia.

Bit music is a broad term for music built around the sound and constraints of low bit‑depth digital audio, early sound chips, and primitive computer/console hardware. It foregrounds square and pulse waves, noise channels, simple PCM, and the characteristic artifacts of bit‑crushing and low sample rates. While closely related to chiptune, bit music emphasizes the sonic signature of "the bit" itself: 1‑bit beeper techniques, 4/8/16‑bit sample playback, and tracker-based sequencing that exploits extremely limited polyphony and memory. The result is a bright, pixelated timbre that celebrates computational austerity through clever composition tricks, rapid arpeggios, duty‑cycle modulation, and noise percussion.
