The first obstacle in creating such a patch is reconciling two incompatible definitions of time. MIDI is discrete and event-driven; its timeline advances in ticks, waiting for triggers to play a specific note at a specific velocity for a specific duration. Bytebeat, however, is continuous and time-centric. Its only variable is t (time), which increments linearly, often at the sample rate (e.g., 44,100 times per second). A MIDI file asks, "What happens at beat 48?" while a Bytebeat function asks, "What is the value of t right now, and how does it relate to its own past?"
To bridge this gap, a patch must act as a real-time interpreter. The classic approach is to load a MIDI file into a bytebeat engine, scan its tracks for note events, and map each note’s pitch to a frequency and its duration to a range of t. The bytebeat formula then becomes a conditional state machine: if (t is within the start and end of Note 60), output sine wave at 261.63 Hz; else output 0. However, this naive method merely plays MIDI through a bytebeat speaker, missing the point entirely. True patching seeks something more radical: the translation of musical structure into arithmetic logic.
Let's build a simple, working patch in pseudocode that you can implement in Python (using mido and sounddevice) to understand the core logic.
import mido, sounddevice as sd, numpy as npt = 0 current_note = 60 # Middle C velocity = 64
def midi_callback(msg): global current_note, velocity if msg.type == 'note_on': current_note = msg.note velocity = msg.velocity
def bytebeat_callback(outdata, frames, time, status): global t for i in range(frames): # The PATCH: MIDI note becomes a divisor divisor = max(1, current_note // 4) # The PATCH: Velocity becomes a bitwise OR coefficient v_coeff = velocity // 2 midi to bytebeat patched
formula = ((t >> (divisor % 8)) | (t >> v_coeff)) & 0xFF outdata[i] = (formula / 128.0) - 1.0 t += 1
with mido.open_input(callback=midi_callback): sd.OutputStream(callback=bytebeat_callback, samplerate=44100).start() input("Playing MIDI to Bytebeat patched. Press Enter to stop.")
Run this script. Play a low note (C2). The sound is slow, crunchy, like a broken decoder ring. Play a high note (C6). The t division increases, generating high-pitched, screeching arpeggios. Twist your velocity—the texture changes from smooth to jagged. That is the patch.
Let’s be honest. Most attempts at this patch sound terrible. Not experimental—terrible. The issues include:
But the community embraces these as features. A well-patched system treats the keyboard as an exploration device, not a performance instrument. You don't play "Chopsticks." You search for the chaotic islands in the parameter space where a simple G note produces a rhythmic, evolving pattern over 10 seconds. The first obstacle in creating such a patch
Bytebeat is inherently monophonic because it is a single stream of math. However, you can simulate polyphony using ** MIDI Channels and Layering**.
If your environment supports it, you can create multiple Bytebeat "instances" (virtual voices).
This allows you to play chords. A low note on Channel 1 generates a bass drone, while a high note on Channel 2 generates a lead line. The interaction between the two mathematical formulas can create interference patterns—beating frequencies that evolve organically.
You might ask: "Why go through this? Just use a VST."
The answer lies in the word "Patched." In modular synthesis, a patch is temporary, fragile, and unique. A "MIDI to Bytebeat Patched" system is not an instrument; it is a condition. with mido
When you patch MIDI into Bytebeat, you break the fundamental assumption of Western tuning. MIDI was designed for equal temperament (A=440Hz). Bytebeat has no concept of pitch. It only has arithmetic overflow.
The patch forces a violent negotiation:
The result is a non-linear relationship. Playing louder doesn't make it louder; it makes it slower or inverted. This unpredictability is the entire point.
MIDI is the control voltage of the digital age. It deals in discrete events:
MIDI is safe. It represents intent. When you press middle C, you expect a sound that resembles middle C.
