Whether you use a lookup table, a genetic algorithm, or a live VCV Rack patch, the journey from MIDI to Bytebeat will fundamentally change how you hear all digital music.
Because bytebeat is the ultimate constraint. It forces you to hear music as pure sequence, as raw integer overflow, as the ghost in the machine. Converting MIDI to bytebeat is not about fidelity; it is about alchemy. You pour in the lead of your piano roll, and out comes the golden noise of the bare metal. midi to bytebeat

This is not a "pure" bytebeat (a single line of logic), but it is accepted in the demoscene as a hybrid bytebeat track. The magic happens when you modulate the lookup table's index using bitwise operations. If you want a pure formula—a single line of C like main(t)for(;;t++)putchar(t*((t>>12 —you cannot directly convert an arbitrary MIDI. You must reverse engineer. Converting MIDI to bytebeat is not about fidelity;
Your MIDI file becomes the rhythmic gate for a continuous bytebeat texture. This produces music that sounds impossibly complex given the tiny code size. As of 2025, we are seeing the rise of Neural Bytebeat . Researchers are training small RNNs (Recurrent Neural Networks) on MIDI datasets and then distilling the network into a bytebeat-style formula.
// The 'song' array: each entry is a pitch shift or 0 for silence. // Derived from your MIDI melody at 44.1kHz. char song[44100 * 30]; char get_note(int t) return song[t % (44100*30)];
// Trigger formula generated from MIDI kicks and snares char events[1024] = 1,0,0,1,0,1,0,0; // derived from MIDI for (int t = 0; t < 44100*60; t++) int trigger = events[t % 1024]; // Bytebeat drum synthesis int kick = (t * (t>>13 & 1)) & 255; int snare = (t>>9 & t>>7) & 255; output( trigger ? kick : snare );
