Quantum Generative MIDI

Quantum MIDI Sequencer

This is a real-time generative MIDI sequencer powered by quantum circuits using Qiskit and Mido.

What does it do?

• Generates MIDI note sequences based on the output of a quantum circuit.
• Uses multiple qubits and random gates (h, x, rz, swap, cx) to create unique combinations.
• Runs multiple shots per execution to produce chords or simultaneous layers.
• Incorporates quantum LFOs for:
  • Real-time modulation of velocity (note intensity).
  • Smooth variation of note duration via an accumulative LFO.

Quantum Circuit Features

• Each qubit receives a random gate (h, x, or rz) on each cycle.
• Random swaps occur between pairs of qubits.
• Some fixed entanglements are added (cx(0,1) and cx(1,7)) for deeper interaction.
• Measurement results are converted directly into MIDI notes.

Quantum Modulation

• get_quantum_lfo() produces smoothly distributed random values using multiple qubits.
• QuantumSmoothLFO simulates a slow oscillating LFO to vary note duration dynamically.

Requirements

• Python 3.8+
• loopMIDI (or any virtual MIDI port)
• Dependencies:

pip install qiskit qiskit-aer mido python-rtmidi
