dexed-py

Python bindings for the Dexed DX7 synthesizer, with support for high-level patch editing, ML/JAX workflows, and low-level parameter arrays.

Source: github.com/DBraun/dexed-py | PyPI: dexed-py

An llms.txt file is available for LLM context.

Features

• High-level Patch API for creating and editing DX7 patches with named parameters

• DX7 sysex support for loading and saving .syx bank files and individual voice dumps

• Preset — ML/JAX interface with 145-element normalized flat arrays, full JAX PyTree support, and zero JIT recompilation overhead

• Custom operator graphs that go beyond the 32 fixed DX7 algorithms (arbitrary topologies, any number of operators)

• Per-operator rendering for analyzing individual operator contributions

• Algorithm metadata including carrier/modulator classification and modulation matrices

Requirements

• Python >= 3.11

• NumPy

• Optional: JAX for PyTree integration
