Automatic FM patch programmer with Genetic Algorithm

fmprog

Automatic FM patch programmer with Genetic Algorithm

This generates a FM instrument for OPN2/OPNA to match a reference sound file.

How to build

You will need:

• build-essential
• git
• cmake
• libaubio-dev
• qtbase5-dev
• qtmultimedia5-dev
• libqt5multimedia5-plugins

Download sources

git clone --recursive https://github.com/jpcima/fmprog.git

Compile the program

mkdir fmprog/build
cd fmprog/build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
cmake --build .

The program FMProg will be found inside the build folder.

How to use

1. Load a sound file.

Click Load and select a reference sound file. Ideally this file is a clean recording of a playing note, without silence at the beginning nor at the end. You can try examples/Marimba.wav.

The program guesses the pitch and displays it in the Pitch box. You can change this value.

2. Run the algorithm

You can choose the targeted FM chip in the FM clock box.

Then, click Start. As it computes, the Gen number will increase. It can be suspended at any moment by clicking Pause,

3. Save the result

You may hear the current result by clicking Play. When it is satisfying enough, record the instrument by clicking Save.
