The required library can be found here: https://github.com/marcel-licence/ML_SynthTools Version 1.2.0 will be required (will be released soon)

Supported versions of board library

This project is an example supporting the following platforms:

  • ESP32, RP2040: for more details look here

I would recommend to take a look at the loaddata_examples.ino Here you would find different possibilities to load data into the sampler:

  • single wav file to preset (all keys used for playback of the same sample with different pitch)
  • wav files to different keys (each key can playback another sample)
  • folder to different keys (wav files contained in a folder mapped to different keys)
  • folder to presets (each file found in a folder will be used as a new sound)
  • samples from soundfont (ignoring the rest within the soundfont the samples only will be loaded)
  • instruments from soundfont (this allows to get key mapping: notes and velocity)
  • load complete soundfont (the sample data will be copied completely and loading the properties)

Some features of soundfonts are not supported (like modulators etc.)

More information will be available in future

download & compile

Step 1: Download and Install ML_SynthTools and ML_SynthTools_Lib

  • Navigate to the ML_SynthTools GitHub repository: ML_SynthTools and follow the instructions
  • Navigate to the ML_SynthTools_Lib GitHub repository: ML_SynthTools_Lib and follow the instructions

Step 2: Download the Arduino project

  • Navigate to the ml_synth_sampler_example GitHub repository: [ml_synth_sampler_example](https://github.com/marcel-licence/ML_SynthTools.
  • Click the green Code button and select Download ZIP.
  • Extract the contents of the zip-archive to a directory of your choice

Step 3: Open the project

  • locate ml_synth_sampler_example.ino in your project folder and open it within the Arduino IDE

Step 4: Choose your configuration

  • This project might be compatible for different configurations. You could choose the ESP32 in your board manager as an example. Compatible and tested configurations are listed here: board_info

Step 5: Run the compilation

  • You can run the compiler

Step 6: Upload the firmware

  • Finally, you can upload the firmware

Step 7: Check your hardware configuration

  • It is higly recommended to open the serial monitor. It displays some pin settings for different components like the audio codec and other used pins
