TinySoundFont-pybind

This tinysoundfont Python package provides Python bindings for TinySoundFont and lets you generate audio using SoundFont instruments (.sf2, .sf3, or .sfo files) in Python. The audio data can be played by PyAudio in a separate thread if requested. This package also includes support for loading and playing MIDI data using a SoundFont instrument.

What you might want to use this package for:

Play MIDI files with SoundFonts in Python
Play MIDI files with modifications and customizations (mute tracks, change instruments, etc.)
Procedurally generate and play music or sounds
Play music and sounds in an interactive way in your Python program

Installation

This package depends on pyaudio for playing sounds. To install pyaudio and tinysoundfont for common platforms:

Windows

py -m pip install pyaudio tinysoundfont

macOS

brew install portaudio
pip install pyaudio tinysoundfont

GNU/Linux (Ubuntu)

sudo apt install python3-pyaudio
pip install tinysoundfont

Basic Usage

Here is an example program that plays a chord:

import tinysoundfont
import time

synth = tinysoundfont.Synth()
sfid = synth.sfload("florestan-piano.sf2")
synth.program_select(0, sfid, 0, 0)
synth.start()

time.sleep(0.5)

synth.noteon(0, 48, 100)
synth.noteon(0, 52, 100)
synth.noteon(0, 55, 100)

time.sleep(0.5)

synth.noteoff(0, 48)
synth.noteoff(0, 52)
synth.noteoff(0, 55)

time.sleep(0.5)

Please see the Guide for more examples and notes about the examples.

Command line

The tinysoundfont package contains a simple command line tool that can be useful for finding presets, testing the validity of SoundFonts, and playing MIDI files.

Here is an example that loads the demo SoundFont and shows the presets it defines:

python -m tinysoundfont --info florestan-subset.sfo

(In Windows you may need to use py instead of python).

This results in:

Info for SoundFont florestan-subset.sfo
0 - 2 : Piano
0 - 10 : Music Box
0 - 12 : Marimba
0 - 19 : Church Org.1
0 - 21 : Accordion Fr
0 - 24 : Nylon-str.Gt
0 - 38 : Synth Bass 1
0 - 40 : Violin
0 - 45 : PizzicatoStr
0 - 55 : OrchestraHit
0 - 61 : Brass 1
0 - 75 : Pan Flute
0 - 87 : Bass & Lead
0 - 90 : Polysynth
0 - 97 : Soundtrack
0 - 109 : Bagpipe
0 - 116 : Taiko

The output format shows bank - preset : Name.

Here is an example that plays a test note using preset 55:

python -m tinysoundfont --test florestan-subset.sfo --preset 55 --key 70

Here is an example that plays a MIDI file using the FluidR3_GM SoundFont:

python -m tinysoundfont --play FluidR3_GM.sf2 1080-c01.mid
