unofficial packages

Packaging status

some people have provided packages for Unix/Unix-like distributions. here's a list.

developer info

Build furnace

if you can't download these artifacts (because GitHub requires you to be logged in), go here instead.

NOTE: do not download the project's source as a .zip or .tar.gz as these do not include the project's submodules which are necessary to proceed with building. please instead use Git as shown below.


  • CMake
  • JACK (optional, macOS/Linux only)

if building under Windows or macOS, no additional dependencies are required. otherwise, you may also need the following:

  • libpulse
  • libx11
  • libasound
  • libGL

some Linux distributions (e.g. Ubuntu or openSUSE) will require you to install the -dev versions of these.

getting the source

type the following on a terminal/console: (make sure Git is installed)

git clone --recursive
cd furnace

(the --recursive parameter ensures submodules are fetched as well)


your typical CMake project.

Windows using MSVC

as of now tildearrow uses MinGW for Windows builds, but thanks to OPNA2608 this works again!

from the developer tools command prompt:

mkdir build
cd build
cmake ..
msbuild ALL_BUILD.vcxproj

macOS and Linux

mkdir build
cd build
cmake ..

Alternatively, build scripts are provided in the scripts/ folder in the root of the repository.

CMake options

To add an option from the command-line: -D<NAME>=<VALUE>

Available options:

Name Default Description
BUILD_GUI ON Build the tracker (disable to build only a headless player)
USE_RTMIDI ON Build with MIDI support using RtMidi
USE_SDL2 ON Build with SDL2 (required to build with GUI)
USE_SNDFILE ON Build with libsndfile (required in order to work with audio files)
USE_BACKWARD ON Use backward-cpp to print a backtrace on crash/abort
WITH_JACK ON if system-installed JACK detected, otherwise OFF Whether to build with JACK support. Auto-detects if JACK is available
SYSTEM_FFTW OFF Use a system-installed version of FFTW instead of the vendored one
SYSTEM_FMT OFF Use a system-installed version of fmt instead of the vendored one
SYSTEM_LIBSNDFILE OFF Use a system-installed version of libsndfile instead of the vendored one
SYSTEM_RTMIDI OFF Use a system-installed version of RtMidi instead of the vendored one
SYSTEM_ZLIB OFF Use a system-installed version of zlib instead of the vendored one
SYSTEM_SDL2 OFF Use a system-installed version of SDL2 instead of the vendored one
WARNINGS_ARE_ERRORS OFF (but consider enabling this & reporting any errors that arise from it!) Whether warnings in furnace's C++ code should be treated as errors
WITH_DEMOS ON Install demo songs on make install
WITH_INSTRUMENTS ON Install demo instruments on make install

console usage


this opens the program.

./furnace -console <file>

this will play a compatible file.

./furnace -console -view commands <file>

this will play a compatible file and enable the commands view.

note that these commands only actually work in Linux environments. on other command lines, such as Windows' Command Prompt, or MacOS Terminal, it may not work correctly.

frequently asked questions

woah! 50 sound chips?! I can't believe it!

yup, it's real.

where's the manual?

see papers/. it's kind of incomplete, but at least the systems (sound chips) section is there.

it doesn't open under macOS!

this is due to Apple's application signing policy. a workaround is to right click on the Furnace app icon and select Open.

how do I use C64 absolute filter/duty?

on Instrument Editor in the C64 tab there are two options to toggle these. also provided are two effects:

  • 3xxx: set fine duty.
  • 4xxx: set fine cutoff. xxx range is 000-7ff. additionally, you can change the cutoff and/or duty as a macro inside an instrument by clicking the absolute cutoff macro and/or absolute duty macro checkbox at the bottom of the instrument. (for the filter, you also need to click the checkbox that says volume macro is cutoff macro.)

how do I use PCM on a PCM-capable system?

two possibilities:

  • the recommended way is by creating the "Sample" type instrument and assigning a sample to it.
  • otherwise you may employ the DefleMask-compatible method, using 17xx effect.

my .dmf song sounds very odd at a certain point

file a bug report. use the Issues page. it's probably another playback inaccuracy.

my .dmf song sounds correct, but it doesn't in DefleMask

file a bug report here. it still is a playback inaccuracy.

my song sounds terrible after saving as .dmf!

the DefleMask format has several limitations. save in Furnace song format instead (.fur).

how do I solo channels?

right click on the channel name.
