# developer info
|
|
|
|
[](https://github.com/tildearrow/furnace/actions/workflows/build.yml)
|
|
|
|
if you can't download these artifacts (because GitHub requires you to be logged in), [go here](https://nightly.link/tildearrow/furnace/workflows/build/master) 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.**
|
|
|
|
## dependencies
|
|
|
|
- CMake
|
|
- SDL2
|
|
- zlib
|
|
- JACK (optional)
|
|
|
|
SDL2 and zlib are included as submodules.
|
|
|
|
## getting the source
|
|
|
|
type the following on a terminal/console: (make sure Git is installed)
|
|
|
|
```
|
|
git clone --recursive https://github.com/tildearrow/furnace.git
|
|
cd furnace
|
|
```
|
|
|
|
(the `--recursive` parameter ensures submodules are fetched as well)
|
|
|
|
## compilation
|
|
|
|
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 ..
|
|
make
|
|
```
|
|
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>`
|
|
Example: `cmake -DBUILD_GUI=OFF -DWARNINGS_ARE_ERRORS=ON ..`
|
|
|
|
Available options:
|
|
|
|
| Name | Default | Description |
|
|
| :--: | :-----: | ----------- |
|
|
| `BUILD_GUI` | `ON` | Build the tracker (disable to build only a headless player) |
|
|
| `WITH_JACK` | `ON` if system-installed JACK detected, otherwise `OFF` | Whether to build with JACK support. Auto-detects if JACK is available |
|
|
| `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_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 |
|
|
|
|
## usage
|
|
|
|
```
|
|
./furnace
|
|
```
|
|
|
|
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.**

# notes
|
|
|
|
> how do I use Neo Geo SSG envelopes?
|
|
|
|
the following effects are provided:
|
|
|
|
- `22xy`: set envelope mode.
|
|
- `x` sets the envelope shape, which may be one of the following:
|
|
- `0: \___` decay
|
|
- `4: /___` attack once
|
|
- `8: \\\\` saw
|
|
- `9: \___` decay
|
|
- `A: \/\/` inverse obelisco
|
|
- `B: \¯¯¯` decay once
|
|
- `C: ////` inverse saw
|
|
- `D: /¯¯¯` attack
|
|
- `E: /\/\` obelisco
|
|
- `F: /___` attack once
|
|
- if `y` is 1 then the envelope will affect this channel.
|
|
- `23xx`: set envelope period low byte.
|
|
- `24xx`: set envelope period high byte.
|
|
- `25xx`: slide envelope period up.
|
|
- `26xx`: slide envelope period down.
|
|
|
|
a lower envelope period will make the envelope run faster.
|

# frequently asked questions
|
|
|
|
> 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`.)
|
|
|
|
> Q: how do I use PCM on a PCM-capable system?
|
|
|
|
A: Two possibilities: the recommended way is via creating the "Amiga/Sample" type instrument and assigning sample to it, or via old, Deflemask-compatible method, using `17xx` effect
|
|
|
|
> Q: my song sounds very odd at a certain point
|
|
|
|
A: file a bug report. use the Issues page. it's probably another playback inaccuracy.
|
|
|
|
> Q: my song sounds correct, but it doesn't in DefleMask
|
|
|
|
A: file a bug report **here**. it still is a playback inaccuracy.
|
|
|
|
> Q: my C64 song sounds terrible after saving as .dmf!
|
|
|
|
A: that's a limitation of the DefleMask format. save in Furnace song format instead (.fur).
|
|
|
|
> Q: how do I solo channels?
|
|
|
|
A: right click on the channel name.
