settings

settings are saved when clicking the OK button at the bottom of the dialog.

General

Program

• Render backend
  • changing this may help with performace issues.
• Late render clear
• Power-saving mode: saves power by lowering the frame rate to 2fps when idle.
  • may cause issues under Mesa drivers!
• Disable threaded input (restart after changing!): processes key presses for note preview on a separate thread (on supported platforms), which reduces latency.
  • however, crashes have been reported when threaded input is on. enable this option if that is the case.
• Enable event delay
  • may cause issues with high-polling-rate mice when previewing notes.

File

• Use system file picker: uses native OS file dialog instead of Furnace's.
• Number of recent files: number of files to show in the open recent... menu.
• Compress when saving
  • uses zlib to compress saved songs.
• Save unused patterns
• Use new pattern format when saving
• Don't apply compatibility flags when loading .dmf
• Play after opening song:
  • No
  • Only if already playing
  • Yes
• Audio export loop/fade out time:
  • Set to these values on start-up:
    • Loops: number of additional times to play through 0Bxx song loop.
    • Fade out (seconds): length of fade out after final loop.
  • Remember last values

Chip

• Initial system: the system of chips loaded on starting Furnace.
  • Current system: sets current chips as default.
  • Randomize: sets default to a random system.
    • this will not choose a random system at each start.
  • Reset to defaults: sets default to "Sega Genesis/Mega Drive".
  • Name: name for the default system. may be set to any text.
  • Configure: same as in the chip manager and mixer.
• When creating new song:
  • Display system preset selector
  • Start with initial system
• Restart song when changing chip properties

Start-up

• Play intro on start-up:
  • No: skips intro entirely.
  • Short: shows silent title screen briefly.
  • Full (short when loading song): shows animated musical intro unless started with a song (command line, double-clicking a .fur file, etc.)
  • Full (always): always shows animated musical intro.
• Disable fade-in during start-up
• About screen party time
  • warning: may cause epileptic seizures.

Behavior

• New instruments are blank

Audio

Output

• Backend: selects SDL or JACK for audio output.
  • only appears on Linux, or MacOS compiled with JACK support
• Driver
• Device: audio device for playback.
• Sample rate
• Outputs: number of audio outputs created, up to 16.
  • only appears when Backend is JACK.
• Channels: number of output channels to use.
• Buffer size: size of buffer in both samples and milliseconds.
• Low-latency mode (experimental!): reduces latency by running the engine faster than the tick rate. useful for live playback/jam mode.
  • warning: experimental! may produce glitches. only enable if your buffer size is small (10ms or less).
• Force mono audio
• want: displays requested audio configuration.
• got: displays actual audio configuration returned by audio backend.

Mixing

• Quality: selects quality of resampling. low quality reduces CPU load.
• Software clipping: clips output to nominal range (-1.0 to 1.0) before passing it to the audio device.
  • this avoids activating Windows' built-in limiter.
