settings

settings are saved when clicking the OK or Apply buttons at the bottom of the dialog.

General

Program

  • Render backend: changing this may help with performace issues.
  • Late render clear: this option is only useful when using old versions of Mesa drivers. it force-waits for VBlank by clearing after present, reducing latency.
  • 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 that will be remembered in the open recent... menu.
  • Compress when saving: uses zlib to compress saved songs.
  • Save unused patterns: stores unused patterns in a saved song.
  • Use new pattern format when saving: stores patterns in the new, optimized and smaller format. only disable if you need to work with older versions of Furnace.
  • Don't apply compatibility flags when loading .dmf: does exactly what the option says. your .dmf songs may not play correctly after enabled.
  • 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

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 a different backend for audio output.
    • SDL: the default one.
    • JACK: the JACK Audio Connection Kit (low-latency audio server). only appears on Linux, or MacOS compiled with JACK support.
    • PortAudio: this may or may not perform better than the SDL backend.
  • Driver: select a different audio driver if you're having problems with the default one.
    • only appears when Backend is SDL.
  • Device: audio device for playback.
    • if using PortAudio backend, devices will be prefixed with the audio API that PortAudio is going to use:
      • Windows WASAPI: a modern audio API available on Windows Vista and later, featuring an (optional) Exclusive Mode. be noted that your buffer size setting may be ignored.
      • Windows WDM-KS: low-latency, direct to hardware output mechanism. may not work all the time and prevents your audio device from being used for anything else!
      • Windows DirectSound: this is the worst choice. best to move on.
      • MME: an old audio API. doesn't have Exclusive Mode.
      • Core Audio: the only choice in macOS.
      • ALSA: low-level audio output on Linux. may prevent other applications from using your audio device.
  • Sample rate: audio output rate.
    • a lower rate decreases quality and isn't really beneficial.
    • if using PortAudio backend, be careful about this value.
  • Outputs: number of audio outputs created, up to 16.
    • only appears when Backend is JACK.
  • Channels: mono, stereo or something.
  • Buffer size: size of buffer in both samples and milliseconds.
    • setting this to a low value may cause stuttering/glitches in playback (known as "underruns" or "xruns").
    • setting this to a high value increases latency.
  • Exclusive mode: enables Exclusive Mode, which may offer latency improvements.
    • only available on WASAPI devices in the PortAudio backend!
  • Low-latency mode (experimental!): reduces latency by running the engine faster than the tick rate. useful for live playback/jam mode.
    • only enable if your buffer size is small (10ms or less).
  • Force mono audio: use if you're unable to hear stereo audio (e.g. single speaker or hearing loss in one ear).
  • 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 by a small amount.
  • 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.
    • this option shall be enabled when using PortAudio backend with a DirectSound device.

Metronome

  • Metronome volume

MIDI

MIDI input

  • MIDI input: input device.
  • Note input: enables note input. disable if you intend to use this device only for binding actions.
  • Velocity input: enables velocity input when entering notes in the pattern.
  • Map MIDI channels to direct channels: when enabled, notes from MIDI channels will be mapped to channels rather than the cursor position.
  • Map Yamaha FM voice data to instruments: when enabled, Furnace will listen for any transmitted Yamaha SysEx patches.
    • this option is only useful if you have a Yamaha FM synthesizer (e.g. TX81Z).
    • selecting a voice or using the "Voice Transmit?" option will send a patch, and Furnace will create a new instrument with its data.
    • this may also be triggered by clicking on "Receive from TX81Z" in the instrument editor (OPZ only).
  • Program change is instrument selection: changes the current instrument when a program change event is received.
  • Value input style: changes the way values are entered when the pattern cursor is not in the Note column. the following styles are available:
    • Disabled/custom: no value input through MIDI.
    • Two octaves (0 is C-4, F is D#5): maps keys in two octaves to single nibble input. the layout is:
      • - octave n -- octave n+1 -
      • 1 3 6 8 A D F # # #
      • 0 2 4 5 7 9 B C E # # # # #
    • Raw (note number is value): the note number becomes the input value. not useful if you want to input anything above 7F.
    • Two octaves alternate (lower keys are 0-9, upper keys are A-F): maps keys in two octaves, but with a different layout:
      • - octave n -- octave n+1 -
      • A B C D E F # # # #
      • 0 1 2 3 4 5 6 7 8 9 # # # #
    • Use dual control change (one for each nibble): maps two control change events to the nibbles of a value.
      • CC of upper nibble: select the CC number that will change the upper nibble.
      • CC of lower nibble: select the CC number that will change the lower nibble.
    • Use 14-bit control change: maps two control change events that together form a single 14-bit CC. some MIDI controllers do these.
      • MSB CC: select the CC containing the upper portion of the control.
      • LSB CC: select the CC containing the lower portion of the control.
    • Use single control change: maps one control change event. not useful if you want to input odd numbers.
      • Control: select the CC number that will change the value.
  • Per-column control change: when enabled, you can map several control change events to a channel's columns.

      • Note/Control: the note/control change number.
      • Velocity/Value: the velocity or control value

  • Send MIDI clock: output MIDI beat clock.
