# settings

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



# General

- **Workspace layout**
  - **Import**: reads a .ini layout file.
  - **Export**: writes current layout to a .ini file.
  - **Reset**: resets layout to default.

- **Initial system**: the system of chips loaded on starting Furnace.
  - **Current system**: sets current chips as default.
  - **Randomize**: set 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.
  - system configuration: same as in the [chip manager](../8-advanced/chip-manager.md) and [mixer](../8-advanced/mixer.md).

- **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.
- **When creating new song**:
  - **Display system preset selector**
  - **Start with initial system**

- **Double-click time (seconds)**: maximum time between mouse clicks to recognize them as a double-click.
- **Toggle channel solo on:** select which interactions with a channel header will toggle solo for that channel.
- **Push value when overwriting instead of clearing it**: in the order list and pattern editors, typing into an already-filled value will shift digits instead of starting fresh.
  - if off: moving the cursor onto the value `A5` and typing a "B" results in `0B`.
  - if on: with the cursor on the value `A5` and typing a "B" results in `5B`.
- **Move cursor up on backspace-delete**
- **Move cursor by edit step on delete**
- **Change current instrument when changing instrument column (absorb)**
- **Delete effect value when deleting effect**
- **Change order when scrolling outside of pattern bounds**:
  - if off, the pattern edit cursor will stay locked within the current order.
  - if on, moving the cursor past the edge of the previous or next order will move to that order.
- **Move cursor by edit step on insert (push)**
- **Move cursor to end of clipboard content when pasting**
- **Don't scroll when moving cursor**
- **Double click selects entire column**
- **Allow docking editors**
- **Don't raise pattern editor on click**
- **Focus pattern editor when selecting instrument**
- **Restart song when changing chip properties**
- **Use system file picker**: use native OS file dialog instead of Furnace's.
- **Only allow window movement when clicking on title bar**
- **Enable event delay**
  - may cause issues with high-polling-rate mice when previewing notes.
- **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!)**
  - threaded input 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.
- **Remember window position**
  - remembers the window's last position on start-up.
- **New instruments are blank**
- **Save unused patterns**
- **Compress when saving**
  - use zlib to compress saved songs.
- **Cursor follows current order when moving it**
  - applies when playback is stopped.
- **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**
- **Note preview behavior:**
  - **Never**
  - **When cursor is in Note column**
  - **When cursor is in Note column or not in edit mode**
  - **Always**
- **Wrap pattern cursor horizontally:**
  - **No**
  - **Yes**
  - **Yes, and move to next/prev row**
- **Wrap pattern cursor vertically:**
  - **No**
  - **Yes**
  - **Yes, and move to next/prev pattern**
- **Cursor movement keys behavior:**
  - **Move by one**
  - **Move by Edit Step**
- **Effect input cursor behavior:**
  - **Move down**
  - **Move to effect value (otherwise move down)**
  - **Move to effect value/next effect and wrap around**
- **Allow dragging selection:**
  - **No**
  - **Yes**
  - **Yes (while holding Ctrl only)**



# Audio/MIDI

- **Backend**: select SDL or JACK for audio output.
  - only appears on Linux, or MacOS compiled with JACK support
- **Device**: audio device for playback.
- **Sample rate**
- **Outputs**: select 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.
- **Quality**: selects quality of resampling. low quality reduces CPU load.
- **Metronome volume**
- **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**
- **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.

- **got:** displays actual audio configuration returned by audio backend.
