## General
### Program
- **Render backend**
- changing this may help with performace issues.
- **Late render clear**
- **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.
- **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**
- **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

- **Backend**: selects SDL or JACK for audio output.
- only appears on Linux, or MacOS compiled with JACK support
- **Driver**
- **Driver**: select a different SDL audio driver if you're having problems with the default one.
- **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.
- 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.
- **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**
- 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.
- **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.

## MIDI
### MIDI input
- **MIDI input**: input device.
- **Note input**
- **Velocity input**
- **Map MIDI channels to direct channels**
- **Map Yamaha FM voice data to instruments**
- **Program change is instrument selection**
- **Value input style**:
- **Disabled/custom**
- **Two octaves (0 is C-4, F is D#5)**
- **Raw (note number is value)**
- **Two octaves alternate (lower keys are 0-9, upper keys are A-F)**
- **Use dual control change (one for each nibble)**
- **CC of upper nibble**
- **CC of lower nibble**
- **Use 14-bit control change**
- **MSB CC**
- **LSB CC**
- **Use single control change**
- **Control**
- **Per-column control change**
- **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.
