# 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. - **Per-channel oscilloscope threads**: runs the per-channel oscilloscope in separate threads for a performance boost when there are lots of channels. ### 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** - **Store instrument name in .fui**: when enabled, saving an instrument will store its name. this may increase file size. - **Load instrument name from .fui**: when enabled, loading an instrument will use the stored name (if present). otherwise, it will use the file name. ### New Song - **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](../8-advanced/chip-manager.md) and [mixer](../8-advanced/mixer.md). - **When creating new song**: - **Display system preset selector** - **Start with initial system** - **Default author name** ### 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**: when enabled, adding FM instruments will make them blank (rather than loading the default one). ## 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**: 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. - **DC offset correction**: apply a filter to remove DC bias, where the output is overall above or below zero. default is on. ### Metronome - **Volume**: sets volume of metronome. ### Sample preview - **Volume**: sets volume of sample preview. ## 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. - **Volume curve**: adjust the velocity to volume curve. - **Actions**: this allows you to bind note input and control change events to actions. - **`+`** button: adds a new action. - window-with-arrow button: new action with learning! press a button or move a slider/knob/something on your device. - each action has the following: - **Type**: type of event. - **Channel**: channel of event. - **Note/Control**: the note/control change number. - **Velocity/Value**: the velocity or control value - **Action**: the GUI action to perform. - **Learn**: after clicking on this button, do something in your MIDI device and Furnace will map that to this action. - **Remove**: remove this action. ### MIDI output - **MIDI output**: output device. - **Output mode:** - **Off (use for TX81Z)**: don't output anything. use if you plan to use Furnace as sync master, or the "Receive from TX81Z" button in the OPZ instrument editor. - **Melodic**: output MIDI events. - **Send Program Change**: output program change events when instrument change commands occur. - **Send MIDI clock**: output MIDI beat clock. - **Send MIDI timecode**: output MIDI timecode. - **Timecode frame rate**: sets the timing standard used for MIDI timecode. - **Closest to Tick Rate**: automatically sets the rate based on the song's Tick Rate. - **Film (24fps)**: output at 24 codes per second. - **PAL (25fps)**: output at 25 codes per second. - **NTSC drop (29.97fps)**: output at ~29.97 codes per second, skipping frames 0 and 1 of each minute that doesn't divide by 10. - **NTSC non-drop (30fps)**: output at 30 codes per second. ## Emulation ### Cores - **Playback Core(s)**: core(s) to use for playback. - **Render Core(s)**: core(s) to use when exporting audio. all of these are covered in the [guide to choosing emulation cores](../9-guides/emulation-cores.md). - **PC Speaker strategy**: this is covered in the [PC speaker page](../7-systems/pcspkr.md). ## Keyboard ### Keyboard - **Import** - **Export** - **Reset defaults** a list of keybinds is displayed. - click on a keybind. then enter a key or key combination to change it. - right-click to clear the keybind. - the full list is in the [keyboard](keyboard.md) page. #### note input the settings for note input keybinds operate differently. each entry in the list of keybinds is made of the following: - **Key**: key assignment. - **Type**: type of note input. left-click cycles through "Note", "Note off", "Note release", and "Macro release". - note: the list is sorted by type. on changing a key's type, it will instantly move to its new sorting position! - **Value**: number of semitones above C at the current octave. only appears for note type binds. - **Remove**: removes the keybind from the list. below all the binds, select a key from the dropdown list to add it. it will appear at or near the top of the list as a note with value 0. ## Interface ### Layout - **Workspace layout** - **Import**: reads a .ini layout file. - **Export**: writes current layout to a .ini file. - **Reset**: resets layout to default. - **Allow docking editors**: when enabled, you'll be able to dock instrument/wave/sample editors. -

**When cursor is in Note column**: only when the cursor is in the Note column - **When cursor is in Note column or not in edit mode**: erm... yeah. - **Always**: always preview notes. - **Allow dragging selection:** - **No**: don't allow drag-and-drop. - **Yes**: allow drag-and-drop. - **Yes (while holding Ctrl only)**: allow drag-and-drop but only when holding Control (Command on macOS). - **Toggle channel solo on:** selects which interactions with a channel header will toggle solo for that channel. - Right-click or double click - Right-click - Double-click - **Double click selects entire column**: when enabled, double clicking on a cell of the pattern will select the entire column. ### Cursor behavior - **Insert pushes entire channel row**: when enabled, pressing Insert will push the entire channel rather than the column at the cursor position. - **Pull delete affects entire channel row**: when enabled, pull deleting (Backspace by default) will pull the entire channel rather than the column at the cursor position. - **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. for example: - if off: moving the cursor onto the value `A5` and typing a "B" results in `0B`. - if on: moving the cursor onto the value `A5` and typing a "B" results in `5B`. - **Effect input behavior:** - **Move down**: after entering an effect (or effect value), the cursor moves down. - **Move to effect value (otherwise move down)**: after entering an effect, the cursor moves to its value. if entering a value, the cursor moves down. - **Move to effect value/next effect and wrap around**: after entering an effect or effect value, the cursor moves right. if it was on the last column, it jumps back to the first effect. - **Delete effect value when deleting effect**: if enabled, deleting effect will also delete its value. - **Change current instrument when changing instrument column (absorb)**: if enabled, typing on the instrument column will also select the instrument you've typed. - **Remove instrument value when inserting note off/release**: if enabled, inserting a note off or release on a row that has instrument value will remove the instrument value. - **Remove volume value when inserting note off/release**: same as above, but for volume. ### Cursor movement - **Wrap horizontally:** selects what to do when the cursor hits horizontal boundaries. - **No**: don't wrap the cursor. - **Yes**: wrap the cursor. - **Yes, and move to next/prev row**: wrap the cursor and move it to the other row. - **Wrap vertically:** selects what to do when the cursor hits vertical boundaries. - **No**: don't wrap the cursor. - **Yes**: wrap the cursor. - **Yes, and move to next/prev pattern**: wrap the cursor and go to the next/previous order. - **Yes, and move to next/prev pattern (wrap around)**: same as the previous option, but also wraps around the song. - **Cursor movement keys behavior:** allows you to select how much will the cursor move by when pressing cursor movement keys. - **Move by one**: guess. - **Move by Edit Step**: guess. - **Move cursor by edit step on delete**: when deleting, moves the cursor by Edit Step. - **Move cursor by edit step on insert (push)**: when inserting, moves the cursor by Edit Step. - **Move cursor up on backspace-delete**: when pull deleting (Backspace by default), moves cursor up. - **Move cursor to end of clipboard content when pasting**: allows you to choose what happens after pasting. - if on, the cursor will move to the end of the clipboard content. - if off, the cursor won't move. ### Scrolling - **Change order when scrolling outside of pattern bounds**: - **No**: the pattern edit cursor will stay locked within the current order. - **Yes**: moving the cursor past the edge of the previous or next order will move to that order, but not past the start or end of a song. - **Yes, and wrap around song**: as above, but will wrap from song end to start. - **Cursor follows current order when moving it** - applies when playback is stopped. - **Don't scroll when moving cursor** - **Move cursor with scroll wheel** - **No** - **Yes** - **Inverted** ## Appearance ### Scaling - **Automatic UI scaling factor**: automatically matches the OS's UI scaling. - **UI scaling factor**: only appears if "Automatic UI scaling factor" is off. - **Icon size** ### Text - **Font renderer**: this allows you to select which font renderer library to use. there are two choices: - **stb_truetype**: the original font renderer used in Furnace 0.6 and before. - **FreeType**: this font renderer has support for more font formats and provides more settings. introduced in Furnace 0.6.1. - **Main font**: font for the user interface. - **Header font**: font for section headers. - **Pattern font** font for the pattern view, the order list, and related. - if "Custom...", a file path selector will appear. - **Size**: font size. - **Display Japanese characters**, **Display Chinese (Simplified) characters**, **Display Chinese (Traditional) characters** and **Display Korean characters**: only toggle these options if you have enough graphics memory. - these are a temporary solution until dynamic font atlas is implemented in Dear ImGui. #### FreeType-specific settings - **Anti-aliased fonts**: when enabled, fonts will be rendered smooth. - **Support bitmap fonts**: this option allows you to enable the loading of bitmap fonts. - be noted that this may force non-bitmap fonts to undesired sizes! - **Hinting**: this option allows you to define how crisp fonts are rendered. - **Off**: disable font hinting. at small sizes, fonts may be blurry. - **Slight**: enable slight font hinting. - **Normal**: enable font hinting. - **Full**: enable harsh font hinting. fonts may look ugly/distorted to some people. - **Auto-hinter**: some fonts contain hinting data, but some don't. this allows you to select what happens. - **Disable**: only rely upon font hinting data. - **Enable**: prefer font hinting data if present. - **Force**: ignore font hinting data. ### Program - **Title bar:** - **Furnace** - **Song Name - Furnace** -
