These MIDI bind functions can also be used during <page text="demo playback">Demos</page> for cinematic-related commands. ##MIDI Hardware vs Software The first consideration is whether you want to use a MIDI hardware setup or a software solution. If you're planning to use a **MIDI hardware** device, for example a [MIDI keyboard](https://en.wikipedia.org/wiki/MIDI_keyboard) or controller, you can simply plug the device into your machine via USB and begin setting up convars. If you're instead looking to use **MIDI software**, for example a MIDI controller app on your phone/tablet or an Elgato Stream Deck, you will first need to set up a virtual MIDI port on your system.

This setting will be saved to your user configuration and recalled on restart. ##Debug Mode To verify that Rust is listening to messages sent from your MIDI device, use the command `midiconvar.debugmode 1` Once enabled, start pressing down on keys or moving knobs/sliders on the MIDI device connected to your system. The console will print out the note numbers and knob values from your MIDI device in real-time. This command is useful for quickly identifying the note/knob number for specific keys and controls on your MIDI device, as well as the channel number for the note values. You can then use this info to setup your MIDI convar binds. #Convar Setup There are two main MIDI functions which can be assigned to convars in Rust: * Key Presses * Knobs / Sliders Before creating any binds, ensure you've [enabled MIDI convars](#enablemidiconvars) in the console first. ##Key Press Binds These are also known as note on/off MIDI behaviours - for example pressing a key on a MIDI keyboard or controller device. **Note ON** functions are indicated when a MIDI key/button is pressed down. **Note OFF** functions are indicated when a MIDI key/button is released. <note>In most cases you may only need to bind a single key press to a command, which is where 'note on' is useful. In other cases, you may want to bind a key release to a command to make a 'hold' key for calling commands, which is where 'note off' comes in handy.</note> To bind these functions in Rust, use the following commands: ###NOTE ON ``` midiconvar.bindkeyon <note> <channel> <convar> ``` For example: `bindkeyon 12 1 "graphics.dof 1"` will bind Note 12 on Channel 1 to set Depth of Field to true. This function means that when Note 12 is *pressed* on your MIDI device it will enable Depth of Field. ### NOTE OFF ``` midiconvar.bindkeyoff <note> <channel> <convar> ``` For example: `bindkeyoff 12 1 "graphics.dof 0"` will bind Note 12 on Channel 1 to set Depth of Field to false. This function means that when Note 12 is *released* on your MIDI device it will disable Depth of Field. These two *ON* and *OFF* examples together mean that Note 12 will become a 'hold' key - in other words, the Depth of Field effect (specified in the above convar parameter) will only be active whilst the note is being pressed down. ____ ##Knob and Slider Binds These are MIDI behaviours which have a value range between `0` and `1` - for example moving a slider to it's min/max. ``` midiconvar.bindknob <note> <channel> <convar> <min value> <max value> ``` For example: `bindknob 3 1 graphics.dof_focus_dist 0 50` will bind Knob 3 on Channel 1 to set the Depth of Field focus distance to range between a minimum value of 0 and a maximum of 50. This function means that turning (or sliding) Knob 3 on your MIDI device will adjust the focus point for the Depth of Field within the range specified. <note>If you have [debug mode](#debugmode) enabled, you can see the command along with the current knob range value printed in the console.</note> #Additional Commands Below are some additional commands useful for MIDI convar binding. ##Print Binds `midiconvar.printbindings` - Prints to console a list of all the MIDI notes and knobs bound to convars. MIDI binds are stored in the text file **convarbindings.txt** located in the ‘midi’ folder in your root game directory: ``` C:\Program Files (x86)\Steam\steamapps\common\Rust\midi\convarbindings.txt ``` ##Clear Binds `midiconvar.clearallbindings` - Removes all MIDI convar bindings. #MIDI Software Setup ##Virtual MIDI Port To use MIDI software for MIDI convar binds, you will first need to set up a virtual MIDI port on your system. One example is to use software such as [loopMIDI](https://www.tobias-erichsen.de/software/loopmidi.html) to create a MIDI loopback port to send MIDI notes through via other applications. Once installed, you simply create a port with a name of your choosing and let it run in the background.  You can now use the custom port you've created in a software of your choosing which supports MIDI to send notes to Rust. Below are a few software examples which make use of this setup. #Software Examples <note>Coming soon - WIP</note> ##Elgato Stream Deck ##Mobile/Tablet Apps #FAQ ##Who can use MIDI binds? MIDI convars can only be used by server admins or during demo playback. ##Will my MIDI hardware/device work with Rust? Theoretically, any MIDI device should work with MIDI convar binding in Rust. If your hardware is not being detected, it's likely the drivers or device itself has not been installed correctly. ##My MIDI binds aren't working! Make sure you have [enabled MIDI convars](#enablemidiconvars) in the console. You can also double check if your device is sending MIDI messages to Rust by using the [debug mode](#debugmode) command. ##What controller is being used in the video at the top of the page? The controller featured in [this demonstration clip](https://files.facepunch.com/wiki/files/739b0/8d833575a78b232.mp4) is a Korg nanoKONTROL 2 MIDI controller. ##Will I be banned by EAC for using MIDI convars? No.
