ncc
===
ncc compiles text-based configuration files into custom modes for Novation MIDI
devices.
The behavior and appearance of controls on the device are specified using
[TOML] files, which are then compiled by ncc into MIDI SysEx messages that can
be sent to the hardware to apply the custom mode.
[TOML]: https://toml.io
*ncc is not affiliated with Novation or its parent, Focusrite plc.*
Supported devices
-----------------
* Launchkey \[MK3]: full support
* Launchkey Mini \[MK3]: full support, tested[^1]
* FLkey: full support
* FLkey Mini: full support
* Launchpad X: full support, tested[^1]
* Launchpad Mini \[MK3]: full support
[^1]: Tested on real hardware.
Installation
------------
Ensure [Rust][rust-inst] 1.74 or later is installed. Then install with Cargo:
[rust-inst]: https://www.rust-lang.org/tools/install
```bash
cargo install ncc
```
This will install a binary named `ncc` in `~/.cargo/bin`. If that directory is
in your `PATH`, you can run the program simply by typing `ncc` in your shell:
```console
$ ncc --version
ncc 0.1.3
```
Manual installation
To compile and install ncc manually, ensure the following dependencies are
installed:
* [Rust] 1.74 or later
* [Git]
[Rust]: https://www.rust-lang.org
[Git]: https://git-scm.com
Download the source code:
```bash
git clone https://github.com/taylordotfish/ncc
cd ncc
```
Build and install the program:
```bash
cargo install --path .
```
Alternatively, you can build and run ncc locally without installing:
```console
$ cargo build --release
$ ./target/release/ncc --version
ncc 0.1.4-dev
```
Usage
-----
See `ncc --help` for detailed usage information. The simplest use of ncc is
`ncc `, which compiles the TOML file `` into a SysEx file with the
same name but ending in `.syx`:
```console
$ cd examples/launchkey-mini-mk3
$ ls example-pads*
example-pads.toml
$ ncc example-pads.toml
$ ls example-pads*
example-pads.toml example-pads.syx
```
See the [examples] directory for a demonstration of how to write custom modes
for ncc.

Installing custom modes
-----------------------
To install custom modes on your device, the compiled `.syx` file needs to be
sent to the device as MIDI (and the response from the device must be read). The
way to do this depends on your operating system. [A guide is available][alsa]
for GNU/Linux systems using ALSA.
