Maps midi signals coming from ALSA midi devices to shell commands
Build: `$ make && sudo make install`
usage: midiMap <config file>
This is a daemon program, it does not start any background process by itself and needs to be constantly running for the mapping to be active
This program is in early stage but is fully functional without any major errors
Known issues:
- Doesn't support multiple identical devices
See 'example.mim' for an example config file
To scan for devices use `$ aseqdump -l`
To scan a device's inputs use `$ aseqdump -p <client name>`

# zmidimap
Map midi signals coming from ALSA midi devices to shell commands
Soft dependencies: alsa-utils
Hard dependencies: aseqdump
## Installing
### Package
#### Debian/Ubuntu
Download the .deb package then run: `sudo dpkg -i zmidimap.deb ; sudo apt -f install`
### Standalone
Move executable `zmidimap` to your PATH directory
### From source
```sh
git clone https://github.com/zawwz/zmidimap.git
cd zmidimap
make && sudo make install
```
## Usage
`zmidimap [options] <map file>`
This is a daemon program, it does not start any background process by itself and needs to be constantly running for the mapping to be active
## Map File / Configuration
See `example.mim` for an example file
For more details see `zmidimap --help`
## Options
To scan for devices use `zmidimap -l`
To scan a device's inputs use `zmidimap -p <client name>`
For more details see `zmidimap --help`
