Building from source​

  2. Run dotnet build in the Akorin folder

Currently supported reclist formats are plain text and ARL. You can check Projects to see what other formats are planned.

Writing an Akorin Recording List​

Akorin Recording Lists use YAML, which is very simple to read and write. Create a plain text file using a text editor like Notepad or TextEdit, with the following formatting.
line 1: note 1
line 2: note 2
line 3: note 3
Save the file with the extension .arl. You can refer to the reclists included in the releases for examples of a full reclist. If Akorin has trouble reading the reclist, try surrounding the line or note with double quotes "like this".
