Once you have started Ardour, the Session Setup window shows up.
You can click on New Session to create a brand new session, or you can open an existing session using the Other Sessions options. For now let’s create a fresh session, so click on New Session. The window should now look like the screenshot below.
Name your new project and click Open .
Avoid using any characters other than letters and numbers when naming your session. Avoid white spaces, accented letters, !@#$%*()+, periods, commas, etc. Use dashes or underscores if you like. For example, instead of “My Great Session!”, prefer “My_Great_Session”, or “MyGreatSession”, or “my-great-session”. Instead of “Açaí”, write “Acai” (without accented letters), etc. Once you have created your Ardour session, do not manually rename any folders or files that belong to the Session.
