This will bring up a dialog box that will allow you to select a file to read. You may select any file type that Melys knows how to read. At the current time this includes MIDI files ending in .mid or .smf and MDML files ending in .mdml. It will also read compressed MDML. Compressed files can have the same .mdml ending or a .mdml.gz ending which they would have if compressed with gzip.

You can have several files open at once. The limit is the number of queues that the sequencer is configured with (currently 8). Each file appears in its own top level window. If you click and drag the notebook tab below the main area you can place several files into the same notebook window.

This will close the current file. If the file is playing it will stop.

There are currently no warnings if it has not been saved. I do not intend to add any warnings as they slow down work, instead all operations will be undo-able.

A new song is created. It will have a number of tracks pre-allocated setup with default channel and device numbers. However there are no limits to the number of tracks and you can add more, or delete all the unused ones.

The current file is saved to the file it was read in from or last written to. If there is no remembered filename (for example if it is new) then you will be prompted, just as with the Save as... menu item.

Save the current file with a specified filename. A dialog box is brought up to allow the name to be specified.

Exits Melys.

There is currently no warning if files are not saved and all unsaved changes will be lost.

Starts the current file playing. Has no effect if the file is already playing. It is (currently) possible to start another file at the same time that another is playing. This will probably be disallowed or modified in future.

The playing file is stopped temporarily. If play is later selected the song will continue from the same point that it stopped at.

The playing file is stopped. If the file is re-started it will begin playing from the beginning.

Recording starts. If the file is not already playing, then it will start to play. Incoming events are recorded on each track that has the record button pressed until Record stop or Stop is selected. Each track has an associated recording source and only events from that source are recorded to that track.

Events are merged into any existing track parts. New parts are created as necessary to hold events that occur outside of existing parts.

In the future there will be other modes for storing new events such as replacing the events that currently exist.

Recording is stopped. The song will continue playing if it has not already finished and recording can be restarted by selecting Record again.

This will close all open windows.

This menu item will only appear if Melys is built for debugging. It will show some information that may be useful in debugging Melys.
