music, programming and a cat

The first release is close

The first release is close. Besides polishing here and there Laborejo needs a Logo.
I don't want to release even an alpha version without a logo subsequently followed by a corporate identity.

Speaking of "Alpha": There is still much to do, especially in the GUI and performance-wise. But the first release will be far away from some "initial test". It is very functional and covers most styles of music.

Undress While Playing

In the last post I used "Undress while Playing" as an example for a seldom command. I must correct this:
On the contrary, I think "Undress While Playing" should be used in every piece and theoretical example. I will use a shortcut for it after all, something adequate. Enter or Space or the left mouse button.

And while you are here, lured by the nice clarinet girl: Follow the Laborejo Google+ page: https://plus.google.com/b/116744898976321238325/.

Shortcuts // Ghost In The Shell style typing

Notation Symbols are made as a placeholders for various musical events. However, there are many symbols for many events. Different music requires different symbols. On the other hand you have shortcuts, keypresses that activate menu functions ("insert Clef") or do just something obvious without a menu(Arrow Keys). Any program should use these for often used commands so that the user is spared to browse through menus and sub-menus every time he wants to insert a note.

So far so Wikipedia.

Laborejo is still in pre-alpha state and there are already hundred(s) of possible (menu commands). And remember there is no "optimal" set of shortcuts/functions. Any user and music style wants a different one. Before I tell you how awesome Laborejo is one warning: Notation is complex and so is this software. Not complicated, you just have a massive amount of options. There is a learning curve which cannot be skipped. But learning is made as easy as possible, even if you are not Stephen Hawking.

Here are the principles which lead to enlightenment.

• Navigational keys and some really obvious keys (like Escape for "No, stop! iiaaaa....!" to stay in the Anime mood) are not in menus, only in the manual and tutorials if you don't find them directly anyway.
• Everything else is in the menu and has its shortcut written directly beneath it. You COULD use your mouse for every action, but this is slow. Don't do it. Just use it for seldom commands ("Undress while Playing") and to look up shortcuts.
• For very common commands there are single-key shortcuts. Just press it. Pressing it again deletes it. That is called a Toggle. ** "," - Staccato On/Off ** "T" - Triplet On/Off
• For variants or the reverse effect the Shift key is used as modifier: ** 1) "W" - Shift Tone Up. "Shift+W" - Shift Octave Up. ** 2) "C" - Chord Symbol. "Shift+C" - Clear Chord Symbol
• For otherwise related commands we use (only) the Alt Key as modifier. Very often the Alt Key triggers the Gui-Variant of a command or offers customized options: ** "Alt+C" - Start Mass Entry of Chord Symbols ** "Alt+T" - Any tuplet (instead of only Triplets on C)

All commands follow these patterns. And more:

• Every Ctrl+Key combination is only for controlling the non-music functions, the GUI itself. Open and Save files, Switch parts of the GUI (e.g. Track Properties) on and off etc.
• The Function Keys (F1 to F12) are for anything that is used often but does not affect the music items or properties. For example F3 is PDF Preview and F5 is Start Playback.

Last but not least there are two kinds of specialties.

• Shortcut Sequences for group of commands which are used sometimes but to give each of them a seperate key would be too much: ** Voice Presets ("Voice 1 Stems Up", "Voice 2 Stems Down") are all on Alt+V, followed by a number key to indicate the voice number. The sequence for voice 2 is: Alt+V, 2.
• Session-Shortcuts or Temporary Shortcuts. Just hover your mouse over a menu command which has no shortcut and press a free key (with modifiers like Shift) and you get that Shortcut until you restart Laborejo. Nothing gets changed, nothing destroys your config file. Clean and handy. And don't worry, I'll leave some keys free exactly to use them with hover shortcuts. You want this if you expect to use a command more often for your current session (read: More than twice). You expect some Instrument Changes? Just hover-shortcut it and you don't have to browse the menu each time.

And if all this is not enough you still have the options to just use your own config and rebind every key. But I assure you my keybindings are better than anything in "Vim Style".

Next time: Modal Number Keys to insert Notes without Midi Hardware or adding Fingerings to notes - your mode, your choice.

If you hate the note C you can now replace it

New in git: search and replace. Now you can replace every occurrence of the note C in Beethovens music with a rest, assuming you hate Cs. And it is just one line of python spaghetti code with lambdas!

api.replace(lambda i, c: "<c'>" in i.exportLilypond(), lambda i: api._insertRest(i.duration*2))

Explanation: Go through the whole music and for every note which would export as lilypond "<c'>", a single note c' of any duration, delete it and replace it with a rest which is twice as long as the original notes duration.

I am not sure yet how to build this into the GUI. And of course you have to type in Beethovens music into Laborejo first :)
