Hello

This website contains prototypes of some minimal applications that are currently being developed.

• notes - become fluent in recognition of musical notes.
• typing - mastery of the ASCII code.

Notes

Enter the name of the note you see: a, b, c, d, e, f, or g. To select a clef: 0 - all clefs, 1 - bass, 2 - treble.

p + Enter shows current preferences. p1 (for the bass clef) + 12 + Enter sets the the first and the second octaves for the bass clef. p24 + Enter sets the fourth octave for the treble clef. p2 + Enter resets the treble clef octaves to default. p0 + Enter resets all octaves to default.

Scientific notation is used for note names.

Typing

There is no ideal method for text input. Why not directly in ASCII codes (hex)? This is the right place to do it. You can also type characters for some Western European languages.

You don't have to press the Space Bar or Enter. 08 deletes the last character, 00 00 clears the output. Non-hexadecimal values are ignored.

For a quick start try this: 48 65 6c 6c 6f 2c 20 57 6f 72 6c 64 21. Type a capital I to focus the input field. Tip: A convenient method for entering hexadecimal values is to use the numeric keypad for the right hand; or for the left hand, if you are a rock star.

About

Fun, simplicity und usability are the focus of this web page.

It was created from scratch with vanilla HTML/CSS/JavaScript.

To avoid collisions when typing, all global keyboard commands are in upper case.
