This is a basic nine-instrument keyboard. It lacks a lot of features and isn't really cut out for much, but I had fun making it. Instrument controls: Click on an instrument to select it. Multiple instruments can be selected. Press space to deselect all instruments. Octave controls: To adjust the octave, use the on-screen arrows, the up and down arrow keys, or the on-screen octave button. Setting the octave to a decimal allows for key changes. Note controls: Use your keyboard to create notes. A major scale can be played with the home row; sharps and flats are found on the row above. The pattern for a major scale is: asdfghjk and for minor: asefgyuk Sustain controls: Adjust the length of the note using the on-screen arrows and buttons or the left and right arrow keys. Tempo controls: Use the on-screen arrows and buttons to adjust the tempo, or the Z and X keys. Click the 'beat' button for a metronome.
