 +====== Virtual Instruments Sequencer ======
 +Compose songs with the Virtual Instruments sequencer: from input of notes to sound generation the sequencer provides all functions. This manual explains the individual functions.\\
 +By default, the sequencer'​s demo version is included in the Aubade Audio Studio. In the full version of Aubade, however, you can unlock the full functionality of the sequencer by means of an in-app purchase.
 +
 +===== Overview =====
 +A song consists of one or more patterns. The notes of a pattern are entered via the Piano Roll Editor.\\
 +In the Playlist, the song is composed of the individual patterns.\\
 +When you leave the Virtual Instruments sequencer, the audio signal is generated on the track that you used to call the sequencer.
 +
 +
 +===== Pattern =====
 +Tap a pattern tab to open the pattern. There you see the input grid of the Piano Roll Editor, which is described below.
 +
 +==== Piano Roll Editor ====
 +=== Add a Note ===
 +You can insert a new note by tapping into the grid at the desired location.\\
 +The note is created according to the snap settings. For example, if the snap is set to 1/2 beat and you have a 4/4 beat (1 beat = 1/4 note), then an eighth note is generated, which is aligned to the eighth note grid.\\
 +The velocity of the newly created note is equal to the Default Velocity set in the main menu.
 +
 +
 +=== Move a Note ===
 +By touch & hold you can release a note from the grid, then move it. So, touch the note until its color changes to green and then move it without releasing the note. Once the note is ready to move, haptic feedback is generated (some devices do not support this function).\\
 +While moving, you will be shown which grid point the note would be placed on if you were to release it now. If the note intersects with another note in the grid, it is displayed in red and can not be placed there. If you still release it, the note jumps back to the initial position.
 +
 +=== Resize a Note ===
 +Tap a note to highlight it for editing. Around the note appear different input elements.\\
 +Use the handles on the left and right of the note to change the note length. The currently set snap raster also applies here.
 +
 +=== Edit the Velocity of a Note ===
 +Tap a note to highlight it for editing. Around the note appear different input elements.\\
 +Then tap the button with the percentage (the current velocity value is displayed here) and use the number picker to choose a new velocity value.
 +
 +=== Remove a Note ===
 +Tap a note to highlight it for editing. Around the note appear different input elements.\\
 +Tap the button with the trash can icon to remove the note.
 +
 +=== Snap ===
 +At the top right is the snap button. The snap value set there determines the grid for the notes. The length of newly set notes is determined by the current snap value, and when changing the note length, the length snaps to the raster.
 +
 +=== Chord ===
 +On the right edge of the screen, below the snap button, is the Chord button for selecting a chord. Tap the button and then select a chord from the list.\\
 +In the input grid, tap on the root note of the chord. The remaining notes of the chord are then automatically generated above the root.\\
 +However, the chord will not be created unless all required notes are free. You must clear the notes in question to create the chord.\\
 +//Note: The chord generator is only available in the full version of the Virtual Instruments Sequencer.//​
 +
 +=== Scale the Grid ===
 +With the usual two-finger gesture, you can zoom in or out of the Piano Roll Editor.
 +
 +=== Column Width ===
 +The current column width is displayed as an orientation aid at the bottom left.
 +
 +==== Preview ====
 +At the bottom right is a preview button which allows you to listen to the pattern in advance.\\
 +The preview quality is not as good as the quality of the final audio signal, because for technical reasons different instrument samples are used.
 +
 +==== Keyboard ====
 +A stylized keyboard is located to the left of the Piano Roll Editor.\\
 +The keyboard serves on the one hand as an orientation on the octave and the note within the octave; on the other hand, the note can also be played with the respective instrument by tapping on a key.\\
 +//Note: Not every instrument has the full octave range. Some keys will not produce any sound.//
 +
 +===== Playlist =====
 +In the Playlist you define the sequence of the patterns.\\
 +To be able to generate an audio signal, the playlist must contain at least one entry.
 +
 +==== Add an Entry ====

 +
 +==== Edit an Entry ====
 +Tap a list entry to edit it. You can then select a different pattern as well as change the number of repetitions.
 +
 +==== Move an Entry ====
 +With Touch & Hold, you can release an entry from the list so that it can be moved to another list position by drag & drop.
 +
 +
 +==== Remove an Entry ====
