Tools

The Key Editor uses most of the same tools as the arranger; Select and Draw are its main modes.

Select Functions	Draw Functions
Select / deselect note: Tap the note Select multiple notes: Tap-hold and drag out a band-box or tap more notes to add them to the selection Select all notes: Double tap Deselect all notes: Tap in an empty space Move notes: Select, then drag the notes Adjust length: Drag the arrow icon to the right of the note	Add note: Tap Delete note: Tap the note Adjust length: Hold after creating a note and move the finger horizontally or use the arrow icon on existing notes Move note: Drag a selected note (tapping will delete it) Draw velocities: Slide your finger accross the velocity field; any velocity value will be overwritten

All tools explained:

Select: To select a single note, tap it. To select multiple notes, tap and hold an empty space, then drag out a rectangle touching the notes you want to select. Move selected notes by dragging them. Note: Double tap inside the Key Editor to select all notes. Tap in an empty space to deselect all notes.
Split: Splits selected notes in two. The playhead's position sets the split point.
Erase: Deletes all selected notes.
Draw: Using this tool and tapping anywhere on the Key Editor's view will place a note. Hold after placing it to adjust its length. Tapping a note deletes it. Also, draw lets you quickly draw out your note's velocities in one go. Slide your finger across the velocity field and the bars instantly adapt the drawn values.
Undo: Reverts your last action(s). A small overlay panel briefly shows the action being redone.
Redo: Repeats the step(s) you've previously undone. A small overlay panel briefly shows the action being redone.
Copy: Copies selected notes into clipboard. These can be inserted into any MIDI event.
Paste: Pastes notes from clipboard into your event, starting at the playhead's position.
Transpose: Transposes notes on a semitone and octave scale.
Quantize: Quantizes all selected notes. The button to its right brings up quantization options.
Snap: Specifices the dimensions of the grid which notes, note lenghts (and the playhead) snap to (ranging from bars to 1/64 notes).

The MIDI editor provides 6 additional editing utilities for notes:

Lock: Disables view movement and zoom. When editing a specific part only, this prevents accidental scrolling.
Velocity: Adjust the velocity of selected notes by swiping upwards / downwards.
Transpose: Selected notes can only be moved vertically.
Move: Selected notes can only be moved horizontally.
Length: Selected notes can be changed in length.
Preview: Turn preview on to play back selected, triggered or moved notes.

Apart from the preview and lock buttons, the above tools are only active while being touched. Tap and hold them while swiping anywhere within the Key Editor with another finger to use them.

Rename

Tap the event's name in the top left corner of the Key Editor to bring up the rename dialog.

Parameters

The parameter field of the Key Editor controls MIDI parameters, which can be automated to change in value during playback. To open parameter editing, tap the field, which will enlarge it and display a list with all available parameters.

Parameters with existing data are highlighted and marked with a " * ". Select a parameter from the list on the left to view and edit it.

To input or edit data for a parameter, use Select / Draw / Erase from the tools menu. The density of automation points will correspond to the selected grid size.
Once you're done editing, tap the upper note area.

Consider the following when customizing your parameters:

Micro Sonic only reacts to the parameters velocity, pitch bend and sustain (CC64).
Micrologue only reacts to the parameters velocity, pitch bend, sustain (CC64) and modulation (CC1).
Aftertouch, program change and other CC parameters can be configured for MIDI output and Inter-App Audio but are ignored by Cubasis' internal instruments.

The following parameters are available:

Velocity
Pitch bend
Aftertouch
Program change
CC 64 Sustain
CC 0 Bank select
CC 1 Modulation
CC 2 Breath
CC 3 - 6
CC 7 Volume
CC 8 Balance
CC 9
CC 10 Pan
CC 11 Expression
CC 12 - 119
CC 120 All sound off
CC 121 Reset controls
CC 122 Local controll
