Part Editor

The part editor is used to edit the contents of a part, which usually consists of MIDI notes but may also include automation, which is always sent to the instrument on the note's track.

Row Header

The row header is located on the left side of the part editor.

The row header uses a traditional keyboard representation for most instruments. However, if the note's track uses the Slate instrument, the row header will use a list representation which also indicates the instrument's pad names.

DRAG to move the view up or down.

PINCH ZOOM to change the vertical scale.

TAP to audition a note (if the note audition command button is enabled).

Time Ribbon

The time ribbon indicates the sequencer transport's current position.

The part editor's time ribbon always represents time relative to the part. In other words, it always shows the part as beginning at bar 1 even if the actual part starts on a different bar in the song itself.

TAP on the ribbon to move the sequencer's transport to the desired position.

When working on a part, you may find it useful to set the song loop so that it matches the part you're working on. You can do this quickly by DOUBLE TAPPING on the ACTIONS command button.

When enabled, the part editor will automatically scroll its view to keep the current transport position visible.

Editing Window

Use the editing window to navigate the view and make selections.

Navigation and selection can be performed with the traditional DRAG and PINCH ZOOM actions, but you will often find that the SELECT and ZOOM command buttons are a more efficient way to achieve these operations in a more task-oriented manner.


SCROLLING - Use two fingers to PINCH ZOOM, and then release one finger and drag. Alternatively, you can use the scrollbars.

ZOOMING - Use two fingers to PINCH ZOOM. You can perform a context-sensitive zoom by double tapping the ZOOM command button. Alternatively, you can use the +/- buttons on the scrollbars.

TAP or DRAG to make a selection.
You can change the selection mode via the SELECT command button.

TAP on the background to deselect all.
DOUBLE TAP on the background to select all.

Editing Notes

To move a note or a selection of notes, TAP AND HOLD on one of the notes. After a short pause you will be able to freely move the selected note(s) by dragging horizontally or vertically.

Most of the time you will just want to move notes horizontally or vertically. The best way to achieve this is with the white drag handles which appear around the edges of the view when a selection is made:

Moves the selection forwards or backwards in time.
Changes the length of the selection.
Moves the selection vertically.
Moves the selection up or down by a single row.
Moves the selection up or down by a whole octave.
Scales the velocity of the selected notes.

Note Appearance

Unselected notes are blue.

Selected notes are white.

The smaller horizontal bar within the note indicates the note's velocity.

Command Buttons

Use the command buttons to set beat grid properties, perform task-oriented zoom/selection and edit the selected region of the note.

AUDITION BUTTON. When enabled, the part editor will play a note when it's selected or edited. It will only play if the selection contains the same note.
GRID TAP to view or change the grid and snap options.

DOUBLE TAP to toggle the grid snap on or off.
ZOOM TAP to zoom on a specific area part.

DOUBLE TAP to perform a context-sensitive zoom.
DOUBLE TAP AGAIN to revert to the previous zoom.
SELECT TAP to select a specific area of the part.

DOUBLE TAP to toggle the selection mode.
DRAW TAP to enable draw mode. When draw mode is enabled you can tap or drag in the editing window to create or delete notes.

TAP AND HOLD for extra options, such as drawing multiple repeating notes at the current grid interval.
DELETE Deletes the current selection.
DUPLICATE Duplicates the current selection.

TAP AND HOLD for more options, such as making multiple duplicates.
ACTIONS Performs general editing actions on the current selection such as joining, splitting, quantizing, copying and pasting.

DOUBLE TAP to set the song loop to the entire part.
BACK TO SONG Closes the part editor and returns back to the Song Editor.

Quantizing Notes

To quantize a selection, tap on the ACTIONS command button and choose the QUANTIZE option.

The WHITE notes preview the result of the quantize operation. The RED notes are the ones which are the furthest away from the chosen quantize interval and require the most quantization. The GREEN notes are the ones closest to the quantize interval.

Use the WINDOW slider to filter out any notes which are too far away from the quantize interval.

Use the STRENGTH slider to reduce the effect of the quantization if you want to retain a more natural feel.

Editing Note Velocity

To reveal the velocity editor, tap the button highlighted in GREEN.

Navigation and selection in the velocity editor works in just the same way as editing notes.

Any selection you make in the velocity editor will also select the corresponding notes in the note editor, and vice versa.

The velocity editor has two dedicated vertical drag handles:

SCALES the velocity of the selected notes (ie. by multiplying their velocity values).
OFFSETS the velocity of the selected notes (ie. by adding to or subtracting from their velocity values).

Part Automation

Parts may optionally contain automation. Automation is essentially a sequence of values which is used to automatically vary the controls of an instrument, effect, mixer track or send during playback. Part automation can only control the instrument on the part's track. If you wish to automate the mixer's controls, insert FX or sends then you must instead use track automation.

To reveal the part automation, tap the automation button (highlighted in GREEN).

Tap on any automation parameter to open the automation editor.
