The Tools panel offers the following options for modifying events and notes:


Use this button and draw out a selection rectangle to select multiple events or notes. Tap this button again to deactivate it and to enable other options.


Splits selected events. The playhead's position sets the split point.


Merges selected MIDI events into one.


Deletes selected events.


Tap and hold to create a new event. Slide to the right to determine its length.


Toggles whether currently selected events are muted.


Reverts your last action(s). A small overlay panel briefly shows the action being undone.
Long-tap this button to display a list of the complete undo history. Tapping an item in this list reverts the project back to the selected point in time. Note: Cubasis saves up to 500 undo steps, which are always available, even after loading another project. Audio editor related undo steps are an exception, the amount of available undo steps depends on the file size. The redo (but not the undo) history is discarded after another project is loaded.


Redoes your last undone action(s). A small overlay panel briefly shows the action being redone.
Long-tap this button to display a list of the complete redo history. Tapping an item in this list forwards the project back to the selected point in time.


Copies selected events and notes into clipboard.

Note: Copying and splitting audio events duplicates their audio file. Therefore, editing a copied event will leave the original unchanged. However, copying events with large file sizes may result in longer processing times.


Pastes events and notes from clipboard into your project, starting at the playhead.

Transpose / Pitch Shift

Note: When time-stretching and pitch shifting an audio event at the same time, both tools must use the same algorithm.


Quantizes all selected notes (or notes within selected events). The following options are available:


Controls the dimensions of the grid which the playhead, events, event handles, notes and note lengths snap to, ranging from bars to 1/64 notes, including dotted and triplet modifiers. The chosen snap grid applies to the arranger's and the MIDI, audio and automation editor's grids.
Long-tap this button to toggle between OFF and the previously selected grid value. Note: When snap is disabled, notes and events will snap to a resolution of 960 ppqn (parts per quarter note) which is as precise as a 1/3840th note.


The time-stretch tool is available for audio and MIDI events. It affects the duration, but not the pitch. The following options are available:

Custom / imported audio files might not contain the tempo information readable by Cubasis (iXML), in which case Auto stretching leaves the event unchanged. To achieve the desired tempo syncing, follow these steps:

Limitations of time-stretch and pitch shift

Please note that the performance of real-time time-stretch and pitch shift depends on many factors such as the device model you use as well as the sample rate, the hardware latency project setting, the number of tracks and instruments and effects used in your project. In addition, using inter-app data streaming technologies such as Audiobus, Audio Unit and Inter-App Audio along with a number of assigned instrument apps has a significant impact on the performance of your device.

Depending on what device model you are using, the number of tracks that contain time-stretch or pitch shift and the complexity of your project, will sooner or later provoke performance limits.

There are several options to improve performance if you encounter performance limits with time-stretch and pitch shift:
