Zooming in MIDI Editors
The MIDI editors provide several zooming options:
The zoom sliders.
The Zoom tool.
The Zoom submenu in the Edit menu.
When you use the Zoom tool for zooming, you can determine if you want to zoom horizontal only or horizontal and vertical at a time.
To activate/deactivate the corresponding option, activate/deactivate Zoom Tool Standard Mode: Horizontal Zooming Only in the Preferences dialog (Editing—Tools page).
