Standard MIDI File

An SMF file contains Musical Instrument Digital Interface ( MIDI ) data, which is a standard for digital music communication. It is similar to the common .MIDI file (and .MID files), storing musical performance data, such as note sequences, tempo, volume, and instrument information. However, SMF files typically contain more complex music compositions.

Musicians, producers, and composers may use the SMF format since it allows playback across various devices and platforms that support MIDI. Additionally, there are different types of SMF files, with variations for different sequencing and playback needs.

NOTE: The MIDI Manufacturers Association (MMA) develops the SMF format.

You can open SMF files with various digital audio workstations ( DAWs ) and MIDI sequencers, such as Image-Line FL Studio , Steinberg Cubase , and Ableton Live . For example, you can open an SMF file with FL Studio by selecting File → Open .

Shortcut Maker Collection

An SMF file may also be a shortcut collection created by Shortcut Maker, an Android app that allows users to create custom home screen shortcuts for apps, settings, activities, and other Android features. It contains structured data that defines the behavior and appearance of each shortcut in a saved collection, such as the shortcut’s label, icon, target activity or intent, and any custom settings the user applied. By saving shortcuts in an SMF file, users can back up their configurations or transfer them between devices and users without having to recreate everything manually.

Android power users or those who enjoy customizing their device’s home screen layout are the primary users of Shortcut Maker. When a user saves a group of shortcuts they’ve configured, the app stores them in an SMF file. Shortcut Maker and SMF files make it easier to organize access to apps and actions, especially on devices with many installed apps or complex workflows.

You can open SMF files with Shortcut Maker on an Android device. Shortcut Maker automatically loads SMF files, but if you need to restore shortcuts saved in an SMF file:

Once you restore the shortcuts from an SMF file, they will appear in your Shortcut Maker history. From there, you can review, edit, or add them to your home screen as needed.
