MainStage (software)
MainStage is a music application developed by Apple Inc. designed for use in live performance. Features. MainStage might be thought of as a companion app to Logic Pro. It works in much the same way and bears a similar user interface. The focus however, is on live use rather than features like recording and editing that are available in a DAW such as Logic. Instead of a timeline for instance, there is an editable "Workspace". This allows a user to drag out an object that acts as a software representation of a hardware controller like a button, knob  or fader and assign that to a parameter such as volume, pan or even more complex things. MainStage comes bundled with a number of sampled software instruments (such as pianos, guitars, drum kits and pads) as well as effects. These instruments can be played using a pre-recorded MIDI file or via a controller device that uses the MIDI protocol, such as a keyboard or drum pad. It can also act as a "host" and centralize any third-party virtual instruments or audio units that users might have installed on their computers. Virtual instruments that can be used with MainStage  can also be used with Logic Pro. A MainStage concert can display a patch list which displays all the patches created by a user for that concert. Each patch might have a different instrument or effect assigned to it and various parameters can be changed during a performance by cycling through the list. Other features include: Release history. The first version of MainStage was introduced on September 12, 2007, alongside Logic Studio.

There is a free iPad companion app available designed for use with Logic Pro X, MainStage 3 and GarageBand, which can act as a hardware controller for various parameters. With the release of the version 3.5 on November 12, 2020, the long-standing compatibility with OS X 10.9 or later was dropped ; MainStage is now only available for macOS Catalina, Big Sur, and Monterey.
