The main window is divided into five primary areas or "views."  They work together to provide you with a display of information you're most likely to require during a live performance.  Here's what MIDI Maestro might look like after loading a set (a play list).

At the top of the window is title of the set and/or song that's currently opened.  To the right are the pull-down menus.  Under these is the toolbar.

The first two toolbar icons set either "edit" mode (the mouse) or "perform" mode (the keyboard).  All editing is locked-out in perform mode to prevent accidental changes.  Next is the "reset" icon (lightning bolt).  The icons to follow are standard editing functions such as new, open, save, cut, paste, undo, and redo.  The remainder of the icons are used to edit and draw in views such as the Staff View.

On the left-hand side of the window is the Songs & Markers view.

The Songs & Markers view is a "tree."  Branches of the tree may be opened or closed by clicking on the "+" and "-" symbols.  Songs may be grouped into folders, and markers (and other cues with text) are shown below each song.  Double-click a song to open it, or double-click a marker to jump immediately to a specific song position. The list may be "minimized" by clicking the arrow button in the bar at the top of the list.  The list may be made a a top-level (desktop) window by right-clicking in the list and selecting that command.  Other functions such as sorting are available from that menu as well.

To the right of  the Songs & Markers view is the Track View (a spreadsheet-like list of the tracks that make up a song), and then the Clips View, where groups of MIDI events are represented as rectangles.

Tracks are typically used to represent a particular instrument and/or a particular player.  A song may have as many as 250 tracks, each with its own row and number in the Track View.  Click on a "cell" to place the cursor, then use the arrow keys on your keyboard to move the cursor.  Select a track by clicking on its number.  Multiple tracks may be selected by holding the Control key as you click.

The Track View may be opened as a top-level (desktop) window by right-clicking in the view and selecting that command.  Other track-specific functions are available from that menu as well.

Beneath the Songs & Markers and Track Views is the transport display or Metronome View.

The Metronome View conveys a great deal of vital information.  When conducting or performing along with a sequencer, you need to keep the beat.  MIDI Maestro prominently displays the beat number, further emphasizing beat 1 with the color red.  And to further enhance your anticipation of the beat, a "bouncing ball" is used which accelerates to the bounce and slows near the top.

To the left of the beat number is the measure number.  Beneath the beat number is the tempo in "bpm," which is always the standard quarter notes per minute (regardless of the time signature).  The actual tempo is affected by a "tempo multiplier" factor (the default is 1.000).  A number of commands affect this value, such as the tempo commands on the Adjust menu and the Setup/Options/Conductor feature.

To the right of the Metronome View is the Tempo View.

The Tempo View graphically represents the tempo "map."  You can anticipate tempo changes with a glance.  Nodes may be selected and dragged using the mouse.  New nodes and slopes may be drawn using the pencil tool.

What other views are available?

There are a number of additional views used for editing and performance.  The Clips View window may actually become one of seven as follows:

The Tempo View window may host one of several views as well.  These are as follows:

First, I play in a rock band and was looking for a nice Midi
sequencer that can be use to play live jam/gig and also have FULL
control over the midi. Having a Start button, with TAP for tempo, and
also playing the introduction until I decide to start the song was a
most. Other sequencer I found did'nt give you the control like
MidiMaestro does.--Steve Hollingsworth
