Editing

Each Track has an editor that can be opened using the Edit button located on the right hand side of the Track. MIDI tracks are capable of editing individual events when viewed as Pianoroll, Notation or Drum (see MIDI Event Editing). The Controller Editor can be used to edit MIDI controllers like Volume or Sustain. The Tempo Editor affects the tempo of MIDI Tracks. The Multi Track Editor can edit multiple Tracks simultaneously.

Editing is not possible while the Transport is running.

All editors feature a "needle" which indicates the current Transport position (it's position equals the value of the Transport Control's Position Indicator). The gray square at the top of the needle can be moved using the mouse.
At the top of every editor is a Time Bar that shows either seconds or bars (can be changed using the Editing Menu). Clicking this bar will move the needle to the corresponding position and the Transport Control's Position Indicator will be updated accordingly. Clicking while keeping the Shift key down will scroll the editor horizontally, so the needle appears at the mouse pointer. In this case the Transport position remains unchanged. Dragging the needle while keeping the Shift key down has the same effect.
Moving the data in the editors while keeping the Transport position can be done using keyboard shortcuts as well. You can use the Shift key in combination with the Home, Cursor Left, Cursor Right or End key.

Selecting a part

A part can be selected by left-clicking the Editor's display and dragging the mouse while keeping the mouse button down. The selection can be resized by dragging its beginning or end. The editor will scroll horizontally automatically if the mouse approaches the left or right side of the editor.

Selecting on-the-fly is possible as well: click on the Editor's display while the Transport is running and keep the mouse button down until you hear the end of the part you want to select. In this case it doesn't matter where you click but when you click.

Common Editor features

Track Editors feature the following buttons:

Edit: Shows an Edit Control window. Using this window volume changes, fades etc. can be applied to the selected part. Edit Controls can have different features on different editors.
Undo: Undo edit.
Redo: Redo an edit that was undone previously.
Cut: Copies the selected part to the clipboard and then deletes the selected part.
Copy: Copies the selected part to the clipboard.
Paste: Paste from the clipboard to the editor. The data on the clipboard will be placed in the track, starting at the beginning of the selected part. The length of the selected part will be adjusted to make the clipboard data fit.
Merge: Works like Paste, but existing data is not deleted.
Repeat: Repeats the selected part a number of times.
Delete: Deletes the selected part.
Sel. All: Selects the whole track.

Export: Save the selected part to a new file. This option can be used if you need to "top and tail" a file.

All editors have a popup menu with these options:

Find Selected Part: Adjusts the Transport position so the selected part becomes visible.
Select Left: Select left hand part.
Select Right: Select right hand part.
Unselect

Most editors can be operated using the standard Windows keyboard shortcuts. A Track editor can only be used using keyboard shortcuts if only one Track editor is opened. The Time Signature and Tempo editors do not support keyboard shortcuts.
The following shortcuts are supported:

Ctrl Z: Undo
Shift Ctrl Z: Redo
Ctrl X: Cut
Ctrl C: Copy
Ctrl V: Paste
Delete: Delete
Ctrl A: Select All

Tweakable Edits

MultitrackStudio features 'tweakable edits', which means that after performing an edit (for instance pasting some audio) you can tweak the edit (for instance adjust volume, adjust position and length of the pasted part, or even add effects). Every time you make an adjustment the initial edit will be completely redone, thus ensuring optimal sound quality. Note that Undo will undo the whole (initial) edit, not the last tweak only. An edit is tweakable as long as the selected part is surrounded by a dotted line. Audio edits are non-destructive. MIDI edits are not, but MIDI files are small enough to be backed-up.

Moving audio or MIDI between Tracks.

Data can be copied to another Track by dragging and dropping, or by using the clipboard functions. In either case MultitrackStudio automatically converts between mono and stereo audio if necessary. MIDI is converted to audio and vice versa automatically as well. Audio to MIDI conversion works with monophonic (ie. just one note sounds at a time) audio only. The reliability of the note recognition process depends on the audio signal. Usually some editing will be necessary to fix some errors.
MIDI to audio conversion makes use of a Softsynth. This Softsynth appears on the Edit Control window of the receiving track.

Using an editor's Cut, Copy and Paste options you can move or copy a part to this or another editor. This process uses the Clipboard. MultitrackStudio doesn't use the Windows clipboard, but a file in the Windows temporary folder instead.

Audio and MIDI files can be dragged from Windows Explorer to a Track's editor.

The Editing Menu

The Editing menu contains several options concerning editing. Most of them are available on the Edit Control as well.

Edit Control

The Editing Menu contains the following items:

Gridsnap: Turning on Gridsnap makes the start and end point of all currently selected parts snap to the (visible) grid. All subsequent the mouse movements will snap to the grid as well. Use the Zoom In and Zoom Out functions to change the grid.
Insert: When active pasted (or drag-and-dropped) parts will be inserted. Existing data will be overwritten otherwise. Insert will usually be off in order to avoid misaligned tracks.
Time Scale Seconds: Grid in seconds.
Time Scale Bars: Grid in bars. Also, MIDI paste and drag operations will be done in beats instead of seconds (e.g., If you move a slow part to a fast part it will be made faster).
Time Scale Automatic: When this option is active the grid will automatically be set to bars when a MIDI file is loaded. If there is no MIDI Track the grid is set to seconds.
Zoom In/Out: Use the Zoom In and Zoom Out functions to change the horizontal scale of the editors (all editors have the same time scale). The current scale is displayed on the Status Bar. Scale 1:1 means that one screen pixel is used for every audio sample. Zooming out will put more samples on a pixel.
Tempo: Shows the Tempo/Time Signature Editor. This option is available only if there is at least one MIDI Track.
Multi Track Editor: shows the Multi Track Editor.
