Processing : Event Operations : Step Input Command : Step Input Controls

Step Input Controls
The Step Input page has the following controls:
Enable
When selected, adds MIDI events to the destination track when you play your external MIDI keyboard. Additionally, each previously record-enabled MIDI track is taken out of record enable.
If a Default Thru Instrument is defined in the MIDI Preferences page, it is disabled when Step Input is enabled, and is re-enabled when Step Input is no longer disabled.
Destination
Lets you select the destination track for the Step Input from a pop-up list of all the MIDI tracks in your session.
Step Increment Section Controls
The controls in the Step Increment section let you set the spacing and duration of MIDI events entered using the Step Input operation. You can select any size from whole notes to sixty-fourth notes (including dotted values).
Tuplet
Lets you input irregular note groupings (such as triplets or quintuplets). The tuplet length is calculated from the note spacing selection and the Tuplet values. For example, an eighth note equals 480 ticks, so tuplet eighth notes with 3 in time of 2 would yield a note spacing of 320 ticks (480 ticks / 3 * 2).
Note Length
Lets you select the note length as a percentage of the spacing value. For example, an eighth note equals 480 ticks, so an eighth note with an 80% duration would be 384 ticks long.
Step Input Options
Use Input Velocity
When selected, MIDI notes are recorded using the velocity that you play on your MIDI keyboard.
Set Velocity To
When selected, MIDI notes are recorded with the velocity that you specify in the Velocity field. This value can be set with the Velocity slider.
Enable Numeric Keypad Shortcuts
When selected, Step Input options can be selected from the numeric keypad. See Numeric Keypad Shortcuts for Step Input.
Undo Step, Next Step, and Redo Step
Use the Undo Step and Next Step buttons to do the following:
*   
Move the step insertion point, by either removing the previous note or by advancing the insertion point by the Step Increment value.
*   
Lengthen and shorten notes that are being held on the MIDI controller, by adding or removing Step Increment values. The Step Increment value can be changed mid-note to create a note with a hybrid note length.
Use the Redo Step button to sequentially redo any previously undone steps.
Undo Step
When the previous note has been released from the MIDI keyboard, and the insertion point has moved forward to the next note, Undo Step removes the entire last note.
When a note is being held on the MIDI keyboard, Undo Step changes to read “Decrement,” and removes the last Step Increment length that was added to the held note.
Next Step (or Increment)
When no note is being held on the MIDI keyboard, Next Step moves the insertion point by the Step Increment value, essentially inserting a musical rest.
When a note is being held on the MIDI keyboard, Next Step changes to read “Increment” and adds the Step Increment value to the held note, increasing its length by the Step Increment value.
While the note is being held, the Step Increment value can be changed, allowing you to create notes of any musical length.
Redo Step
Reinserts the last note that was removed by the Undo Step operation.
