SONG RECORDING

Entering Velocity Curves

In Step recording, all notes are recorded at the same velocity or volume. To make a Step-recorded track sound more natural or to create some dynamic changes in the track, use the Velocity Curve function.

1)Select the first note to be affected by the Velocity Curve (by using the +/- buttons of the numeric keypad). All subsequent notes will be velocity-transformed.

2)Simultaneously hold down the VELOCITY button (“0” in the numeric keypad) and press + or - to select the desired Velocity Curve.

MEASURE 001-201

Selected Velocity Curve appears as icon in the display.

3)At the “Change?” prompt,

press the + button (“YES”) to actually enter the selected Veloc- ity Curve, or press the - button to cancel the operation.

Velocity Curve Chart

Display Type/Description

Mezzoforte

This sets all subsequent notes to a velocity value of 80.

Forte

This sets all subsequent notes to a velocity value of 100.

Fortissimo

This sets all subsequent notes to a velocity value of 120.

Mezzopiano

This sets all subsequent notes to a velocity value of 60.

Piano

This sets all subsequent notes to a velocity value of 40.

Pianissimo

This sets all subsequent notes to a velocity value of 20.

Crescendo 1

This creates a two-measure crescendo, starting with the current velocity at the selected note and ending with a velocity increase of 40.

Crescendo 2

This creates a two-measure crescendo, starting with the current velocity at the selected note and ending with a velocity increase of 20.

Crescendo 3

This creates a two-measure crescendo, starting with the current velocity at the selected note and ending with a velocity increase of 10.

You can specify a Velocity Curve in the middle of a track BEFORE recording the notes that the curve will affect. To do this, select the last note of the track (by using the +/- buttons), then enter the desired Velocity Curve. In this case, the Velocity Curve is NOT applied to that last note, but affects all subsequently entered notes.

Display Type/Description

Diminuendo 1

This creates a two-measure diminuendo, starting with the current velocity at the selected note and ending with a velocity decrease of 40.

Diminuendo 2

This creates a two-measure diminuendo, starting with the current velocity at the selected note and ending with a velocity decrease of 20.

Diminuendo 3

This creates a two-measure diminuendo, starting with the current velocity at the selected note and ending with a velocity decrease of 10.

Accent 1

This increases the velocity of notes at the top (1st beat) of all measures by 30. (Display icon represents two measures.)

Accent 2

This increases the velocity of notes at the top and halfway points of all measures by 30. (Display icon represents two measures.)

Triangle wave

This alternately and gradually increases and decreases the velocity by 30 in the pattern of a triangle wave. The wave repeats every two measures throughout the track. (Display icon represents two measures.)

Square wave

This alternately and abruptly increases and decreases the velocity by 30 in the pattern of a square wave. The wave repeats every two measures throughout the track. (Display icon 89 represents two measures.)
