PIANO ROLL

Piano roll Strum Tool

The Strum tool shifts the timing and velocity of the individual notes in chords to simulate strumming (simulating guitar playing for example). The tool works by treating any overlapping notes, that share the same start time, as part of the same chord. The dialog box provides modification of the relative start time, velocity and end time (see the example picture below).

1. Start section

The Start section lets you modify note start times and/or velocity. Enable this section by activating the LED in the top left corner.

• Time: Shifts the start time of chord notes to create strumming effects.
  • Start knob - Adjusts the start time offset applied to the notes. A positive shift strums from low to high notes, while a negative shift strums from high to low notes.
  • Tension knob - Adjusts the strum 'tension', i.e. acceleration. Set a positive value to accelerate the strum or a negative value to decelerate it.
• Velocity: Increase or decrease the velocity (volume) of the subsequent notes in strummed chords.
  • Start knob - Adjusts the change in velocity applied to successive notes. A positive value decreases the velocity with each note, while a negative value increases it.
  • Tension knob - Adjusts the velocity acceleration or 'tension'. Set a positive value to accelerate the velocity change with each note or a negative value to decelerate velocity.
• Preserve end - Enable this option to preserve the end time of the affected notes (note that the End section can still modify the end time) thus modifying the notes' length.

2. End section

Enable this section by activating the LED in the top left corner. The End section modifies note end time.

• Time: Shifts the end time of chord notes.
  • Start knob - Adjusts the amount of time shift applied to the end of the notes. You can also apply a negative shift.
  • Tension knob - Adjusts the strum 'tension', i.e. acceleration. Set a positive value to accelerate the effect with time, or a negative value to decelerate it.
