PIANO ROLL

Piano Roll Strum Tool

The Strum tool lets you shift the timing and velocity of the individual notes in chords to simulate strumming (as in guitar playing and some other string instruments).

Any set of partially or fully overlapping notes which share the same start time are considered a chord. The dialog box lets you set three kinds of modification to the chords: start time shifting, velocity shifting, and end time shifting.

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 at its top left corner. The End section lets you modify notes' end time.

Time:

Lets you shift 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.
