How to Use the Piano Roll in FL Studio

The Piano Roll is where most of the actual music happens in FL Studio. Learning how to use the Piano Roll in FL Studio means getting comfortable drawing notes, editing their length and velocity, using snapping to stay in time, and reaching for the built-in tools that speed up melody and chord writing. This guide covers everything you need to start writing parts confidently.

Opening the Piano Roll

Every channel in the Channel Rack has its own Piano Roll. Right-click the channel name and choose Piano roll, or click the keyboard icon. Notes you draw here play through that channel’s instrument, so load your sound first — if it’s a third-party synth, see how to add VST plugins in FL Studio.

Drawing and editing notes

The Piano Roll uses the same tool set as the rest of FL Studio, found in the top-left toolbar:

• Draw (pencil): click to place a note. Drag its right edge to change length.
• Paint (brush): click and drag to lay down a run of repeated notes quickly.
• Delete: right-click any note to remove it.
• Slice: cut notes into shorter pieces.
• Select: drag a box to grab multiple notes, then move, copy or transpose them together.

Hold and drag a note to move it in pitch and time. To shift a whole selection up or down by octaves, select the notes and use the shift-and-arrow shortcuts.

Snapping and timing

The snap control (top toolbar, often shown as a magnet) decides where notes land. Set it to a beat or step value to keep everything in time, or switch to none when you want to nudge notes slightly off-grid for a human feel. Getting timing right here is the foundation of a tight groove, which matters as much as good gain staging later in the chain.

Velocity and expression

At the bottom of the Piano Roll is the event editor. Switch it to velocity to set how hard each note plays — varied velocity is the single biggest thing that makes programmed parts sound alive. You can also edit pan, pitch and other properties per note here, which is great for slides and pitch bends on basslines.

Time-saving tools

The Piano Roll’s Tools menu (the wrench, sometimes under a stamp/arrow menu) is packed with helpers:

• Chords and scales: stamp full chords from a menu, or highlight a scale so out-of-key notes are dimmed.
• Arpeggiate: turn a chord into a rolling arpeggio pattern.
• Strum: offset chord notes slightly for a guitar-like strum.
• Riff machine and randomise: generate ideas when you’re stuck.

You can also enable ghost notes so notes from other channels appear faded in the background, making it easy to write a bassline against your chords.

Frequently asked questions

How do I make notes stay in key in the Piano Roll?

Use the scale highlighting in the Tools menu to mark your key — out-of-scale notes are dimmed so they’re easy to avoid. You can also use the chord and scale stamps to place correct notes directly.

How do I change note velocity in FL Studio?

Open the event editor at the bottom of the Piano Roll and set it to velocity. Each note has a bar you can drag up or down. Varying velocity adds dynamics and makes programmed parts feel more natural.

What are ghost notes in the Piano Roll?

Ghost notes are faded notes from other channels shown in the background of the current channel’s Piano Roll. They help you line up parts — for example, writing a melody that fits chords you wrote on another channel.
