Piano roll

FL Studio's Piano roll has the well deserved reputation as the best Piano roll in the business. The Piano roll sends note and automation data to plugin instruments associated with the Piano roll's Channel. This process is known as 'sequencing'. There are a number of useful tools to help with complex score editing and other manipulations as described below. Note pitch is displayed on the vertical axis and time on the horizontal axis. This is the exact principle as paper 'Piano rolls' used to automate player-pianos in former times. The resolution of the grid is user-selectable (zoomable) and allows the composition of songs with unlimited complexity. Note data can be entered manually with the editing tools or recorded in from 'live' MIDI controllers, then edited to fix mistakes or make changes.

Piano roll Basics

  • Notes - are displayed as horizontal bars. Slides are shown as horizontal bars with a small triangle drawn in the right side. Preview Channels by Left-clicking the Preview Keyboard keys.
  • Pitch - is mapped from bottom (low) to top (high).
  • Duration - The horizontal length represents time. The number on the Piano roll's top-ruler are bars (groups of beats).
  • Resolution / grid - The smaller grid each bar is divided into are set by the window's snap () setting. Resolution can also change with Zoom when Snap is set to Line. Selecting Main will use the Global Snap value. Some Global snap settings will also quantize live input recording from a MIDI controller.
  • Target Channel - Select a Channel with the drop-down menu, in the title bar, to select for editing. Channels with notes, in the currently selected Pattern, will display a tick. You can roll your mouse-wheel while hovering over the control to show Channels with notes OR hold (Ctrl+Mouse-wheel) to show used and unused Channels.

    • Portamento Toggle ( O) - When selected, notes added to the Piano roll will display a 'portamento flag' ( icon). The portamento flag causes a short slide in pitch from the end of one note to the note with the portamento flag. This is a note transition effect. NOTES: 1. these features only work with native FL Studio instruments and not VST instruments. 2. Click-and-hold functions in piano roll - Click and hold when adding a note to cycle through slide, portamento note mode. See General Options settings.
    • Slide Toggle ( S) - When selected, notes added to the Piano roll become 'slide notes' displaying the slide icon () that causes notes, above or below the slide-note, to slide to the pitch of the slide-note. The slide-time is set by the length of the slide-note.
  • Note color / Color group selector - Create note groups for independent editing of overlapping notes categorized by color group. NOTES:
    • MIDI Control - Color groups appear to plugins as separate MIDI channels, so one Piano roll can control several MIDI channels in the associated plugin.

Using the Piano roll

FL Studio has, arguably, the most powerful Piano roll editor available. Combined with the Piano roll menu you will find the possibilities are endless and (after practice) effortless.

NOTE: Many of the movement and draw commands are constrained by the snap setting that controls how notes move relative to the Piano roll grid. Hold the (Alt) key to temporarily bypass snap. Important also, the Global snap setting can be used for MIDI input quantizing.

  • Tools Menu - () is a shortcut to the Piano roll tools submenu (see the Piano roll menu page, ), containing various commands for operating on patterns in the Playlist.
  • Adding Notes - draw mode () allows you to draw, edit and delete notes. To add notes and draw the length, hold the (Left-Shift) Left-click and drag to the desired length. The paint mode () is similar, but allows you to draw multiple notes at once while dragging horizontally in the Piano roll. Notes are added monophonically (replacing any notes they overlap). Hold (Shift) to bypass monophonic paint mode. In draw or paint mode, Left-click in the Piano roll's grid to draw a note. The default length for notes will be equal to the last touched note.
  • Deleting notes - Right-Click a note to erase it (alternatively switch to erase mode to erase with Left-clicks ().
  • Selecting/Deselecting groups of notes - There are a number of methods to select several notes, so you can move and resize them all at once:
    • Standard selection - Press and hold (Ctrl key) and either click a note to select it, or drag a rectangle to select all notes in enclosed area.
    • Magic lasso - The Piano roll Menu > Select > Magic lasso option must be selected. Move your mouse pointer in a loop that encloses the notes you want to select (no clicking required, it's 'magic' remember). Make sure you have no notes selected before you perform the lasso action (Right-Click the empty Piano roll to deselect all notes and make another selection).
    • Add notes to selection - Hold (Ctrl+Shift) together while selecting to add notes to the existing selection.
    • Selecting notes in a time or pitch range - Time, (Ctrl+Left-click) or double-click the time ruler (along the top of the Piano roll) and drag along it to select all notes in a specified time range. Pitch, (Ctrl+Left-click) the Preview Keyboard to select a range of notes with the same pitch (dragging vertically on the Keyboard will select notes in the vertical pitch range).
    • Deselect all notes - While holding (Ctrl key), click empty space in Piano roll's grid.
    • Remove notes from selection - (Ctrl+Shift) deselects individual notes from the existing selection of notes.
    • Invert selection - Use (Shift+I).
    • Select mode button - Instead of holding (Ctrl key), you can also switch Piano roll to select mode by clicking the select mode button ().
  • Group notes - (Shift+G) - Group the selected notes. Grouping functions so that an action on any note in the Group will affect all other notes in the same way. Any number of groupings may be created. To group notes: make a selection using the Select tool, then use the Group function. Activate / deactivate grouping: Use the Note / Pattern Grouping switch on the Toobar icons. Deselecting the Note / Pattern Grouping switch will disable note grouping behavior until the switch is reactivated.
  • Copy & Paste - Make a selection (see above), hold the (Shift) button THEN drag selection with the left-mouse button OR (Ctrl+C), scroll to the new position/pattern and (Ctrl+V).
  • Duplicate selection - Make a selection and press (Ctrl+B). The selection, or all notes if nothing is selected, will be duplicated to the right of the original selection. To define a specific repeat interval, make a time-line equal to the complete interval to be duplicated and press (Ctrl+B). NOTE: The time-line selection and note selection can be made independently. The repeat interval is set by the time-line selection, the notes duplicated by the note selection. In this way, notes outside the time-line selection can be duplicated according to the time-line interval.
  • Moving notes - Select the note/sequence, Left-click on the note and drag vertically or horizontally. NOTES:
    • The snap setting will affect the movement.
    • Horizontal note positions can be adjusted by (Shift + mouse-wheel) by holding the cursor over a target note in the Piano roll.
    • (Shift) - Vertical position lock.
    • (Ctrl) - Horizontal position lock.
  • Bumping notes - This allows you to move the note/s by either 'snap' or 'pixel' based units. Snap units: Select the sequence/note and hold the ( Shift key) and use the arrow keys on your keyboard. The snap setting will affect the bump size. Pixel units: Hold the (Alt) key and use the arrow keys on your keyboard. In this case the zoom setting will affect the bump size.
  • Change note length - Select the note/sequence, Left-click on the right side and drag horizontally to change the note length. This can also be performed on a selection of notes. NOTE: The snap setting will affect the way in which the note changes length. If (Caps Lock) is on and the note is selected by the left side, resizing notes will anchor the note end point, moving only the start position. If the note is selected by the right side the start point will be anchored.
  • Edit Ghost notes - Use (Double Right-Click or X1 button) on the Ghost notes to switch to the Ghost channel.
  • Stretch / compress scores - Select a group of notes and drag the pop-up handle OR hold (Right-Shift) and drag the right edge of a note in the selection. This changes both note length and sequence duration. (Alt + Right-Shift) will stretch in 25% increments.
  • Slice Tool - () allows you to split one or more notes in the direction of the cut through the Piano roll. To use the cut tool, make sure you're in cut mode (the Cut button is selected), Left-click in the grid area and drag to define the "cut line" direction and length. Release the mouse button to split all notes at their intersection point with the cut line.
  • Resize chords & splits - Hold (Left-Shift) click and drag on the slice point or right-side of the chord.
  • Playback/Scrub tool - () enables you to preview the current sequence by dragging horizontally in the Piano roll (thus enabling you to define the playback speed and order). Alternatively, hold (Alt) + Right-Click while in draw mode.
  • Play notes straddling the playback position marker - When stopping and starting you can play notes that cross the playback position by opening the Audio Options and selecting 'Play truncated notes'.
  • Quick chords - Enter chords with one click using the Piano roll Menu > Tools > Stamp Tool . The stamp tool allows you to add chords & note-patterns selected from a menu.
  • Note properties - Note velocity, panning, filter-cutoff, etc, are available from the Target control menu and appear in the Piano roll Event Editor. Note properties can be adjusted by mouse-wheel (Alt+mouse-wheel) by holding the cursor over a target note in the 'Note event window'.
  • Merging scores across Patterns - Place the Pattern Clips in the Playlist, with the Pattern Clip you want to receive the other scores at the top. Select all the clips to merge then use the Edit > Merge pattern Clips function from the Playlist Menu. This merges the selected Pattern Clips into the uppermost Clip.
  • Click-and-hold functions in piano roll - Copy: Hold on an existing note. Slide & Porta: Click and hold when adding a note to cycle through slide, portamento event mode. See General Options settings.

Selection Stretch Handle

After making a selection the Stretch Handle appears. You can click and drag this to stretch the selected notes. Hold the (Alt) key to apply snap settings. Alternatively, hold (Right-Shift) key then click on the right-side of a note in the group and drag.

Mouse Wheel Property Note Changes

Hold your mouse over the note and hold (Alt+Mouse Wheel) to change the currently selected note property. To see the property being adjusted maximize the vertical zoom.

Note Properties & Event Editor

The note properties editor gives you access to a number of per-note properties and event data velocity, pan, release, Mod X & Y (where supported), pitch etc. Select the data to be edited with the Target control, as shown below.

  • Selecting Targets - Left-click to select from the menu. You can also roll your mouse-wheel while hovering over the selector.
  • Note properties - are displayed as vertical lines with a small circle at the top. The right-facing tail allows you to see the independent values of notes with the same start time. Note properties move with the notes they belong to. The editor can also display standard Event Automation associated with the pattern. NOTE: To edit the properties of a note when it has the same start time as others, make a selection first, then edit the property for the note (as shown above in red).
  • Note events - When editing Automation Events the editor works in the same way as the Event Editor.

Time Signatures

The default Project Time signature is set in the 'Project General Settings > Time settings > Set as time signature'. You can also set custom and even multiple Time Signatures per Pattern. And, since Patterns exist independent of the Playlist Time Signature, you can use multiple Time Signatures at any point in the Playlist (polyrhythms) by stacking Patterns using different Time Signatures. This flexibility means you need to manage your Pattern and Playlist time signatures independently.

NOTE: Time Signatures are a visual helper for the Piano roll and Playlist grids. They have no technical effect on the notes played, except for the downbeat heard when using the Metronome. You can safely change Time Signatures for the Pattern without affecting the notes, only the grid behind them changes. One Channel affects all - As Time Signatures are set per-Pattern, changing the Time Signature for any Piano roll (Channel) will affect ALL Channels in the Pattern. Use the Pattern Clip menu opton 'Make unique' to avoid this, if it is a problem.

TIPS: Here are some useful tips for working with Time Signatures. This applies both to the Piano roll and Playlist.

  • Set a custom Time Signature - Place the Play head at the point you want to set the new time signature and hold (Shift+Alt+T) to open the Time Signature tool.
  • Set a Time Signature range - Make a time selection and hold (Shift+Alt+T) to open the Time Signature tool. The Time Signature will return to the Project Default at the end of the selection.
  • Set a Time Signature based on the Pattern Clip location in the Playlist - Open the Clip Menu and select 'Use current time signature'
  • Move Time Signatures - Drag the Time Marker/s. Additionally you can use this feature to set partial bars of a given Time Signature.
  • More on Time Signatures - See: Playlist Time Signatures & Project General Settings.

Waveform Helper View

Sometimes it is useful to closely align notes with an audio waveform. For example when using Fruity Vocoder or Pitcher. To show the waveform drag from a waveform preview and drop on the Piano roll. To deselect this view use Piano roll menu > Helpers > Background waveform (Alt+N).

Understanding Slides & Portamento

The following ONLY applies to native FL Studio instruments. To slide a VST instrument automate the channel pitch knob. The Piano roll can slide notes from one pitch to another using slide notes above or below the notes to be affected. Slide notes have a small triangle drawn at the start of the note.

  • Add a slide note - Click the slide switch and then click as normal to add a note to the Piano roll.
  • De-select the slide mode - Click the slide button again.

NOTE: The General settings Click-and-hold & special gesture functions activate cycle slide/porta. Click and hold when adding a note to cycle through slide & porta event modes.

How slide notes work

When the slide note is reached the pitch of any overlapping notes will start sliding toward the slide note, reaching the same pitch at the end of the slide note event. The length of the slide note controls the duration of the slide. Chords - If notes are overlapping so they form part of a chord, the topmost note is used as the reference for the pitch offset (see picture below). The chord slides so the topmost note reaches the same pitch as the slide note. After the slide event ends, notes still remain offset from their original pitch.

NOTE: Slide events have all the usual note properties (velocity, panning, cutoff and resonance, etc). During slides all note properties move toward those set in the slide note. Slides themselves do NOT produce sound, although they allow preview when created/moved.

How portamento notes work

The Portamento command applies only to the transition from one note to the next. That is, causes a quick slide at the transition between notes. The effect is most audible when large tone intervals are made between the notes. The Portamento indicator should be set on the note to receive the portamento effect.

Color Groups (Slides, MIDI, Editing)

You can draw notes and slides in 16 color shades based on green, cyan, pink and yellow. To select the note/slide color, click the appropriate button on the color group selector. The color does not affect sound, it is used for independent processing of notes in the Piano roll, these include:

  • Sliding - Slides will apply only to notes of the same color as the slide note event. For example, yellow slide note will bend the pitch of yellow notes, but will ignore green notes. This way you can have up to 16 notes sliding simultaneously in different directions.

    Slide color groups are also used with the Mono mode in the polyphony settings (see Miscellaneous Channel Settings). Mono mode applies to each color group separately. So using all four colors actually can result in a polyphony of up to 4 voices at once.

  • MIDI Channels - Each color is locked to a particular MIDI channel. To see the relationships, hover the mouse over each color and look at the hint bar where the MIDI channel number is displayed. NOTE: This only applies to plugins hosted by the Wrapper, in other words, these MIDI channels will only be visible to the plugin associated with the Piano roll. To control external MIDI hardware on separate MIDI channels use the MIDI Out plugin.

  • Editing - By creating color groups you can choose to edit the properties of only notes of the selected color. This can be handy when there are overlapping notes in the same Piano roll that you wish to manipulate independently.
  • Recording notes - To record incoming MIDI Channels from a controller or MIDI sequencer to the correct MIDI note colors, Right-Click the instrument's Channel Rack button and activate the 'MIDI channel through' option.

NOTE: Some plugins use note colors for special functions. For example Harmless, Harmor and Slicex.

Note Properties Dialog

The Note Properties pop-up is an alternative way to set notes properties. It's particularly useful when you need to set different properties for notes that start simultaneously (so their properties appear as one in the integrated event editor). Double-click a note to display the properties pop-up box.

  • Levels - These controls allow changes to per note - panning (PAN), note on velocity (VEL), release velocity (REL), channel filter cutoff (MODX) and channel filter resonance (MODY). NOTE: MOD X/Y can also link to custom parameters as set in native plugins. Harmor has Mod X/Y controls that map to these parameters, for example.
  • Slide - Slide ON / Slide OFF. Determines if the note will respond to slide events. Porta - ON, inverts the portamento state for this note. If the global portamento (see Misc Channel Settings) for this channel is off, for this note it is on and vice versa.
  • Color - Click on this to select the color channel group the note is on.

    NOTE: If the note you double-click is a part of a selection, then the properties you set apply to all notes in that selection. The Time section is not available in that case, because the selected notes might have different length or start point.

  • Time - Change the Start Time (note position) in bar:step:tick. The length of a 'tick' depends on the PPQ setting. Reducing PPQ mid-song will reposition any notes not falling on an exact Bar or Step boundary.
  • Duration - Change the Note duration in bar:step:tick. The length of a 'tick' depends on the PPQ setting. Reducing PPQ mid-song will reposition any notes not falling on an exact Bar or Step boundary.
  • Reset - Resets note properties to levels they had before launching the properties box.
  • Accept - Apply your awesome changes!
