Note Sequencer

The Note Sequencer (N-SEQR) is a device that you can use to place notes on a grid to create a looping pattern. It is an easy way to start the device chain that results in audio.

You can specify the notes that you want to hear, or randomize the note grid before connecting this sequencer to an audio generator device and then into an output device to hear the result.

Device Options

All of the settings that can be manipulated with the Patchwork Tool can also be adjusted using the Customize panel in Create mode, or using the Details panel in UEFN.

Other Device Options

In Edit mode, walk up to the device and press E to reveal the device options. The options below can only be adjusted in the Customize panel in Creative, or the Details panel in UEFN.

Note Grid

The note grid is where you select the specific pitches you want to hear played at the end of the chain. Target and select notes to toggle them On and Off.

Note names are displayed on the left side of the grid. They will change when you change the key using the Music Manager device.

When set to On, a note plays its pitch as the playhead passes the step it’s on and lasts for the duration set by the number of cells the note is sustained over.

Point to the grid, and click the note you want to activate. It will play every time the playhead passes over it.

You can click and drag the note across two or more grid columns to achieve a Sustain effect. Drag to the onset of the next note or to the edge of the grid, if there are no other notes in that row.

Direct Event Binding

Following are the direct event binding options for this device.

Functions

A function listens for an event on a device then performs an action.

1. For any function, click the option, then Select Device to access and select from the Device dropdown menu.

2. Once you've selected a device, click Select Event to bind the device to an event that will trigger the function.

3. If more than one device or event triggers a function, click the Add button to add a line and repeat these steps.

Events

An event tells another device when to perform a function.

1. For any event, click the option, then Select Device to access and select from the Device dropdown menu.

2. Once you've selected a device, click Select Function to bind this event to a function for that device.

3. If more than one function is triggered by the event, click the Add button to add a line and repeat these steps.

Using Note Sequencer in Verse

You can use the code below to control a Note Sequencer device using Verse. This code uses all features of the Note Sequencer device API. Modify it to fit the needs of your experience.

using { /Fortnite.com/Devices }

using { /Verse.org/Simulation }

using { /UnrealEngine.com/Temporary/Diagnostics }

# A Verse-authored creative device that can be placed in a level

note_sequencer_example := class(creative_device):

    @editable

    NoteSequencer:patchwork_note_sequencer_device = patchwork_note_sequencer_device{}

    # Runs when the device is started in a running game

    OnBegin<override>()<suspends>:void=

        

        Sleep(5.0)

        NoteSequencer.Disable()

        Print("Device Disabled")

        Sleep(5.0)

        NoteSequencer.Enable()

        Print("Device Enabled")

To use this code in your UEFN experience, follow these steps:

1. Drag a Note Sequencer device onto your island.

2. Create a new Verse device named note_sequencer_example. To learn how to create a new device in Verse, see Create Your Own Device Using Verse.

3. Open Verse Explorer and double-click note_sequencer_example.verse to open the script in Visual Studio Code.

4. Paste in the code above, compile, and drag the Verse-authored device onto your island.

5. Select your Verse device in the Outliner.

6. In the device’s Details panel, assign the object reference for the NoteSequencer to the Note Sequencer device on your island. You can use the eyedropper to pick the device in the viewport, or use the dropdown and search for the device.

7. Save your project and click Launch Session.
