Usage Guide (MMW4CC)

How to use MMW4CC to make charts for Project Sekai (extended features included). Last update: September 29th, 2024

Quick Overview

This is the place where chart designers ("charters") spend most of their time working on a chart after adjusting timing settings. Notes, Hi-speed, and other aspects of Project Sekai chart design elements (with extended features...) can be inspected in this window.

MMW4CC window

The sub-window in the image above is organized for clarity. This is NOT what it will look like when opening MMW4CC for the first time.

Loading and Saving Charts

  • MMW4CC can open, edit, and save MikuMikuWorld for Chart Cyanvas Score files *.ccmmwsand Universal Sekai Chart files *.usc.

  • Load charts by selecting File > Open from the menu bar

  • Save the current chart into MMW4CC Score file by selecting File > Save

  • Export the current chart into *.usc file by selecting File > Export USC

Loading Chart Music

In the Chart Properties window under Audio, load a music file by selecting ... next to Music File or typing in the path to the file. You can also adjust the music offset. The values are in milliseconds (1/1000th of a second). A higher value will start the music later and a lower value will start it sooner. The supported formats are:

  • MPEG Audio Layer III (*.mp3)

  • Waveform Audio File (*.wav)

  • Free Lossless Audio Codec (*.flac)

  • Ogg Vorbis (*.ogg)

A waveform will be displayed when the music is loaded which can help with syncing music to the notes. Selecting View > Show Waveform will toggle the waveform's visibility.

Timeline

  • Scroll through the timeline using the mouse wheel or the scrollbar

  • Hold Shift while scrolling will change the scrolling speed. Scrolling speeds can be adjusted in Settings > Timeline

  • Hold Ctrl while scrolling: Zoom in and out.

  • During playback, the timeline scrolls to follow the scrollbar (red arrow bar). To change this behavior to scroll after the cursor has passed the screen, uncheck Cursor Auto Scroll under View in the menu bar or through Settings > Timeline

  • Hold step outlines can be turned off by unchecking View > Show Step Outlines

  • The timeline background can be turned off or changed under Settings > Timeline > Background

Placing and Modifying Notes

  • Place notes by selecting the appropriate timeline tool and left clicking on the timeline

  • Select a note and drag it to move it around

  • Select and drag either the left or right edges of the note to resize it

Timeline Menu

TImeline Menu

  • Playback buttons: Previous Measure, Stop, Play/Pause, Next Measure

    • Stop: Teleport to measure 0.

  • Divisions: Select the desired note division from the division select menu at the bottom. To use a custom division, input a number between 4 and 1920

  • Snap Mode: Changes how the notes should be 'snapped' at when moving one or multiple notes at a different specified division.

    • Relative Snap: Do not snap the notes. Move it like how it is.

    • Absolute Snap: Snap a note to a desired division. If selecting multiple notes, it will move until one of the multiple notes is snapped.

    • Individual Absolute Snap: Snap all selected notes to a desired division.

  • Go to Measure: Input a positive number to teleport to that measure in the timeline

  • Timeline Speed: Change the speed in the timeline to 25%, 50%, 75%, 100%.

  • Zoom: Change how far the note appears in the timeline. Use Ctrl+Click to edit the value.

Guide Notes

Guide Notes

Guide notes are similar to regular slides with a few differences:

  • They do not count towards combo

  • The steps always use the step type Hidden

  • They fade out as they approach the end point

(*.sus only) Place a step near the end point to control the amount of fade. The closer the step is to the end point, the less fade there will be.

Hidden Hold Point

Hidden Hold Point

The start and end points of a hold can be hidden. A hidden point does not require tapping at the start or releasing at the end. It will also not count towards combo. To create a hidden point:

  • Select the hold points to hide/unhide

  • From the context menu under Hold Type select either Normal or Hidden

Context Menu

Right-click anywhere on the timeline to open the context menu. Most of the functions are self-explanatory and can be used as keyboard shortcuts.

  • Shrink Up: Places the selected notes 1 tick apart starting from the latest note

  • Shrink Down: Places the selected notes 1 tick apart starting from the earliest note

  • Connect Holds: Merges two holds together

  • Split Hold: Split a hold note to two separate hold notes

  • Repeat Hold Mids: Insert selected Hold Mids at the next division repeatedly (you can make zigzag hold note easily with this tool)

  • Convert Hold to Traces:

    • Add Traces for Hold: Add trace notes in-between the hold points. The number of traces can be changed depending on the number of measure divisions specified.

    • Convert Hold to Traces: Turn the holds into trace notes. The number of traces can be changed depending on the number of measure divisions specified. (Note: at this time, the hold flick at the end is only converted to normal trace note.)

  • Interpolate Hi-Speeds: Insert Hi-Speeds in-between the selected Hi-Speed and changes value in a linear interpolation. The more divisions selected, the 'smoother' the speed change.

Adjusting Settings

Language

Currently, English and other 5 languages can be selected. Selecting Auto will detect the current system's language and choose the appropriate language. If the system's language is not supported by the program, it will default to English.

Auto Save

Just like the original MikuMikuWorld, MMW4CC supports auto save. It is enabled by default. The interval (in minutes) and maximum number of auto save entries can be configured. Auto saved charts are located in the auto_save folder.

Timeline Settings

  • The timeline width can be changed from the Lane Width setting under Timeline

  • A separate size for notes can be applied by unchecking Match notes size to timeline width and selecting the desired note size

  • Checking Return to last tick on Pause will return the cursor to the last selected division upon pausing

Shortcut Configuration (Key Config)

  • Several actions be assigned a keyboard shortcut

  • If multiple shortcuts are assigned to an action, the topmost one will be displayed in menus

  • Add more shortcuts if needed by selecting Add. Up to 4 shortcuts can be created per action

Lane Extension

An extended feature for Chart Cyanvas. Extended lanes enable the notes to be able to be placed outside the initial boundary of the Project Sekai playfield. It can be adjusted in the Chart Properties > Metadata section. Up to 100 extended lanes can be adjusted, though the notes can be placed infinitely further away with the use of Note Properties.

Lane Extension

Note Properties

When selecting ONLY ONE note (tap, holdStart, holdEnd, flick, etc.), the metadata or configuration information about the note is shown at the note properties sub-window. The metadata can include details such as where the note is, type of notes, lane and width, and more. Here, you can adjust the value in each metadata in a very customizable way, with an additional feature of adjustable lane/width note value in decimals (e.g. 5.50 width).

Layers

You can use layers to make notes and hi-speed in a "different playing field".
