Synth Mapping Helper

Toolbox for manipulating the JSON-Format used by Synth Riders Beatmap Editor in the clipboard.

Features

For more info on each feature, check out the wiki

• Filter by note and wall types for all operations
• Changing type of notes and walls
  • Can cycle between multiple colors to make "rainbows" or alternate between single hand specials and regular notes
• Change BPM indepenent of note timing (helpful if you have a map with different BPM sections)
• Movement in XY and Time:
  Note: All operation can be done in regards to grid center, a pivot point, or the start of rails
  • Rotate
  • Scale and mirror
  • Outset (moving outwards/away by a fixed distance)
  • Offset (Translate/Move)
  • Stacking patterns
• Pattern generation
  • Spirals/Zigzags
  • Spike/Buzz-Rails
  • Stack along rails
• Rail manipulation
  • Merging
  • Splitting
  • Interpolation
  • Convert between single notes and rails
  • Snapping single notes to rails
• Cross-Platform (Windows, Linux)
  • For Windows, supports drag and drop actions (fully usable without command prompt)
• Imports directly from clipboard, and export to it
• Uses an internal format that is easy to work with (wiki page):
  • Position in editor grid coordinates (+x=right, +y=up)
  • Time in measures (starting from start of selection)
  • Angles in degrees (positive=counterclockwise)
  • Notes/Rails seperated by color and as n x 3 numpy-arrays (x, y, time)
  • Walls as 1 x 5 numpy-arrays (x, y, time, type, rotation)
  • Walls positions are adjusted to match their rotation center
• Companion application:
  • Automatic backups while mapping
  • Plot notes to spot outliers
  • View hand velocity and acceleration to find sections to smooth out
  • Show wall density and estimatation which ones will not render on quest
  • Fix wall offset between editor and game ("Finalize")

Maybe (contributions welcome)

• GUI for common operations
• Automatic smoothing
