You can export note block data as a pattern, and import it\ninto whatever song you wish.\n* Note block songs now save song looping.\n* Added a bars/beats/sixteenths display.\n* Added lines that mark each bar in a song.\n* Added an option to choose if looping should wait for the end of the bar.\n* Added an option to show or hide layer boxes.\n* Added four edit modes, which allow you to change different properties of\nnotes (key/velocity/panning/pitch).\n* Holding Shift while scrolling over a note will change a whole octave, or\nfine-tune its velocity/panning/pitch.\n* Added Macros:\n(Accessible by right-clicking a selection, or from the new macro bar)\n   * Tremolo\n   * Stereo\n   * Arpeggio\n   * Portamento\n   * Vibrato\n   * Stagger\n   * Chorus\n   * Volume LFO\n   * Fade in\n   * Fade out\n   * Replace key\n   * Set velocity\n   * Set panning\n   * Set pitch\n* Added branch export, a new layout for exporting as schematics.\n* Added a metronome function.\n* Added layer management buttons (shift layers up and down, insert, delete).\n* Added a secret clipboard editor for power users.\n* (Slightly) Improved MIDI import, and made it support note velocity.\n* Improved data pack performance; impact on tick rate should be negligible.\n* Data packs can now export notes outside the octave range by providing\na resource pack.\n* Data packs can now be exported as ZIP.\n* Data packs now allow any tempo to be imported into Minecraft.\n* It's now possible to set a custom namespace and path for data pack functions.\n* Added six types of visualizers to data packs.\n* Double-clicking a NBS file will now open the song.\n* Added the ability to export songs in previous NBS format versions\nvia the Save Options window.\n* Note Block Studio will now refuse to load NBS versions made in the future.\n* NBS format updated to version 4.\n* Improved contrast of layer icons in dark theme.\n* Prevented dragging layer stereo from changing the song tempo.\n* Fixed 'Keys to show' resetting to 20 when enabling the piano.\n* Fixed crash in MP3 and data pack export.\n* Fixed crash on opening after updating.\n* Fixed memory leak from audio emitters piling up.\n\n"
