2.10.1

[2.10.1] - 2026-05-03

FIX

• Fixed arrangement synchronization so orchestra arrangement changes now stay in sync with related UI state and mixer/channel mappings when instruments are added, removed, reordered, or replaced.

2.10.0

[2.10.0] - 2026-04-28

NEW

• Added interactive spacer panels between layer groups with add-above/add-below actions and popup options to move groups up or down.

• Added cross-group layer selection and deletion support for audio and pattern layer panels, including coordinated shift-click selection and cleanup of empty groups.

• User-Defined Opcodes and Effects now support Csound 7 modern syntax alongside classic syntax:

  • UDOs and Effects have an explicit Classic/Modern style selector
  • Modern style uses opcode name(inputArgs):outputSig declaration and function-call invocation
  • Classic style retains traditional opcode name, outTypes, inTypes declaration with xin/xout
  • Bidirectional conversion between styles preserves input argument names and type annotations
  • Parsing and CSD import handle both single-line and multi-line modern declarations
  • Newly created UDOs and Effects default to application setting default (new setting in Program Settings for "Default UDO/Effects Style"); existing projects load as classic for backward compatibility

• Orchestra: added "Replace Instrument" action to context menu

Updated

• Introduced new Time Unit system encompassing time signatures, measures, new tempo ruler, and new time units:

  • Beat Time Units: bars.beats.fraction (BBF), bars.beats.ticks (BBT), bars.beats.sixteenths.ticks (BBST), and Csound Beats
  • Clock Time Units: time, SMPTE, samples
  • Objects may have different time units for start and end times

• Updated Jython interpreter to 2.7.3

• Product Version information now includes commit hash and build date/time

FIX

• Fixed always-on instruments to play for the full global duration including mixer extra render time, preventing premature cutoff of reverb tails and other effect decay

• Redid filechooser manager to hold on to Filechoosers so that they will
  maintain last state (i.e., last file or folder selected) between uses

• JMask:

  • Maintain name of parameter when changing parameter type

  • Show parameter name in the popup for setting visibility of parameters

• BlueLive:

  • Do not generate e-statement when generating CSD for BlueLive

2.9.1

[2.9.1] - 2023-09-10

FIX

• Issues #758 - fixed issues with selection of JMask, Tracker, and other objects
  due to issue with implementing equals()

• MIDI Input Panel: Added AmpDBFS mode where amplitude is scaled to 0-1 range.

UPDATED

  toolkit.

• Redesigned SoundObjectLibrary window: supports drag and drop reorganization,
  additional popup menu options for editing and organization

• Issue #639: Added JMask to Pattern Layers

• JavaScript objects: Replaced Rhino processor with graal.js

• Issue #625: Implemented resizing multiple selected objects and undo
  functionality

• Issue #615: Implemented Looping option for AudioClips and allow resizing from

• Issue #697: Added Test Button to slide in right panel for previewing score
  generation from object.

• PatternObject:

  • now defaults to time behavior Repeat.

  • Updated UI style

  • Fixed to save pattern when modifying number of beats. (Still clears if
    number of subdivisions changes as there isn't a clear mapping.)

• Issue #703: Add ability to edit font for BSBGroup panel title label

• Issue #672: Reimplemented keyboard arrow movement of selected BSB Objects

• Issue #502: Implemented different velocities on Virtual Keyboard keys by
  hitting different parts of the key (softer towards top, louder towards bottom)

• Issue #721: Double click marker to edit marker name

2.8.1

Notes for 2.8.1 - 2020-12-29

NEW

• Added "Open Example Project" menu option to File menu to make opening the
  examples easier

• Added new Time Behavior "Repeat" implementation and renamed older algorithm as
  "Repeat (Classic)" for backwards compatibility. New implementation will repeat
  notes up to repeat point and truncate any notes that overlap boundary.

• "Media Folder" property added to Project Properties: used for certain
  operations to copy files into the media folder which should be a child of the
  project root folder (or the root if the property is left empty).

• BSB File Widget: Added "Copy to Media Folder" shortcut in popup menu that will
  copy the selected file to the media folder and update the value to use the
  version found in the media folder.

• Implemented Copy audio files to media folder on import option in Project
  Properties which will be performed when importing audio into Audio Layers
  (via drag and drop), drag and drop onto soundObject layers, or changing audio
  file in AudioFile soundObject editor

• The Blue Manual is now managed as a separate github project and published
  online at https://kunstmusik.github.io/blue-manual. Documentation help menu
  now opens the online site.

• Issue #497: Implemented comment fields for BSB widgets that appear as tooltips
  when in usage mode. Added "Show Widget Comments" menu option to View menu to
  turn on and off showing of the comments in tooltips.

• PianoRoll:

  • implemented rendering of notes in object view on timeline

  • New user-defined fields for PianoRoll and and field editor for notes; fields
    allow adding additional pfield values for notes that are graphically edited
    (similarly to how Velocity is handled in many MIDI-based DAW PianoRolls).
    User can customize how many fields and kinds of fields to use for PianoRoll.

  • Introduced dark area in background to show repeat point or scaled time area
    for notes

  • added keyboard shortcuts for undo (ctrl-z), redo (ctrl-shift-z), toggle snap
    (alt-s), and select all notes (ctrl-a)

• Issue #520: Render waveform for Frozen SoundObject freeze file

• Issue #480: Option added for Score to follow current playback time when
  rendering project

UPDATED

• Issue #396: Updated how selected score objects are rendered; rather than all
  white, now uses white border, lighter derived background colors, and shows a
  bar at top behind object label

• Issue #514: redid comments component for instrument editor and SSO to use
  Netbeans editor component to enable code repository option

• Issue #392: made copy buffer shared between all BSB interface editors

• PianoRoll: note templates for notes are now set to use the PianoRoll's note
  template by default but permit overriding on a note-by-note basis; backwards
  compatible with prior note template system but more convenient given the new
  Field system.

• Restored using Rhino JS interpreter as Nashorn was removed from Java 15

• Issue #532: Made zoom in/out buttons use a timer to repeatedly zoom when
  button is down and stop zooming when mouse is up (Score Timeline, PianoRoll)

• Issue #524: Implemented checkbox editor for NoteProcessor properties that are
  true/false

• PianoRoll and Tracker: Time Behavior set to Repeat by default

• Tracker: "Steps per beat" property added to control start/duration generation;
  useful in conjunction with repeat behavior

• Issue #539: UX improvement to select newly added instrument in Orchestra
  Manager

• Default SoundObject duration changed to 4 beats from 2

• Jython interpreter updated to 2.7.2

FIX

• BSB: PresetManager dialog had bugs when dragging and dropping nodes around

• Clojure: Dependency resolution for clojars-hosted libraries was broken due to
  using older http url; fixed by updating to https://repo.clojars.org

• Audio Layers: Audio Clips were not generating use project-relative paths when
  audio files were children of project root folder

• Issue #523: Comments tab for instruments did not scroll correctly

• Issue #527: Fixed performance issue with drawing of PianoRoll canvas on Linux
  due to GradientPaint

• Issue #545: Hide global tempo editor when editing PolyObject timeline

2.7.2

Notes for 2.7.2

[release 2017.10.16]

NEW

• Mixer: Right-clicking on subchannels to remove made easier by allowing
  clicking on labels

[release 2017.09.24]

FIX

• BlueSynthBuilder - UI Editor would hang on OSX when setting Min/Max values on
  widgets due to JavaFX/Swing UI threads interactions; replaced Swing code to
  with JFX code in affected areas
