Radium 6.5.72 is released. This is a big release with many bug fixes, some new features, and many minor improvements.

Most work this time has been used improving A/B settings in the mixer. Transitioning from one setting to another is smoother, and some bugs have been fixed. General CPU usage for audio should be lower as well in some situations because of this work.

In addition, it's also possible to select which A/B settings you want to apply:

For windows users, this release contains two significant improvements:
1. Fix that it was impossible to move the mixer window when running in it's own window. This bug was introduced in 6.4.76.
2. Prevent virus killers from scanning Ladspa plugins during program startup. Sometimes this could delay program startup time by many minutes. Startup time has been reduced significantly on Linux (and probably macOS) as well.

Some other notable features are: working modulator connections in .mrec files, mute/bypass/solo works for event connections as well as for audio connections, options to load prev/next vst program, options to load prev/next preset file, popup-menu for mixer connections, and various improvements to latency handling.

Note: Due to partial lockdown, I have not tested the macOS release this time. Please report immediately if it doesn't work.

Changes 6.4.77 -> 6.5.72:
* Windows: Fix borderless mixer window. Bug
  introduced in 6.4.76.
* Mixer: Fix remembering window position.
* Sampler instrument: Add entries to edit keybindings
  to the popup menu of the "R" button.
* Audio: Add entries to the instrument effect popup
  menu for adding keybinding to change effect
* GUI: Increase performance a little bit for effect
  sliders and other things.
* Instrument widget: Fix immediately updating graphics
  of solo and mute buttons when changing solo.
* Mixer: Add "Insert plugin" and "Connetion enabled"
  entries to the connection popup menu.
* Instruments: Remove the "T" (through) button for
  MIDI instruments (served no purpose).
* Audio: Cache ladspa plugin info so that they don't
  have to be loaded during program startup. Only
  info for included ladspa plugins are cached for
  now. This fixes very long startup time on windows
  when realtime virus scanning is enabled, but even
  startup times on Linux (and probably MacOS) is
  notably shorter.
* Audio: Generally improve CPU usage by being more
  aggresive about not mixing audio when the output
  of a sound object is silent.
* Audio: Increase audio level allowed to autosuspend
  a sound object. May lower CPU usage in some
* Windows: Remove some unnecessary info from
  crashreporter message.
* Audio: Increase number of frames to fade out/in
  from 1024 to 2048 when changing mute on/off and
  various other things.
* Audio: Don't recalculate latencies on the fly when
  a sound object is muted, auto-suspended, volume set
  to 0, and possibly other situations. Although
  constantly running mimumum latencies uses less
  CPU, doing this can also cause audible artifacts.
  E.g. if a plugin reports a latency of 2048 frames,
  we always compensate for a latency of 2048 frames
  in parallel running sound objects in the audio
  graph, even when the plugin makes no sound.
* Modulators/preset: Fix modulator connections when
  loading .mrec files.
* Mixer: Fix undo when creating new sound object
  from preset file by using keybinding.
* Mixer: Fix assertion window popping up when
  creating new sound object from preset file by
  using keybinding.
* Mixer: Make it configurable which A/B settings to
  apply. Click the button with a settings icon to
  configure. The options are:
  * audio connections
  * event connections
  * volume
  * panning
  * mute/solo/bypass
  * system effects
  * instrument effects
  * instrument states
  * mixer strips configuration
  * remember current instrument
  * modulator connections.
  * system volume
  Only audio connections, event connections, volume,
  panning, "mute solo bypass", and "remember current
  instrument" are enabled by default in new songs.
* Sequencer: Fix wrong editor seqblock positions
  after undoing changing block tempos.
* Mixer: Update connection line gfx immediately
  after changing solo for an instrument.
* GUI: Fix Return and Enter keys working in tables.
  Bug introduced in last release .
* Plugins: When loading song, don't try to set
  illegal program number if program number on disk
  is a negative number or higher than the number of
  programs provded the plugin. Fixes crash in at
  least one AU plugin.
* Audio: Don't send events though (i.e. when "T" is
  enabled), when an instrument is implicitly muted
  and "Implicitly mute MIDI the same way as audio"
  is enabled.
* Audio: Fix updating implicit mute/solo when
  removing a connection.
* MIDI: Add the option "Implicitly mute MIDI the
  same way as audio" to song properties. I.e. when
  soloing, we also mute MIDI in implicitly muted
  instruments. This option is enabled by default for
  new songs, and disabled by default for old songs
  (to make sure they continue to sound the same).
* Audio: Make transition from one A/B setting to
  another much smoother. Now solo, connections, and
  instrument effects are all changed at the same
* Audio: Fix latency compensation being wrong in
  some (very) rare cases when recording from system
  input. Happened sometimes when there were event
  connections in the audio graph.
* Preferences: Make it clearer what latencies are
  used in the "Latency compensation when recording
  from system input" option.
* MIDI: Compensate for latency when playing notes.
  By default it only compensates for "System out"
* Preferences: Changed tab order a little bit.
* Preferences: Moved various things from the "Audio"
  tab to the "Instruments" tab.
* Instrument widget: Support right-clicking the
  A/B-buttons and the GUI button.
* Sequencer: Less experimental default granulation
* Mixer: Remember current instrument in a/b.
* Instrument widget: Support right-clicking the
  "Replace" and "Load" buttons to configure
* FaustDev: Fix missing info from the info window.
* Instrument widgets: Don't display multi-presets
  when asked to load/replace preset.
* Disk: Don't put program into an endless message
  loop when loading an erroneous .rad/.rec/etc.
* Instrument widget: Add "prev preset" and
  "next preset" buttons to quickly switch to
  previous or next preset in the directory where the
  instrument was loaded from (if loaded from preset
  file). If instrument was not loaded from a preset
  file, select prev/next preset from default or last
  used directory instead.
* Instruments: Save preset filename to disk if
  instrument was loaded from a preset file.
* Audio: Name VST/AU programs and not presets.
  "Program" is the common name, plus that "preset"
  can be confused with radium presets.
* Instruments widget: Remove the program number-
  widget. Incorporate the number into the program
  name-button instead.
* Instruments widget: Add "prev program" and "next
  program" buttons. Assign keybindings by
  right-clicking the buttons.
* Instruments widget: Immediately update autosuspend
  button graphics when changing autosuspending type.
* Audio: Change instruments to not send out events
  (i.e notes, MIDI messages, etc.) when they are
  muted. Same with bypass. Old songs behave as
  before, but this can be changed in the Song
* GUI: Draw an SVG image for the various "reset ab"-
  buttons. Before this, a question mark was drawn
  instead of the curly arrow utf-8 character when
  running on windows.
* Editor: Add option to select current block in the
  popup menu for the padlock-checkbox in the lower
  left corner.
* Sequencer: Remove graphical garbage from the row
  of pixels placed between the seqtrack headers and
  the area to the right of the headers.
* Editor: Fix various error messages popping up when
  switching current block while moving a pianonote.
* API:
 * New: getNumInstrumentPrograms,
   getInstrumentProgramName, getDirPath,
   getPathWithoutDir, getInstrumentPresetPath,
   getInstrumentPreset, selectInstrumentConfigNum,
   instrumentEffectExists, getInstrumentEffectType.
 * Deleted: setInstrumentIsImplicitlyMuted, setInstrumentIsImplicitlySoloed

Radium 6.5.73 released. Emergency release to fix crash if changing A/B in the mixer while creating a connection. Probably an old bug, so it probably doesn't happen very often, but it's still a crash bug.

Changes 6.4.72 -> 6.5.73:
* Mixer: Don't crash if changing A/B while creating
  a connection.
* API:
  * Fix documentation for getInstrumentEffect and
  * New: getStoredNativeInstrumentEffect.

Heads up: Several Ladspa plugins outputs audio only in the first
channel in Radium 6.5.72 and 6.5.73. A new version should come up
later today, but until then you can fix this manually by deleting all
".cached_type_info" and ".cached_library_info" files under

Radium 6.5.74 released. Emergency release to fix broken mono ladspa plugins.

Changes 6.5.73 -> 6.5.74:
* Audio: Remove some unnecessary audio buffers that
were used when processing Ladspa plugins. Might
decrease CPU usage by using less CPU cache for
audio data. (Note that badly written Ladspa
plugins could misbehave after this change.)
* Audio: Fix audio only in left channel for mono
Ladspa plugins where plugin info was cached to
avoid having to open the plugin during program
startup. Bug introduced in 6.5.72
