This time, most work has been put into the sequencer. The biggest new feature is horizontal and vertical indicator lines to help editing:



The most important bug fix is to make CTRL + S save song again (Ctrl+S was overridden by a different function). Another bug fix is making auto-crossfades work when changing interior start and stop values on audio files.

• Sequencer: Let all new audio seqtracks have the
  same initial color. This color is configurable.
• Sequencer: Fix making auto-crossfades when changing
  interior values for a seqblock.
• Audio: Fix export soundfile when jack transport is
  enabled.
• Sequencer: Tweak colors for bpms, signatures, and
  markers.
• Sequencer: Change default keybinding to split audio
  file from CTRL + S to S. S is a more common
  operation, and this also fixes keybinding clash
  with saving file (which was very unfortunate).
• Sequencer: Change default keybinding to switch Solo
  from S to Shift + S.
• Mixer: Add a default keybinding Shift + S to
  switch solo of the selected instruments.
• Sequencer: Made the seqblock boxes lighter by
  default (fade/interior/speed/stretch), and also
  made these colors configurable.
• Sequencer: Paint horizontal and vertical indicator
  lines when moving automation nodes.
• Sequencer: Paint horizontal lines across all tracks
  and lanes when mouse pointer is above a movable
  object, to better show where the objects are placed
  in time.
• Sequencer: Always paint a thin horizontal line
  under the mouse pointer to show grid and to better
  visualize where objects are placed in time.
• Sequencer: Optimize drawing cursors.
• API: getSeqAutomationColor,
  getSeqblockAutomationColor, setSeqIndicator,
  cancelSeqIndicator, seqIndicatorEnabled,
  getSeqIndicatorXPos, getSeqIndicatorY,
  getSeqIndicatorType, getSeqblockColor.
