Update History

Version 1.3.8
(Build 40)
June 26, 2019


Bugs Fixed

  • Fixed an issue where the top of some scores might get cut off in the transformation editor’s preview area.

  • Fixed an issue where short left to right strokes failed to recognize.

  • Fixed an issue where grace notes following a 16th note or quicker were not behaving properly.

  • Fixed an issue where you couldn’t change an interior note in a tuplet to a grace note.

  • Fixed an issue where rests in a beam group were sometimes drawing with a half beam. This issue was inadvertently introduced in v1.3.7.

  • Improved spacing of dotted notes.

  • Whole measure rests are now centered in the measure.

  • Certain expressions such as dynamics and tremolos can now only appear on a note once. Adding a different different dynamic (for example) simply changes the existing one.

  • Improved vertical centering of grace notes on line or space. 

Features Added

  • Dragging on a bar line in the measure number bar will expand that measure stack by adding space in between every note. This is very useful when trying to insert new notes in between notes that are very close together.

  • Now restoring last zoom and staff positions when opening saved documents.

  • Transposing notes from the Action menu now also transposes chord symbols and fretboards.

  • New “Live Change” button in Static Palette allows direct duration change of tapped note(s) to current palette duration and note/rest.

  • Added a user option to designate an Auto Save interval.

  • Added tremolos (in expressions) with playback.

  • Revamped the expressions/dynamics/shapes palette into a single palette. Now always in “Live Mode” so palette can stay open while inserting new expressions.

  • Added ability to place a tuplet number without a bracket beam side (in addition to number + bracket note side). Added context sensitive “Flip Tuplet” toggle.

  • Tuplet panel now defaults to most common triplet based on selected note’s duration.

Known Issues

  • Undo after a multi-staff copy/paste is still problematic. Best is to save your score before attempting any large undos. 

  • Collisions between voices may occur and will be addressed in the next release.

Version 1.3.7
(Build 38)
April 30, 2019

Bugs Fixed

  • Fixed an issue where the float rest user preference was stepping by half spaces even though it was labeled whole spaces. The problem is that half and whole rests could sit both on and hang off of lines when in the presence of another voice which was wrong.

  • Chord symbols and/or fretboards now sound even if present on tied-to notes.

  • Fixed an issue when trying to insert a note, sometimes was hitting a ‘dead’ spot where the insertion wasn’t working.

  • Fixed an issue where it was possible to insert a new note in between two tied notes and the tie would remain.

  • Added a user context sensitive menu option to re-beam whole measure(s) to default beaming.

  • Added a user sub-division field in the meters panel along with a reset to default, allowing custom beaming groups.

  • Added global reset all subdivisions to action menu.

  • Added global reset all break/join beaming to action menu.

  • Can now include rests in beams via user option to break/join beam.

  • Added a new pitch dragging mode: “Direction” which moves chromatically up by sharps and down by flats.

  • Added various alerts to actions (from the Action menu) that perform global functions, providing an opportunity to cancel.

  • In addition to the default “Cycling” notes/rests/tools palette (with only one of the three visible at a time), a “Static” palette has been added (Options: “Notes/Rests Palette”) which shows all notes, rests, and tools at the same time.

  • Added a fretboard baseline offset preference in Advanced Settings.

  • Added a chord count to information statistics.

Known Issues

  • Undo after a multi-staff copy/paste is still problematic. Best is to save your score before attempting any large undos. 

  • Collisions between voices may occur and will be addressed in the next release.

Version 1.3.6
(Build 37)
March 18, 2019

Bugs Fixed

  • Fixed an issue in copy/paste that resulted in missing ties, slurs and other shapes. This happened when trying to paste from two or more staffs.
