New version 1.3.1
Old version 1.3
Release Notes v1.3.1 - A new "Hold" mode for the Arpeggiator, the old hold mode is now called "Latch". As long as at least one note is held down on the keyboard or via MIDI any other notes played will be added to the held chord. When all notes are released the chord continues to play until another chord or note is played. This makes it possible to play a chord on the keyboard and then change the key or sequence by playing another chord. All existing presets will load and play as before in Latch mode. - Added a new parameter editing panel in the editor: The "Dial Strip", see Link & Assign section in manual. Dial Strip pops up a line of dials, one for the same parameter in every layer. Use the strip to edit parameters in other layers and set links between parameters. - Added view insets for devices without home buttons. - Added an “Invert” button for Unipolar FM in the oscillator. This inverts the polarity of unipolar modulation. - Added a button to the Editor menu bar to choose between Link Assign/Dial Strip or none. - Fixed audio unit crash when host requests large buffer sizes. - Fixed: Fixed character filtering that replaces some unusable characters from preset names before saving. - Fixed: Voices with long attacks and long releases are no longer (incorrectly) restarted from the wrong level. - Settings View: Performance MIDI channel selector is now greyed out if option is disabled. - Some minor DSP engine optimisations. - Updated Manual with new features in v1.3.1
