Update history

June 2024 update (v0.522)

  • Overall changes

    - Knobs now redrawn at a slower rate. Automation redraws even slower. Not as smooth motion but more importantly uses less CPU.
    - Other micro optimizations of FS schematic

  • GUI updates

    - VST Only: Zoom and Day/Night mode now hopefully recalled when DAW loads plugin in a project (only tested with Reaper DAW)
    - P3C knob now indicates current interval if such an Osc Module is selected
    - Frontpanel "MIDI Unison" shortcut-button changed so it no longer opens info message box. Info is still available under it's dropdown
    - Activation indicators under the About-screen now contain clickable shortcuts to the different panels/sections

  • Bug fix

    - Schematic issue caused by FS with some redrawing of LFO1 Uni/bipolar offset previews... hopefully fixed

May 2024 update #3 (v0.521)

  • Mute & Solo

    - Solo button "S" added to Aux Oscillator
    - Mute and Solo for Aux Oscillator now only affects Aux Oscillator and Osc Module. Likewise the different modulation sources Mute- and Solo-buttons does not affect the Aux Oscillator anymore.
    - As before, Mute "M" buttons are saved with preset and can be automated. But Solo "S" buttons are only temporary... and disabled when changing view/panel.

  • Other updates

    - Miniature filter curve illustration added to UI, to aid especially when using ZDF filter combos
    - Knob activation-buttons (yellow) no longer open info message boxes if they are not activated (yellow)
    - Some internal fixes/changes
    - Other minor changes and visual queues added

    - A darker theme introduced for those who can't stand the highly subtle coloring of the original UI :-)
