Changes in Surge XT 1.1

We plan to release Surge XT 1.1 sometime in Spring 2022, however no date has been decided quite yet. Here's what's done so far in the nightly, as of Jul 25th and commit 01efe591dd4de45edb2020a1f685349823c5b1b8, since XT 1.0.1 release.

  • Action History

    • Surge XT now supports undo and redo for all actions (even loading patches!) - use either the common Ctrl+Z/Y keyboard shortcuts, or buttons on the GUI
    • If a patch has been modified, it will be marked as dirty and an asterisk will be appended to the patch name
      • By default, attempting to load a different patch will prompt the user to confirm the loading action in order not to lose your patch modifications
      • This can be disabled in Menu > Workflow

  • CLAP Support

    • CLAP is a new standard for host-plugin interoperability developed by a group of open source and commercial developers. Surge XT is an early adopter and a test case for CLAP. You can read more about CLAP at https://cleveraudio.org/
    • Surge XT implements - exclusively in the CLAP version - the non-destructive modulation (both monophonic and polyphonic!) and note expressions!

  • Patch Navigation

    • Patches without categories are displayed in their own category in the Patch Browser
    • Favorites are now also displayed in the Patch Browser, in User Patches section
    • Much improved Find Patch feature!
      • Search results will now stay open by default after loading a patch, so you can quickly navigate through this list
      • Ctrl+click or Ctrl+Enter will load the patch and close the search results
      • There is now an option in Menu > Workflow to bring back the old Surge XT 1.0 behavior, if you so wish
      • Magnifier button now acts properly as an on/off toggle button
      • Your last search term is remembered after leaving the Find Patch mode
      • Search results will now open immediately when entering the Find Patch mode, instead of only when you start typing

  • Accessibility

    • Our screen reader community gave us amazing feedback on Surge XT 1.0.1, leading to several changes, improvements and bugfixes
    • Using the announcement API, we read several actions, including patch and favorites changes
    • Fixed several components (oscillator copy/paste, scene copy/paste) which used mouse position improperly to find the source and target
    • Overlay buttons (Tuning, Mod List, MSEG Editor, Formula Editor, etc.) respond properly to Enter, Shift+F10, and so on
    • Step sequencer rotate buttons are now exposed, and order of step and trigger parameters improved
    • Mod List parameter names and accesibility works well
    • Discrete parameters represented as menu buttons in the UI are now using the combo box element instead of a slider in screen readers
    • Effect tab order is now in display order, not internal storage order
    • Every text entry field has a correct focus-restoration target when dismissed
    • The patch search typeahead supports accesible navigation (fully on macOS and with narration workaround on Windows)
    • New Workflow menu options allow you to expand modulation menus to have specific edit/clear/mute submenus, rather than compound multi-click menus
    • Introduced a mode where accesible key presses follow the mouse focus, rather than keyboard focus
    • Many other small changes and fixes

  • New Overlays

    • Keyboard shortcut editor:
      • Allows freely changing or disabling any of the available keyboard shortcut actions offered by Surge XT, in case there is a clash with keyboard shortcuts reserved by your DAW
    • Filter Analysis:
      • This new overlay will show frequency response curves for Filter 1 and Filter 2, in realtime as you change filter cutoff, resonance and mixer pre-filter gain parameters

  • DSP Changes

    • String oscillator improvements:
      • Various Stiffness filter models which provide better tuning at high stiffness values. "Keytracked and pitch compensated" model is the new default
      • 2x oversampling option, which improves timbral quality for high pitched notes
      • Choose between three interpolation modes, which can limit energy loss in exchange for accuracy at high frequencies
      • Remember, right-click everything in Surge! These options are in context menus of Exciter Level and Stiffness parameters
    • Fixed an issue with Twist oscillator's LPG onset, creating occasional glitches in certain oscillator modes
    • Initial audio buffer is no longer filled with denormal noise - instead we rely on flush-to-zero (FTZ) flag in our processors
    • Sample rate is now a property of individual Surge XT instances, rather than global for all Surge XT instances - allows correct behavior when only certain instances are oversampled in hosts that provide this facility (for example, Reaper)
    • Fixed a crash when Reverb 2 was used at a very high sample rate
    • Implemented a small fade out when executing All-Sounds-Off
    • Reset filters on scene release and All-Sounds-Off - by doing so, we have removed a click on transport start in Logic Pro
    • Absolute unison mode now works for Alias and Modern oscillators
    • Scene highpass filter now has slopes up to 48 dB/oct (right-click option)
    • Output meter falloff is now sample rate independent (previously the meter would have a faster falloff on higher sample rates)
    • Fixed a bug where simultaneous chords played on the exact same tick created voices well over the polyphony limit

  • Play Mode Updates

    • Both Poly and Mono modes get expanded envelope and voice triggering modes, accesed from the right mouse click context menu on the Play Mode parameter
    • In Poly mode you can choose whether repeated strikes of the same key create a new voice or retrigger the currently playing voice (if there is one)
    • In Mono modes, you can select whether the envelopes (AEG and FEG) retrigger from zero, or from their current level if a voice is playing

  • Effects

    • Added multiple clipping options for the feedback path in the Delay effect (right-click the Feedback parameter)
    • Added option to extend the Delay Feedback parameter range, allowing negative feedback
    • Implemented the Tone filter to the Phaser effect (same as the one from Combulator)
    • Added new AirWindows effects: Cabs, Chrome Oxide, Dub Sub, Dub Center, Fire Amp, Glitch Shifter, Nonlinear Space, Pafnuty, Power Sag, Tape Dust, To Vinyl
    • Fixed a bug which could make Nimbus occasionally distort, especially in Looped Delay mode (applies to the Surge XT Effects plugin as well)
    • Spring Reverb's Decay parameter and Flanger's Count parameter now have a more accurate display and value typein behavior
    • Dragging an Airwindows effect around the FX routing grid no longer resets its parameters
    • Delay's Feedback parameter can now be extended, allowing negative feedback

  • Modulation

    • All LFOs now have 3 outputs: the signal multiplied by the LFO EG, the raw LFO signal alone, and the LFO EG alone
    • LFO attack will now start after setting up voice level modulators - this enables modulating voice LFO amplitude with velocity, which didn't work before
    • The range of the fractional part of the LFO phase is supposed to be strictly [0, 1), excluding the maximum, whereas before it could hit exactly 1, which is not supposed to happen
    • Fixed S&H and Noise LFO types not properly freerunning for Scene LFOs
    • Removed a check which improperly changed song position with DAW looping enabled and transport not running, making LFO freerun mode not working properly in some cases
    • Fixed cases where deleting nodes in MSEG LFO mode could lead to a broken envelope
    • Modulation List can now launch a value edit typein with the pencil icon
    • Step Sequencer's Deform slider now has deform types, which brings Shortcircuit's LFO Smooth method to Surge
    • Adjusted the S&H modulator so that the initial state is random, leading to less uniformity in the first few phases
    • Changed the order of voice initiation and LFO EG Attack in Latch mode so a latch more accurately represents the voice

  • Microtuning

    • Tuning Editor now contains the ability to create even division scales and three-note specified KBM files directly
    • Fixed a problem where MPE pitch bend in MPE mode with MTS enabled was using the wrong tuning system
    • "Use MIDI Channel for Octave Shift" tuning mode no longer conflicts with MPE mode
    • The Interval Between Notes display now makes it easier to see which interval you are playing

  • Larger Bugfixes

    • We initialized the audio processing state too early, which in some cases could result in the patch resetting when loading the plugin in Logic Pro
    • We incorrectly handled patch loading in the startup path of Reaper, meaning loading a Reaper session with disabled Surge track(s) would never load the state correctly, and subsequently resaving without activating the track would save the incorrectly initialized state

  • Surge XT Effects Plugin

    • Complete accessibility review
    • Implemented UI resizability through corner drag, menu and keyboard shortcuts
    • We now correctly report parameter names to host for the VST3 plugin
    • Double-clicking a parameter will now reset it to the default value
    • Added an option to run the plugin in zero latency mode - useful if your DAW can guarantee sending fixed block sizes to the plugin
    • Fixed Effect type menu not repainting during host automation
    • Airwindows Type parameter is now streamed and unstreamed properly, so that projects don't break if we add new Airwindows effects
    • Fixed a problem with integer streaming, which means that, going forward, changes in integer param ranges in Surge will not break Surge XT Effects sessions

  • UI, UX and Skin Engine Changes

    • Touchscreen mode improvements, which includes automatically using the Exact mouse sensitivity mode and long press support
    • Typein for FM3 oscillator's Ratio parameter is correctly read when typing in a modulation amount
    • Typing an out of range value for a parameter or modulation amount typein will now report the appropriate minimum or maximum value
    • Audio In sliders that are unused will now appear deactivated (semi-transparent)
    • Ctrl+click on a currently unselected LFO modbutton will bring that modulator to focus in the lower area (same as clicking the orange arrow, but now you have a larger hitzone to do it)
    • More consistent FX slot mouse gestures:
      • Double-click on FX slots will now bypass them (previously this was on right-click)
      • Right-click now pops up the more usefulFX presets menu
      • Single click works as it always did
    • The state of "Store Tuning in Patch" checkbox in the Save Patch dialog is now remembered after cancelling the dialog
    • 3D waveform display for Wavetable and Window oscillators - toggled by clicking the oscillator display (or via right-click context menu)
    • Context menus will now scale properly on Windows HiDPI displays
    • Add contextual help links in severeal places which were missing it
    • Context menu colors can now be set in skins
    • Added option to use OS dark mode setting for context menu colors, which overrides skin-defined colors
    • Skin engine can now override the global font used by Surge XT
    • Added skin connectors for placing the new overlay windows (filter and waveshaper analysis)
    • The entire Classic skin (including hovers and tempo sync assets) is now contained inside the binary
    • Added pitch bend and modulation wheel widgets to the virtual keyboard
    • Correctly constrain plugin window drag-to-resize events
    • Waveshaper Analysis overlay now uses the actual Drive parameter for a realtime overview
    • The Modulation List now has new filtering options - by scene and by target parameter's control group
    • Most tearout windows can now be freely resized
      • Double-click on torn out window's title bar reverts to the default size
    • Improve error message to be clearer in the (very rare) situations where the patch database is locked by two Surge XT instances
    • The About-screen-as-skin-layout-grid feature is back! We completely forgot to port it over from Surge 1.9!
    • Fixed a bug where the Zoom menu wouldn't allow setting default zoom level, if default zoom level wasn't at all defined
    • Wavetable oscillator's Morph parameter displayed wrong units in continuous and discrete modes
    • Mute and Solo buttons no longer overlap, which created uncertainty in which parameter actually gets clicked
    • Pressing the F1 key will now open the relevant part of the manual for currently focused (or hovered) parameter
    • Added Sustain button to the virtual keyboard
    • Make PNG loading lazy, which resolved sporadic crashes with skins that use PNGs, like Royal Surge
    • Improve Alias Harmonics editor mouse handling when mouse cursor is out of editor's bounds
    • Imporved tearout behaviour, adding an Always On Top pin button in the title bar
    • Patch comment popup width will dynamically adjust its width to fit longer comments now
    • Mousewheel in FX and Oscillator menus properly advances through submenus

  • Other Changes and Various Fixes

    • Polyphonic aftertouch is now properly processed per MIDI channel
    • Removed the Activate Scene Outputs option, which is not needed anymore due to JUCE's plugin wrapper handling
    • Favorites can now be exported and imported via .surgefav files (in essence these are CSV files with a new extension)
    • Correctly report VST3 bypass parameter and implement it in our JUCE processor
      • This should allow FL Studio's Randomize feature to stop disabling audio, and allow other VST3 hosts to bypass Surge XT as expected
    • Modbutton orange arrow state was incorrect on selection (but correct on drag gestures)
    • Fixed a bug when dragging FX slots with modulation assigned
    • Dropping a modulator on an overlay would modulate the slider underneath the overlay
    • Fixed a case where copying a modulation could duplicate a modulation routing
    • With the move to VST3 plugin bundle file format, Windows portable installs broke, so now they work again!
    • Drag and drop in the presence of overlays could corrupt Z-order of things
    • "Download Additional Content" link in the main menu didn't work, so now it works again!
    • "Absolute" option was not preserved when copying oscillators, scenes, etc.
    • We're now sending automation events from several widgets which didn't do that, leading to inconsistent automation in Cubase
    • Special characters like ' no longer break the SQLite search. No little Bobby Tables here!
    • WAV chunks must have an even number of bytes, so we've fixed our WAV parser for the case when the size is odd, preventing incorrectly reading the file - which could happen with certain metadata chunks
    • Upgraded MTS-ESP library, which allows MTS-ESP to work on Linux
    • Tuning Library can now deal with fractions up to 2^64 for numerator and denominator in SCL/KBM files

  • Infrastructure and Code Changes

    • We're making a substantial effort to move critical parts of Surge XT into libraries that other projects can use
      • sst-plugininfra provides XML, filesystem, user preferences and keyboard shortcut management, CPU information and more
      • sst-cpputils provides a collection of C++17 extensions we use a lot
      • sst-filters provides all Surge XT filters in a header-only set of templates - used as a submodule now
      • sst-waveshapers provides all Surge XT waveshapers in a header-only set of templates - used as a submodule now
    • Test case runtime substantially improved
    • Use std::thread everywhere for threading
    • Lots of improvements for the Windows installer
    • Reinstated Windows portable mode by checking recursively for SurgeUserData etc. folders
    • Use 7Zip for packing Windows ZIP files in the pipeline
    • Linux 'plugins only' archive is now a .tar.gz
    • The .deb file now contains icons and an application startup for Linux
    • Added CMake options to skip ALSA and/or VST3 builds
    • Various changes to support JUCE 7 builds (although our production build is still using 6.1.6 until further notice)
    • Fixed comments and documentation typos across the codebase
    • We now provide a cleaner compile-time error if building on a system other than x86 or ARM
    • Added ability to build a slightly reduced surge-common without JUCE or Lua (for the upcoming Surge Rack XT project)
    • Renamed the surge-py target to surgepy to avoid a -, which causes load time problems in Python
    • Made sure to cleanly join the background patch loading thread on exit if it is still running or if another patch load begins
