Changes between current nightly and 1.6.5

We are planning a 1.6.6 release in late February. The reason we are doing a release so quickly after 1.6.5 is that we made several improvements and changes, and want to take a pause on doing regular production releases while we prepare for a Surge 1.7 release which will include (among other things) a skinning engine to allow designers to adapt the UI. As such, this will be our last production release for a little while - perhaps until summer of 2020. Changes in 1.6.6 are

  • Audio and Performance Changes
    • The “Absolute” unison mode was both sample rate dependant and mis-callibrated. Correct it so that, at all sample rates, a “16hz” absolute unison is a 16hz unison spread.
    • Unison range can now be extended, giving unison spreads up to one octave (pitch) or 192Hz (absolute)
    • The Window Oscillator now supports FM, and is callibrated to use the same FM Depth as FM2/3/Sin oscillators.
    • We initialize modulators before the initial voice start, setting the first modulator value at voice initiaion corectly and avoiding a 32-sample “sweep” across a modulator value at voice onset.
    • Fix two bugs with the sustain pedal; first sustain on channels 3 and 4 didn’t work, and second pressing a key multiple times while sustain was held would lead to an incorrect state.
  • Smaller Changes
    • The VST3/Windows plugin properly formats the automation display of the CC parameters
    • The FX slots and automation parameters are named more consistently, as are several menus and labels
    • The value popup window popsup on mouse-down not mouse-move on a slider
    • The patch and wavetable menus have refresh options on the popup menu, not just in menu/data and patches
    • Slider mouse behavior in medium and slow works more like classic when over-dragging
    • Added an init patch which assigns a distinct modulator envelope to each OSC
    • Add a regtest that parameter IDs are stable across versions
    • Improve LV2 parameter management
    • Modify the build pipeline so the linux .deb file has correct ownership on shared assets

Changes in Version 1.6.5

  • New Features for Playing Surge
    • Added a “Channel Split” mode to split by midi channel across scenes, just like the KeySplit mode does with key
    • Several changes to the alternate tuning implementation
      • We have full support for scala KBM files, including full keyboard remapping, scale 0, and frequency 0 selection.
      • The default tuning constant key is Midi note 60 / 261.63 hz
      • The scale viewer shows frequencies per key
      • Correct an error where tuning could interfere with filter cutoffs and delay timings, especially with long scales
  • Changes to the Modulation Section
    • When any control is TempoSynced, show a beats- display as well as a time-display on the LFO grid (not available on Linux)
    • Temposync all controls for an LFO modulator with a single RMB gesture on any control.
    • Add LFO Envelope “Lanes” in the LFO-1 retrigger section. Use shift- or right-click on the retrigger section to trigger both the Amp and Filter envelope or just one or the other.
    • Make envelope retrigger work properly for Analog mode envelopes.
    • Choose a more on-theme blue for the step sequencer section, rather than that wierd green.
    • A “Green Line” shows how far you have modulated when you modulate a slider. Try it!
  • Changes related to MPE
    • The global pitch bend (ch0 pitch wheel) no longer double-bends in MPE mode
    • MPE pitch bend state is per instance and saved in the DAW state, so you can use two surges with mpe bend of 24 and 48 in a single project, if you happen to have both a Seaboard and a Linnstrument. Say.
  • Changes to the VST3
    • SideChain support is properly supported with a kAux channel, meaning SideChain works in Cubase Pro. Additionally, in Reaper versions > 6.02 the VST3 will properly configure routing for sidechaining when dragged into a track. (For earlier versions see here.)
    • Support VST3 context menus. Right mouse on a param in the VST3 in a modern DAW and check it out!
    • VST3 Automation for the special “CC” controls works.
    • LFO freerun works if transport is not running.
  • Change the Windows Installation Locations
    • Windows now reads shared content from %PROGRAMDATA% (c:\ProgramData\Surge) and then if missing from %LOCALAPPDATA%
    • The Windows Installer installes common assets in %PROGRAMDATA%
    • To allow debugging, the About screen on all platforms shows the data paths.
  • A new collection of third party presets from Dan Mauer.

  • Other Workflow and Engine Improvements
    • You can export a wavetable from a patch to a standalone wavetable using the export menu item in the oscillator wavetable selector
    • The Envelopes in analog mode corrected decay behavior and support sustain swells
    • The Digital envelopes in quadritic decay mode work with sustain 0
    • LFO phase is properly modulatable (modulated phase is snapped when an LFO starts and is not modulatable once going)
    • TempoSync was not correctly unstreamed on the Delay effect.
    • TempoSync in Delay is correctly initialized when first played in a new DAW instance.
    • The AU unstreams zoom properly in Logic Pro
    • The AU allows automation of the “CC” and “Master” parameters properly
  • Other UI Improvements
    • Windows Touch devices now work with the Surge UI
    • Fix a problem with a ‘spiky’ draw of the Square Wave on Windows
    • Several UI elements are higher contrast, several text displays are more consistently formatted
    • Frequency sliders (like Cutoff frequency) show a midi name as well as a frequency in their popups and string displays
    • TempoSync sliders show their status with a little “TS” on the handle.
    • FrameClose in the VST2 called at the appropriate time.
    • VST Names for FX Params are distinct per param
  • Code Changes
    • Add and activate many unit tests spanning tuning, modulation, and much more
    • Add support for builds with Visual Studio 2019

Version 1.6.3 to 1.6.4.1

Versions 1.6.4 and 1.6.4.1 were released late November 2019, with several MPE and effect changes, new content, and some small cleanups

  • Synth Sound and Behavior
    • Release velocity is now an available modulation source. See more details here
    • Sustain Pedal in MPE mode was mis-mapped to the wrong channel, leading to it not working in MPE note-per-channel configurations
    • The ‘Drive’ feature in the distortion effect is extendible
  • New Content
  • Other smaller changes
    • Mouse button shows value of integer and boolean sliders
    • Fix a small repaint bug in the LFO display
    • Handle cases where user folders don’t exist
    • Make LFO modulation button state always consistent
    • Better abbreviated names of modulation sources, with consistent case and spelling
    • Failed wav file loads include the name of the file which failed
    • Developer documentation cleanup and unit tests
  • 1.6.4.1 was a minor release that corrected the installer on macOS Catalina, renamed and completed a couple of the new content packs and fixed two small graphics assets.

Version 1.6.2.1 to 1.6.3

1.6.3 fixes a collection of problems with the VST3 plugin. We are particularly grateful to the team at Steinberg for providing us a complementary copy of the Cubase DAWs which best exhibited the VST3 bugs Surge had, and allowed us to resolve the problems.

  • VST3 Fixes galore
    • Pitchwheel and Modwheel work VST3/Cubase
    • Resolved bugs in midi mapping, midi learn, and other controller flows
    • Resolve VST3 automation inconsistently updating the Surge UI
    • Support drag-to-zoom in VST3 in hosts which support it (tested in Reaper, FL, Bitwig and Cubase)
  • Upgraded the distortion effect
    • Users can select the waveshaper for the drive stage from the set of surge waveshapers
    • The pre- and post- gain can be extended to allow outsized boosts and subsequent extreme distortions
    • Note that some settings of the distortion effect in extended mode can drive Surge well into digital clipping. Be careful!
  • New patches from Inigo Kennedy
  • Several LV2 and Linux changes, including the ability to build a 32 bit linux configuration.
  • Deal with some small bugs with wave ordering, invalid waves, menu arrow keys on Linux, and error handling when Surge is mis-installed

Version 1.6.2 to 1.6.2.1

1.6.2.1 is a point release fixing a few regressions in 1.6.2 and a few crashes our users noticed when more people downloaded the synth

  • Fix a long-standing MPE error where channel aftertouch was mis-routed
  • Restore the “extended” menu on Oscillator pitch; apply a few other cosmetic menu changes
  • Build patch menu correctly when user directory names exactly match factory directory names
  • On Linux systems without zenity installed, fail gracefully instead of SEGV
  • Apply naming consisntency to wavetables as well as patches

Version 1.6.1.1 to 1.6.2

  • Substantial New Features
    • Alternate Tunings
      • Surge supports re-tuning the synthesizer using .scl files
      • .scl files are stored in the DAW state and optionally stored in a patch
      • UI elements to see if tuning is active, to see current tuning, and to reset tuning in place
    • Greatly expanded .wav file support and WaveTable Oscillator improvmenets
      • Surge can read .wav files on all platforms (linux, mac, and windows) now
      • Surge will recognize .wav files which contain a clm block to indicate loop size (as used by Serum), a cue block (as used by various products, including Native Instruments) and a smpl block. This means that all Serum compatible wavetables we have tried now load in surge
      • Add a srge chunk type which allows wav files to advertise surge table sizes other than 2048, and a python script to add those chunks to wav files.
      • .wav files without loop information are loaded as one-shots
      • Increased the maximum table size to 4096 samples.
      • Drag and drop of .wav files, direct open with the file chooser, and scanning of .wav files in ~/Documents/Surge are available
      • The WaveTable and Window Oscillator Morph control shows the table and allow you to snap exactly to a table
    • Important Linux Changes
      • A Linux 64 bit LV2 is now available
      • A Llinux 64 bit VST3 is now available, although VST3 support in Linux is sporadic, and it only fully works in Reaper
      • Resolve problems with mis-animated, crashing, or ghosting menus in the Linux UI; and mis-aligned text fields in Reaper
    • Audio and Patch Creation Changes
      • Oscillator pitch can be set to “Absolute” using the right mouse, making the pitch shift in absolute frequency as opposed to relative note space.
      • Temposync Display values use musical values (“1/4 triplet” rather than “2.667 1/16”)
      • The SIN oscillator implements FM feedback; and corrects some errors in the FM implementation making it respond line an unmodulated FM2 when no feedback or waveshape is applied.
      • The Surge Vocoder adds tunable bands, adjustable band count, and a different set of bands for modulator than carrier.
      • It is possible to copy and paste FX between slots in the FX router
      • For some lower resolution generated wavetables, add side-by-side high resolution ones
    • Oscillator and LFO Displays
      • The Oscillator display and LFO display are both vectorized, eliminating the high-zoom pixelation of prior versions.
      • The LFO display automatically zooms to show the entire envelope; and releases the sampled LFO to show the release stage.
      • Due to a technical limitation in Linux VSTGUI that we are still debugging, these features are only available in the Windows and Macintosh build today. Also on some older machines this feature will auto-deactivate if it is too slow; and can be forcibly deactivated with a switch in the menu.
    • The SurgeEffectsBank plugin.
      • We have wrapped the FX stage of surge as a separate JUCE plugin and generated a VST3
      • This plugin is included in the mac and windows installer.

      • EMU digital and sampled wavetables added in third party wavetables
      • EMU patches added to third party patches
      • Added a few presets by Claes which we found outside the factory distribution
      • Generally reorganized the presets to have more consistent case, name, and folder sturcture.
      • Place content too large for the core distribution on a wiki site and link it through menus in the main menu, patch menu, and wavetable menu.
  • Bug Fixes, Host and DAW changes
    • Parameter automation in the Audio Unit corrected, allowing touch automation of parameters in LogicProX
    • Zoom issues resolved in renoise windows with renoise 3.2 upgrade
    • Zoom issues resolved in reaper linux by using the Linux VST3 rather than VST2
    • Oscillator copy and paste mis-copied dynamic wavetables; fixed
    • Oscillator copy and paste always copied oscillator 1; fixed
    • Automating OSCTYPE as a DAW parameter gives the correct behavior in the UI and the audio engine
    • Automating ENVTYPE as a DAW parameter updates the UI properly
    • Fix VST2 overflow which was stopping plugin from working in QTractor
    • VST3 UI responds properly to automation
    • VST3 shows parameter value strings correctly mac and linux

    • Increased contrast and correctly anti-aliased labels in several parts of the skin
    • VST3 remembers its zoom setting inside a session
    • Linux hosts with zenity installed will see error prompts, rename prompts, and other UI elements available on Mac and Windows
    • Windows mice with 5 buttons can use buttons 4 and 5 (the side buttons) to toggle modulation when over a slider or modulation source
    • The Solo UI accurately renders the state of the mixer, showing the single-solo bus.
    • Fixed a bug where modulation sliders could reset to max when dragged far below min
    • “Chan. AT” renamed “Channel AT”
    • Menu includes feedback and the surge website
    • Double clicking on a metacontrol value resets it to the 0 point
    • Fix a problem with non-integral boxes clipping UI element borders on windows at some zooms
    • The control modulation elements respond more consistently to mouse gestures changing values
    • The zoom menu can directly set a default zoom to any value
    • Saving a project in the DAW remembers the zoom state and MPE state across sessions.
    • Added a status area for MPE and Tuning status display and menus
    • Properly respond to OK/Cancel in the file dialogs in several places
    • A menu links to our additional content page.
  • Other behavior changes
    • Linux users who create a ~/.Surge directory will use that instead of ~/Documents/Surge; and if no directory is present, Surge will create ~/Documents/Surge only if ~/Documents exists.
    • Users can select their own directory for patch and wavetable storage instead of ~/Documents/Surge (although user defaults remain in ~/Documents/Surge)
    • Presets with stored values of metacontrols will load those values rather than resetting to zero.
  • Code Cleanup
    • A variety of changes to allow the factoring for VCV Rack to continue
