Xfer Records - Serum - Changelog / Release Notes

Note: This was originally extracted from the HTML returned from the https://xferrecords.com/api/update_check/serum API, converted to markdown, and then the formatted manually cleaned up a bit further. It probably won't be kept strictly up to date, but it should at least serve as a useful historical record.

Note: For releases that I had access to the *.exe/*.dmg files for, I have also included the SHA256 hashes of the official downloads; so that they can be used to verify the authenticity of any versions that you might come across. At time of writing, the first version below that includes the hashes is 1.36b8 (October 11 2023)

Prior Art:

Table of Contents:

1.36b8 (October 11 2023)

  • add: Rescan Folders on Disk now rescans WT Editor formulas
  • add: incoming MPE Pitch Bend now also routes to the "MPE X" mod source. This can be disabled in SerumPrefs.json if (un)desired.
  • add: MPE Enabled state, and the Locks for tuning and oversample (Global page): these will now save/load as part of your default preset (/User/Default.fxp).
  • add: preference in SerumPrefs.json to "MPE Y acts BiDirectional", for MIDI controllers which offer/expect a bi-directional movement for the Y axis.
  • add: preset saving improved to no longer trigger a rescan of the preset database.
  • fix: MIDI Program Changes pointing to no file in ProgramChanges.txt will no longer produce "file too small" messages when the target filename is blank
  • fix: potential first-run crash when updating Serum directly from a very old version.
  • fix: (SerumFX) Note Latch button was not visually updating after loading presets in to SerumFX.

  • Fix: Alt key was not reacting on AAX Windows
  • Fix: In 1.29b9, graph curve handles were not drawing on X-Shaper / Remap graphs
  • Fix: Adjusting LFO 5-8 rate with notes playing was not reacting until new note
  • Fix: Updated Mix/Level image artwork

1.29b9 (May 23 2020)

  • Fix: Typing entry values for the new FX level knobs (click the mix knob label to access) was responding in percentages instead of the dB range
  • Fix: Drag modulators to LFO graph was flickering in some OS/DAW combinations
  • Fix: Drag modulators to exactly LFO point (instead of X Y) was assigning (to another point) when it should do nothing
  • Fix: typing negative values setting LFO rate in Hz mode would get accepted in some situations
  • Fix: changing the preset browser filters/search could leave the previous row location in the list selected.
  • Fix: modulated icon on numeric controls not drawing the indicator greyed when the mod source was unfocused
  • Add: Improvements to LFO drag to point handling + cosmetics
  • Add: Remove LFO modulation points checks if the bus is no longer used by points, and if so, removes the bus mod matrix entries

  • Fix: Preset browser was appearing blank in some situations
  • Fix: alt-drag LFO to wavetable improved

1.29b7 (May 18 2020)

  • New: LFO Point modulation

Right-click (ctrl-click MacOS) on a point in the LFO Graph, you will see “Modulate X” and Modulate Y” options on the pop-up menu.

You will then see a list of (in use) LFO Busses plus one empty one (e.g. you only see "LFO Bus 1" only when starting a new preset) followed by a list of Mod Sources.

By selecting a mod source, you are Creating a Matrix assignment (Selected Mod Source -> LFO Bus) and also the point association (e.g. point X axis->LFO Bus).

The busses allow for multiple points to be controlled by a single Matrix assignment/depth.

You can e.g. drag-select multiple points and assign them to the same bus.

  • New: drag-export last played note as wav file.

You should see a waveform icon appear when mousing over the very top-left of Serum's window (top-left corner of SERUM logo).

Drag this to the DAW, it records the last played note+velo+duration to a file (Serum Presets/Renders/).

This is a replaying of the note, so the result is like playing the note again (e.g. will not be literally identical in sound if random or BPM-sync features are enabled).

Please note: you are creating audio files on your hard disk by using this feature (they don’t ‘magically’ get created in the DAW project, that would be nice if it were technically possible), so management of these files is up to you. Serum does not use them directly itself, but if you drag it to your DAW, your DAW may now be referencing this file. If you drag a lot you will end up with a lot of audio files in the Renders folder, so you may want to consider file management techniques (e.g. relocate or consolidate if using in a project) ahead of time. You can alt-click the drag export button to open the Renders folder in the OS.

  • New: Hi resolution resampling of Serum's skin bitmaps on Windows (gets macOS resampling quality).

Since this is heavy computation (slow), to speed up opening Serum, the resized images get cached (`%APPDATA%\Xfer\Serum) of the last set skin+zoom size. So Serum will resize slower when setting the zoom to a new setting, or selecting a new skin, but if you save the size and/or skin as the default(s) in the SERUM logo menu, then opening should be faster than ever on subsequent openings of the window.

  • New: automation parameters for the 8 LFO Rise, LFO Delay controls - these controls were not automatable in the DAW previously.
  • New: Level Trim controls for the effect modules

Clicking on the MIX switch on any effect mix knob will expose a modulatable level parameter, to attenuate or boost the output from any effect. This can be useful for attenuating the effect chain level to e.g. match Direct Out oscillators, or gating/muting sound as well as boosting (e.g. in front of distortion for more drive).

  • New: velocity (click Y location) to clicking the onscreen piano keyboard
  • New: “init all LFOs” to main menu
  • Fix: when at 110% zoom, tooltip numbers were drawing overlapped on adjusting AHDSR controls modulation depth popup value (note: it is likely there are similar value-display issues to locate and fix)
  • Fix: manual value entry on distortion Q below 0.1 would crash
  • Fix: better browser support for nested folders, truncated text in the preset filters when using Sort by Location
  • Fix: polyphony limit handling / released notes were getting priority over held notes in some situations.

1.28b6 (Jan 22 2020)

  • fix: (AAX) Serum was not restoring all settings on a deactivated track/instance.
  • fix: Shift-click + dragging on the leftmost segment of the LFO display would add a stream of extra LFO points.
  • fix: Alt-drag to LFO to wavetable
  • fix: drawing in WT Editor would not update the wavetable in some situations

1.28b5 (Jan 17 2020)

  • fix: In 1.28b4, if piano keys were not showing on window open, clicking the preset menu and preset advance arrows unresponsive.
  • fix: (SerumFX) in some situations, using "Audio In" feature on noise oscillator was displaying erroneous errors and/or not passing audio on MIDI notes.

1.28b4 (Jan 9 2020)

  • fix: Copy Osc feature now preserves interpolated tables in the WT (it was rendering them out previously).
  • fix: (Windows) fixed a versioning issue causing 1.282 to display an earlier version number on the file properties.
  • fix: (Windows) allows automatic authorization for secondary user accounts for academic/shared workstations (MacOS version already allowed this).

1.28b2 (Dec 26 2019)

  • fix: resizing the UI with playback active could crash in some situations

1.28b1 (Dec 24 2019)

  • fix: since 1.27b7, using FFT editing or WT-to-FFT button in WT Editor could halt audio playback.

1.27b9 (Dec 23 2019)

  • fix: since 1.27b7, wave drawing in the WT Editor was not processing in some situations

1.27b8 (Dec 21 2019)

  • fix: under Windows OS in 1.27b7, using drag to resize could lead to a crash

1.27b7 (Dec 20 2019)

  • add: 2 new distortion types (Stomp Box, Tape Sat)
  • fix: very short noise samples (<100 ms) could create a memory issue on patch/song reload.
  • fix: resizing the window could lead to a crash on macOS

  • fix: mono legato with FM depth was causing clicks on new notes in some situations
  • fix: improved preset changing

1.27b6 (Dec 14 2019)

  • add: preliminary spectrum view - click on filter
  • add: Check for updates to Menu, pings Server to compare local version to the one available for download.
  • add: embedded tuning files that contained no name no longer display as (none) but not will display (special).

This most often stems from a rogue tuning file (often if not always a 432 Hz file).

If you have a preset that is out of tune and displays (special), you can command-click (ctrl-click Win) on the (special) and it will clear the tuning file.

Once cleared, Alt-click on the disk save button at the very top is a quick way to overwrite the preset, if desired.

  • fix: DSP issue with noise osc and high pitches that could lead to problems
  • fix: DSP issue with chaos oscs potentially producing invalid output
  • fix: minor cosmetic issues with parameter display on lower knobs.

  • Fix: compressor not catching first peak on very first playback on an instance
  • Fix: MPE MIDI Channel 16 was not reacting to expression

1.24b2 (March 21 2019)

  • fix: sending MIDI Program Changes could potentially trigger multiple times, leading to a ‘preset missing’ message or possibly a crash.
  • fix: In 1.24b1 Windows, if Serum Presets folder was missing, user was not prompted to choose the new folder location.
  • fix: using MPE->Macros features would provide incorrect depth for the MPE to some destinations (if the associated macro had multiple destinations).
  • fix: Text files accompanying wavetables set to interpolation on wouldn’t register as interpolated

1.24b1 (March 18 2019)

  • fix: value tips were not drawing properly for Matrix curves

1.23b2 changes (Mar 6 2019):

  • add: default oversampling level now (optionally) can be set in Serum.cfg fle (otherwise 2x as usual)
  • add: WT Editor->Add/Remove menu->Reduce submenu: thins the number of frames, in order to easily keep only every Nth frame.
  • add: ability to get a separate vertical grid size for the LFO with text entry: double-click on grid size (assuming pref enabled) and type e.g. 8,12 for 8 horizontal and 12 vertical grid lines.
  • add: secondary sort method for preset browser, Serum will remember the previous column you clicked for ordering and use that as a secondary ordering:

e.g. click Location column, presets are sorted by location.

Then click Rating column and the presets will be sorted by Rating, but the sorting within a given rating will be ordered by Location.

  • add: alt-drag LFO tile to WT now an offcial feature / works on Windows too
  • add: preset name is now rescanned on Serum instances re-opening (for checkmark / menu advancing)
  • add: resizable interface (lower-right corner), zoom menu in top-left (Serum logo) and preference/setting in Zoom Menu for default window size.
  • add: if oversampling is set in confg to non-2x the oversampling lock will also enable.
  • add: “Export All as Single-Cycle Waves” to the export menu in WT editor: exports WT as a set of individual single-cycle wave fles.
  • add: skin support. zoom menu (Serum logo in top-left) will select skin. A few points about skins:
  • add: custom .ttf font support for skins - see colormap thread here in Serum user forum for example (in download) You can e.g. copy the folder "Default" in Skins subfolder, and make changes to any images. there is no need to include images that you do not alter - Serum will look to Default skin folder as a fallback.
  • new Scream Filter, Dist.Comb 1 and 2 flter types
  • Ringmod flter needs less “warm up time” to respond to audio signal.
  • Ringmod and S H flters custom flter display instead of frequency response plot (which was of little value for these flter types).
  • Preliminary MPE support. You will see the MPE settings in the main menu, and can be enabled/disabled by default in the preferences.
  • Preset Hybridize: takes visible presets in browser (e.g. flter to a type) and randomly combines part of seeral presets.
  • Promethium Skin by Lance Thackeray as a second factory skin
  • Preference to the confg fle for scaling the automation smoothing rate. This will affect onscreen controls, MIDI CC’s, and song/host project automation.

It is not advised to change this parameter (as existing project automation might sound different), it’s a tweak offered for “power users” or fringe situations where less automation smoothing is desired (e.g. for rapid response over automation parameters). you can scale it (e.g. [50] would be 50% smoothing, or twice as fast. Accepted values are 1 to 800 (0 = default which is 100%). Rename or delete your confg fle to have this entry created in the confg fle.

  • add: signifcant CPU reduction when modulating WT Pos.
  • new: Custom (user text entry) category in browser
  • WT Editor FFT bins right-click additional feature: “Snap vertical draw to quarters” quantizes FFT Bin mouseclicks to 0, 25, 50, 75, 100%
  • WT Editor FFT bins right-click additional feature: “Scale Freq Values by Bin Index”. This makes higher bins scale relative to their bin location, for example normally a saw wave would show the bins scaling lower as you go to higher bins (which is the true amplitude values needed for a saw). When this feature is enabled, drawing a fat line across the FFT Bins at 50% will produce a saw.
  • unison phase memory trigger (MemTrig): Triggers the unison voices with the same relative phases each note on. This makes an effect similar to a sample, where the unison will start identical each new note (without the “laser zap” effect of having all phases simply zeroed). To activate, turn RA D and PHASE knobs to 100% on an oscillator to enable MemTrig. Lower the Rand knob temporarily (while playing a note or notes) to get a new randomized set of phases. These phases will save in the preset/song.
  • WT Editor -> Process Menu -> Set Spectra same for all Frames (from current): applies FFT bins (spectrum) from current frame to all frames. This feature may not be terribly useful beyond education, it was mostly added because it is an easy permutation of the next one:
  • WT Editor -> Process Menu -> Set Phases same for all Frames (from current): applies the FFT phase information from current frame to all frames. This is useful to make all tables match in phases beyond just the fundamentals for e.g. solid/consistent sound during morphing.
  • WT Editor -> Process -> "Subtract Spectra from other Osc": Removes the (relative amount) of harmonic content contained in the corresponding other oscillator. This applies to all frames (as the process menu always does).
  • add: Retina/HiDPI support. (Skins note: 1x folder images are now only used for non-retina displays and when Serum is 100% size or smaller)
  • add: noise osc direct out switch
  • default preset: if you save a preset as default.fxp (or Default.fxp) located in /User subfolder of /Presets, Serum will load this preset on new instantiations of Serum.
  • Fast matrix assignment for vibrato in Matrix drop-down menu (next unused LFO to Global tuning)

1.11b3 changes (Aug 10 2016)

  • fix: issue for Splice lease users
  • fix: issue with noise oscillator in loop mode clicking at loopback in some situations

1.11b2 (Aug 8 2016)

  • fix: arrow keys on preset browser window were no longer working

  • fix: in 1.10b8, parameter labels on Reverb were not displaying

1.10b8 (July 30 2016)

  • fix: presets > 4 MB of size would not load (presets couldn’t be this large prior, but was made possible due to noise embedding)
  • fix: Env3 AHDSR params did appear as assigned modulators on mod source drag-tile tooltips
  • fix: using MIDI program changes with GUI closed would stop working after a program change, and require preset browser rescan
  • add: individual band threshold control (0-200 percent) for the Multiband compressor (and as mod destinations)
  • add: mix control for the compressor
  • add: “pan” (cutoff offset) knob for the FX Filter (same function as the main voice filter’s pan knob)
  • add WT import of stereo file to OSC B will import right channel of WAV file (for “pseudo stereo” abilities using both oscillators)
  • add: Resample to A+B (Stereo) option in main menu, left output resamples to Osc A, right output resamples to Osc B

1.10b7 (Jun 30 2016)

  • add: option to lock polyphony count (right-click the POLY number box in lower-right) to have the polyphony persist preset loading
  • fix: oversampling lock, while working in DSP, but wasn’t preventing the visual update of oversampling switch when presets were loaded.
  • fix: using a noise sample containing loop points was getting mangled when toggling one-shot/loop mode on the noise osc.
  • fix: AAX fix for ProTools 12 first run
  • fix: potential crash in 1.10b6 in some hosts when closing a project containing Serum

1.10b6 (Jun 19 2016)

  • fix: byte alignment incompatibility issue in 1.10b5 presets when sharing between 32- and 64-bit versions of Serum. 1.10b6 should correctly load all presets / projects.
  • alt-drag to copy between LFOs was not working on LFO 5-8
  • LFO 5-8 were not displaying free rate times in Hz

1.10b5f (Jun 17 2016)

  • fix: issues for ProTools AAX (Plugin not appearing, bypass engaging on preset change)
  • fix: issue in 1.10b5 with Noise arrow button < > navigation on the internal noise folders not functioning
  • fix some issues with modulator tile drawing

1.10b5 (Jun 16 2016)

  • add: 8 LFOs: hidden by default, until LFO4 is used, then you will see LFO5 appear, etc.
  • add: drag and drop support for Noise Oscillator: the noise file will embed in the preset/song in these situations.

.. You will notice the background get a blue tint, this is to indicate the noise file is embedded in the preset/song.

.. You can advance < > noises in the respective folder once a first sound is dragged in.

  • add: noise files when load without fine tune when pitch track is enabled (sample rate is recognized / thus no pitch offset)

.. so the Noise fine tune shouldn’t be needed if your source sample is in tune.

  • add: Alt-click on “MOD” column entires in the Matrix to toggle between (normal / active modulation) and Bypassed

..(saves a menu selection to audition bypasses)

  • improved: Noise Fine control modulation depth ‘arc’ more accessible (was overlapping with the control’s up/down arrows)
  • improved: typeable values for noise osc in key track mode follow display
  • add: Option (preference) for Noises to be embedded in presets. This isn’t recommend to enable, as you’ll be bloating your project files:

..It’s the 13th brackets entry in the Serum.cfg file. If you delete the Serum.cfg file it will list it as such “Embed non-factory noises inside presets (warning: larger presets / songs!)” this is intended currently for soundware developers and isn’t recommend to enable for local use (you’ll end up with larger songs and presets when using custom noises).

  • add: Serum Preset Browser now has additional 4th column choice: “Comment”, for personal comments in browser.
  • add: Serum Preset Browser now saves the last selected 4th column choice / opening new instances will default to this column choice.

OS X: Serial number no longer prompted when keeping Serum Presets on an external HD and sharing between machines.

  • fix: for Velocity or Note graph controlling Noise Phase (noise sample start)

1.10b3

  • “render OSC Warp” could lead to crash in some situations - loading old presets/projects wouldn’t open in some situations in 1.10b2 - preference for make double-click to reset controls instead of ctrl-click/cmd

1.10b2

  • fix: on Windows, dragging Note or Velo modulator across the LFO or Velo/note graphs could lead to a crash in some situations. - fix: PNG to WT import was offset by 1 pixel (empty row at bottom of image, missing top row of image). - fix: compressor knobs (when set to Limiter) latency reporting was causing glitching issue in Cubase as latency updated repeatedly (please note, compressor attack time will still do this, as attack time alters the needed lookahead for the limiter, thus the latency needs to adjust). Automation parameters are no longer sent on preset change, this greatly accelerates preset load times in some hosts (e.g. FL Studio)

1.10b1

  • add: PNG (image) to WT import -> drag PNG to WT, it load PNG, stretches to internal 2048x256 size, maps luminance to WT amplitudes.
  • add: preference for preventing MouseWheel to change controls (knobs/number boxes/switches/etc).
  • add: alt-click on Matrix mod source (and Aux source) menus: batch re-assign all entries w/ same source to the new selection.
  • fix: ModWheel->WT pos preference was not saving
  • fix: clearing note / velo graph (using context menu) wasn’t visually updating immediately
  • fix: selecting FX rack presets for Filter were not updating the Filter type label immediately
  • fix: delay FX module would on occasion create audio clicks (when setting/modulating delay time)..
  • fix: Remove DC Offset in WT Editor wasn’t functioning correct (only partial DC elimination + potential clipping).
  • fix: right-click to reset an env curve wasn’t working correctly (it visually would update, but it wasn’t updating in DSP)
  • fix: mod source menus had checkmark set wrong in some cases
  • fix: adjusting polyphony limit while a new note is triggered could lead to a crash
  • fix: presets which were not accessible due to permissions could cause a crash on database scan

1.09b9

  • reduced memory footprint by ~60 megabytes per instance fix: “Silence effect tails when host transport stops” preference now functions on Hall reverb mode fix: mouseover tooltip names now display correctly on hall reverb size/spin/spin depth

1.09b8 (Windows Only)

1.09b7

Unison phase memory (setting phase knob to 100%) no longer drifts on successive notes/ this phase-lock saves in preset/song.

E.g. Enable unison, turn unison detune to 0, successive notes will sound different due to rand knob.

When you hear one you like, move phase knob at 100%, now the oscillator phases (resulting tone) will be locked consistent.

  • fix: improved voice stealing / no more “rude” polyphony clicks are gone when voice cap is hit
  • fix: [Reaper 32-bit] situation where operating the UI could cause playing notes to stop reacting to automation.
  • fix: (OS X) on some systems, the installer would not complete in 1.09x
  • fix: (Windows 7) potential fix for drag-and-drop macros on causing crashes in 1.09b5/b6

1.09b6

  • fix: saving a remap/waveshape shape file was leading to a crash new defaults for the reverb FX (hall settings).

1.09b5

  • add: Second reverb algorithm: Hall Module Locking (Osc A, B, Noise, Sub, Filter module, right-click on the name/power button to see menu item), locks the controls/tables so you can change presets and keep the old settings presets for individual effect modules.
  • add:clicking an FX tile on left side of FX page will scroll the FX rack to reveal that FX module (assuming the FX is enabled)
  • add: MIDI CC / Learn support for OSC A, B, Noise, Sub, Filter module power buttons
  • add: some Preset and project loading time improvements
  • fix: typeable values on filter cutoff (Hz) was applying the wrong amount slightly.
  • fix: chaos modulators would stop functioning if S&H was disengaged with an active note
  • fix: (non S&H chaos modulators) were not functioning correctly in polyphonic situations fix: (SerumFX) re-opening projects causing an instant crash in some hosts (if LFO + Note Latch were assigned)

1.09b4

  • updated installer for OS X (script to force-remove older versions)

1.09b3

  • using older compiler revision due to issue on older MacOS machines running 64-bit

1.09b2

  • code merge/update to match SerumFX

1.08b6

  • fix: modulating pitch (or mono mode) on a tiny noise sample (< 1k) set to one-shot mode could lead to a crash
  • new: Lock FX Rack - when enabled, the current FX chain/settings will not change when you load new presets.

This option can be found in the main menu (“Menu”) as well as if you right-click on the FX Enable tiles on the left side of the FX panel.

  • new: Load/Save Effect Chains. Allows you to load/save the current effect rack. Accessible in the same as above locations.

Although the location of these files does not matter, a folder named “Effect Chains” should get created in the Serum Presets folder and be the default directory for the load/save dialogs. If it does not get created, you can create it yourself (without quotes).

1.08b5

  • fix: closing the plugin window with both the FX tab selected and preset browser showing could lead to a crash.
  • fix: all notes are shut off when adjusting polyphony now to prevent possibility of a crash.
  • fix: potential fix for Master Tuning host automation parameter not functioning in some situations
  • fix: Poly Legato fix/reworking to handle simultaneous note on messages

1.08b2

  • fix: in v1.081 some params such as unison detune range were not getting default values set on INIT preset which could lead to improper sound or a crash in some situations.
  • fix: Poly legato mode (legato on, poly off) was not sounding legato in some situations (most recent note stopping before new note).
  • fix: Velo/Note graph legato mode option (ctrl-clicking on their mod sources when assigned for the option) was not sounding in some voice stealing situations.

1.08b1

  • preliminary parameter locking feature, right-click menu option on controls to “lock them” (to prevent change on preset load). underlying changes for SerumFX version (ready soon, no ETA date). some OS X fixes (crash protection)

1.07b9a

  • fixes voice stealing where new notes weren't getting created at all when polyphony was exceeding maximum voices set in POLY.

1.07b8

  • fixed a potential crash, caused by new notes getting triggered during processing (e.g. Wavetable or preset load).

1.07b7

  • (OSX) updated compiler to more recent SDK (compatibility with older OS versions is NOT tested at the moment, 1.07b3 is uploaded as a secondary option, but feedback to me is greatly appreciated (even if things seem OK) via contact formå.

1.07b6

  • (OSX) attempts to fix an issue in 64-bit hosts (namespace collision?)

1.07b5

  • is 1.07b4 but version # updated to avoid confusion with short-lived 1.07b4.

1.07b4 (November 2015)

  • fix: for selecting “init preset” while notes are playing
  • fix: for chaos oscillators resetting the chaos algorithm when no notes were playing
  • fix: for using variables q and z together in a formula in the WT editor could lead to NaN output.
  • fix: dragging NOTE and VELO mod-source tiles on Windows could lead to a crash
  • fix: Filter cutoff Hz (numeric value display) was incorrect in some situations.
  • fix: Drag and Drop import in Ableton Live OS X 64-bit could appear “stuck” or crash
  • fix: WT Editor, it was possible to draw on a different table than visually selected
  • fix: extremely large sample sizes in WT formula editor were displaying improper text for note name.
  • add: support for drag-and-drop to wavetable (import for audio files) from Cubase Media Bay
