NB01 – distortion/sustainer by Noizebox – KVR Challenge 0 (0)

NB01 – distortion/sustainer is the first plugin from Noizebox Industries. Made for KVR DC21.

Inspired by a circuit from an ancient guitar pedal that was originally intended as a soft-distortion-sustainer for guitars. Giving that singing sustain without a lot of harsh distortion. This is a modern take on the same circuit, not a straight up clone, more of a work-alike inspired by the original circuit. Though a fair amount of work has gone into modelling the peculiar anomalies of an overdriven, asymmetrically clipping, amplifier circuit with a FET-based feedback loop that works like a crude compressor, prone to overcompensating.

NB01 adds control over the amount of compression applied and the response time. It its fastest setting it is not really a compressor as it starts altering the waveform of the incoming sound. It also add tone controls for more versatility in shaping the sound. The tone controls are a mix of pre and post filtering that makes them interact with the overdriven amplifier circuit in interesting ways.

The signal chain is processed with 4x times oversampling with high quality elliptical downsampling filters to limit aliasing and accurate modelling. Real time parameter smoothing for glitch-free operation. Written in native C++ for performance and small footprint. Hardware accelerated, vector based UI.

Use it as overdrive before a guitar amp plugin for a sweet, compressed and singing tone. Preferably with a bit of midrange boost to cut through. It’s is also perfect for destroying drum loops. Either by rolling off the bass and making the compressor slam the transients.

Or by cranking up the low end for really making the compressor duck like crazy on the kicks, by setting the response time to moderately fast, you can tweak the gain knob to find a sweetspot where the bass triggers the compression in just the right way.

Or try it on any other material, lofi vocals, adding grime to basslines or any other creative ways of destroying sounds.


  • Gain: Sets the gain of the circuit, higher values produce more distortion.
  • Compression amount: Sets the amount of compression applied. There’s a lot of range here. At extreme settings the compression will be negative, i.e. a 3 dB volume increase will result in more than 3 dB gain reduction. This can cause a bubbling/pumping/grinding artefacts at some combinations of high reaction speed and high compression when the circuit switches back and forth between overcompensation. This is not a bug, it’s a feature and lot’s of weird distortions can be discovered here.
  • Compression Speed: Sets the reaction time of the compressor feedback, higher values create more distortion as the compressor starts to chew on the waveform rather that the envelope of the sound.
  • Stereo: This switches between Fully independent stereo processing, stereo processing with linked compressors and mono processing.
  • Tonelomidhigh: Tone controls are fairly straight forward. All controls at 12 o clock means a reasonably flat response. Tone controls are also a combination of pre and post clipping, which creates more interesting textures.
  • Scope: Just for amusement really. but it’s fun to watch.
  • Master level: Sets the output volume for balancing the mix.

discoDSP OB-XD v2.4 x64 VST VST3 AU WiN MAC LiNUX [FREE] 0 (0)

OB-Xd is based on the Oberheim OB-X. It attempts to recreate its sound and behavior, but as the original was very limited in some important ways a number of things were added or altered to the original design. OB-Xd was designed to sound as good and as rich as the original. It implements micro random detuning which is a big part of that sound.

What’s new

• 7x faster GUI controls.
• Linux build.
• Standalone app.
• Signed and notarized installers.
• Updated JUCE framework to 5.4.7 for better stability and compatibility.
• Updated Banks with 2.0 compatibility.
• Ilkka Rosma Dark Theme.
• macOS Catalina support.
• MIDI CC Learn.
• MIDI CC support.
• Parameter refactor.
• XML based skinning.
• HiDPI (Retina) ready GUI themes.

What’s new
• Preset browser bar (switchable using MENU button).
• Added FXP preset and FXB bank files drag and drop support.
• New MIDI CC XML config menu.
• Enhanced MIDI learn. Bindings will be saved to Documents > discoDSP > OB-Xd > MIDI > Custom.xml file for all instances.
• Enhanced Standalone app.
• Fixed preset sync issue.
• Fixed LEARN button led click issue.


While not copying originals, some of the features were taken to a better point. Continuous blendable multimode filter (HP-Notch(BP)-HP in 12 dB mode and 4-1 pole in 24 dB mode). Also, like many synths of the OB-X’s generation, the OB-Xd has no internal effects so its sounds and textures can be greatly enhanced by the use of additional processing like chorus, reverb, delay, etc.

Thanks to 2Dat for the original OB-Xd and Soshi Studio for giving the rights to continue this wonderful product. Also thanks to all KVR artists for making the amazing skins!. OB-Xd Desktop has no restrictions and is free to use. Buy to support further development, thank you! Source code is available under GPL license at GitHub.




Spatial Audio SPARTA v1.5.0 VST WiN MACOS LiNUX [FREE] 0 (0)

SPARTA is a collection of flexible VST audio plug-ins for spatial audio production, reproduction and visualisation, developed primarily by members of the Acoustics Lab at Aalto University, Finland.

• Download links of current and past versions can be found here.
• The suite has been formally presented in this publication, with the source code made available here (GPLv3 license).
• The SPARTA installer also includes the COMPASS suite, the HO-DirAC suite, CroPaC Binaural Decoder, and the HO-SIRR room impulse response renderer. These plug-ins employ parametric processing and are signal-dependent, aiming to go beyond conventional linear Ambisonics by extracting meaningful parameters over time and subsequently employing them to map the input to the output in a more informed manner.
• For the curious researchers and/or spatial audio developers: note that the plugins included in the SPARTA installer are all built using the open-source Spatial_Audio_Framework (SAF).

List of plug-ins included in the SPARTA installerThe SPARTA suite:
• sparta_ambiBIN – A binaural ambisonic decoder (up to 7th order) with a built-in SOFA loader and head-tracking support via OSC messages. Includes: Least-Squares (LS), spatial re-sampling (SPR), time-alignment (TA), and magnitude least-squares (Mag-LS) decoding options.
• sparta_ambiDEC – A frequency-dependent loudspeaker ambisonic decoder (up to 7th order) with user specifiable loudspeaker directions (up to 64), which may be optionally imported via JSON configuration files. Includes: All-Round (AllRAD), Energy-Preserving (EPAD), Spatial (SAD), and Mode-Matching (MMD) ambisonic decoding options. The loudspeaker signals may also be binauralised for headphone playback.
• sparta_ambiDRC – A frequency-dependent dynamic range compressor for ambisonic signals (up to 7th order).
• sparta_ambiENC – An ambisonic encoder/panner (up to 7th order), with support for up to 64 input channels; the directions for which may also be imported via JSON configuration files.
• sparta_ambiRoomSim – A shoebox room simulator based on the image-source method, supporting multiple sources and ambisonic receivers..
• sparta_array2sh – A microphone array spatial encoder (up to 7th order), with presets for several commercially available A-format and higher-order microphone arrays. The plug-in can also present objective evaluation metrics for the currently selected configuration.
• sparta_beamformer – A spherical harmonic domain beamforming plug-in with multiple beamforming strategies (up to 64 output beams).
