SHB-1
SHB-1 is a free amp simulator VST, Audio Unit plugin developed by Ignite Amps. Compatible OS(s): Windows 64b, macOS.
SHB-1 is based on the real SHB-1 “Extreme Bass Head”, built by Ignite Amps for Federico Fulceri, bass player of the Italian thrashers Subhuman, featuring 6 triode stages and a 1300W Class D power-amp.
Every single component in the signal path of the real analog circuit has been taken into account and modeled in the best possible way to match the original sound, keeping an eye on CPU performance and real-time playability at the same time.
SHB-1 is meant to be used as a bass amplifier for live playing and jamming, tracking or mixing inside hosts capable of VST or AU plug-ins support.
Main Features:
- Dynamic 12AX7 / ECC83 coupled triode stages analog modeling.
- Mono / Stereo processing support.
- Selectable oversampling rate (up to 8x).
- Global input / output level controls.
- Double precision (64-bit) floating point mathematical model.
- Fully automatable controls.

SH-009 Monosynth
SH-009 Monosynth is a free software synthesizer developed by Postdawn Nurseries. Available format(s): VST for Windows 64b.
SH-009 Monosynth is an emulated Roland SH-09 (Roland does not endorse this plug-in of course). It is pretty close in functionality and sound to the hardware version. Highlights include a LFO modulator with random / sample-and-hold step voltage that can be used to modulate the oscillator, the filter, and the pulse width. It also includes an invert switch for the envelope, which can modulate the filter and pulse width, as well as the amplifier.
Two versions are included: a VST instrument and a VST effect. The effect version can be used as an insert or in a modular host to process external audio through the filter and to control the filter envelope.

SGA1566
SGA1566 is a free overdrive and saturation VST, Audio Unit plugin developed by Shattered Glass Audio. Compatible OS(s): Windows 64b, macOS.
SGA1566 preamplifier is loosely based on a single channel all tube vintage preamplifier. To achieve the most authentic analog sound, the whole circuit is simulated in real time using the high performance circuit simulator. This level of sound fidelity comes at a price of high CPU utilization. For cases where such a CPU hit is prohibitive, we have added a model that is significantly less CPU intensive but slightly less accurate than the circuit simulation.
Use SGA1566 preamp to add warmth to a track, as a saturation compressor, or to add “dirt” with tube overdrive.
Features:
- Authentic analog sound through real-time high-performance circuit simulation.
- Preamp featuring two 12AX7 voltage amplification stages.
- CPU friendly model of the circuit.
- Two-band active Baxandall EQ that can be placed either at the beginning or at the end of the signal chain.
- Up to 4x oversampling.
- Mono or stereo processing mode.

sg-grainbot
sg-grainbot is a free software synthesizer developed by Synthgeek. Available format(s): VST for Windows 64b.
Grainbot is an experimental synth based on granular synthesis and mathematically generated noise. It’s not made for traditional bass/lead/pad type stuff (though it can do that if pressed), but it is capable of a wide range of other sounds: mechanical and engine-type sounds, rhythmic percussion sequences, random bleepery, drones, ambiences, and more. It can also process external audio.
There are two sound sources: the grain generator (which can granulate internal sound sources or an audio input), and “gen 1”, a chaotic math-based sound generator. There is also a ring modulator which uses these two generators as its inputs. You can choose between 5 different input sources for the grain generator: live audio input, a built-in analog-style oscillator, the input amplitude modulated by the oscillator, gen 1, or audio input from a file. The sound generators are processed through a filter with 5 types (lo pass, hi pass, notch, and 2 flavors of band pass) and a selectable number of stages. There is also a stereo delay effect which can sync to host tempo (or not). Various parameters (including the delay effect) can be modulated with 2 step sequencers, 3 LFOs, and a 6-stage envelope. The modulation routing is provided via matrix. Besides the modulators mentioned above, there are also matrix inputs for key tracking and velocity, and a “combiner” which uses various math formulas to combine any two mod sources in various ways.
Originally released for the 2009 KVR Developer Challenge, since updated.

sforzando
sforzando is a free sampler VST, VST3, Audio Unit, AAX plugin developed by Plogue. Compatible OS(s): Windows 64b, macOS.
sforzando is a free SFZ player. Advanced sample hobbyists now have a powerful tool to experiment and share instruments without relying on proprietary formats.
It is also possible to drop SF2, DLS and acidized WAV files directly on the interface, and they will automatically get converted to SFZ 2.0. Then, they can be edited.
Powered by the ARIA Engine
sforzando relies on the same ARIA Engine that powers the ARIA Player and other products from Garritan and obviously Plogue chipsounds.
Like the other ARIA products, this player is available as a standalone and VSTi/AU/RTAS plugin on Windows or OS X and can run in either 32-bit or 64-bit.
Dedicated To Its Community
Plogue has deployed a forum dedicated to the SFZ format to help users support each other. All technical support for this product will be community driven at ARIAEngine.com.

SevenDelay
SevenDelay is a free delay VST3 plugin developed by Uhhyou. Compatible OS(s): Windows 64b, macOS.
Note: Currently Linux build doesn’t display GUI due to some problem related to VSTGUI. For Linux, LV2 version is available at https://github.com/ryukau/LV2Plugins.
Note: I don’t have mac so macOS build is not tested. If you find bug, please report it to https://github.com/ryukau/VSTPlugins.
SevenDelay is a stereo delay using 7th order Lagurange interpolated fractional delay. Also 7 times oversampled. Suitable for making sound with actively changing delay time by hand or DAW automation:
