Scylla

Scylla is a free software synthesizer developed by de la Mancha. Available format(s): VST for Windows.

Scylla is a VST instrument that combines sample playback with subtractive synthesis to produce a wide variety of sonic possibilities. 3 samplers and 3 different types of oscillators allow many forms of sound design, including wavetable, granular, sample looping, phase distortion, morphing and spectral synthesis. More spice is added with granulizing, ring modulation and all the (un)usual envelopes, LFOs and filter options.

Included in the package are 165 original samples, including single waveforms, tuned loops and diverse recordings. The default bank of 128 presets by brian botkiller cover leads, basses, pads and fx.

For unlimited possibilities, you can also load your own samples in Scylla and use the inbuilt custom looping, granular playback and other sampler options to make new sounds out of old ones.

Features:

Three layers of programmable audio sources.

Each layer consists of:

Sample player capable of loading full-length samples and custom waveforms.

Oscillator (Dual-OSC with cross-modulation, Morphing OSC, Spectral OSC).

Each sampler features:

Playback: Oscillate, Play-Once, Loop-Release.

Basic audio playback features (normalize, stereo to mono, zero-crossing).

Customizable Loop points.

Granular and Wavetable playback.

Loads any WAV format sample from your own library.

96MB of sample content, including waveforms, samples and loops.

128 presets by brian botkiller.

All audio sources have independent tune, volume, and pan.

Ring-Modulation per layer.

Variable stage Filter per Layer.

Adjustable Amp and Filter Envelopes per layer (Envelope contours can be changed).

Layer Assignable Granulator engine.

2 layer assignable LFO effects for modulating ring-mod, cutoff (filter), and phase of one LFO.

Adjustable Global Amp Envelope.

Mix level of each audio source can be adjusted.

Mix level of each layer can be adjusted.

Master Volume.

Each audio source, envelope, ring-mod and filter can be switched off to save CPU.

MIDI CC support.

Scandalous

Scandalous is a free software synthesizer developed by CC4. Available format(s): VST for Windows.

Scandalous is a monophonic scanning oscillator virtual studio instrument with independent speed control or pitch based speed control to scan across six oscillators with various waveshapes housed in two sections; Two envelope controls for each section; Portamento controls for each section; Reset selectors; Coarse and fine tune controls for each oscillator in Section A; LFO controls for each oscillator in Section A; and filter & reverb effect units.

Sandra

Sandra is a free software synthesizer developed by Fsynthz. Available format(s): VST for Windows.

Sandra is a hybrid AM+FM subtractive synth specially designed to produce low rezo sweeps and drones. In the mid-range it yields thick and lash polysynth chords. Leads and basses may be of consideration as well.

Features:

“boiling”, “whispering”, “icy”, “sandy” sound textures.

4 different stereo-tools (may be used simultaneously).

The special mode: “longer notes – longer release”.

Modulated with rocking frequency (with “auto” mode).

Compact GUI with tooltips on controls.

RMXL

RMXL is a free software synthesizer developed by Krakli. Available format(s): VST for Windows.

RMXL is a re-release of a plug-in previously included as a Computer Music exclusive (it is to all intents and purposes a re-clothed RichmanCM). It is the best Richman synth to date with two totally independent sound sources and a wide variety of patches from electric-himalaya.com.

RMXL uses a hybrid of Physical Modelling and FM synthesis and is designed to be an expressive plug-in. Specializing in plucked or struck tones the Richman synths can also turn their hands to a great many other types of sounds.

Like RichmanCM, RMXL has some special features including the fact that each sound generating ‘line’ is totally independent meaning that they can have their own portamento, Glide or Mono/poly settings. Some of Himalaya’s patches show the mixed Mono & poly mode off to a very good advantage. Other improvements include Envelope modulation of the pre-filters and a much wider tuning range for line two.

Ridiculously Red

Ridiculously Red is a free software synthesizer developed by CC4. Available format(s): VST for Windows.

Ridiculously Red is intended for live use due to its drone capabilities with knobs that automate knobs, but it can also be used normally to create dirty & gritty leads, thick basses, and pads with a sense of movement.

Features:

Three continuous oscillator selection banks.

One continuous noise oscillator.

Gate switches for each bank and noise oscillator.

Pulse width control for each bank.

Coarse and fine tune controls for each bank.

Gate switches and amount control for additive noise to each bank.

Three buttons for experimental semi-modular routing.

Three modifiers to control experimental semi-modular routing.

Amplitude envelope controls for each bank: Delay, Attack, Peak, Hold, Delay1, Break-Point, Delay2, Sustain, Release, and Overall level.

Three unique LFOs with oscillator bank routing destinations.

Envelope retriggering and portamento controls.

Patch independent velocity and volume controls.

Knob automation bank with on/off switches, smoothness control, knob rotation amount, & rotation speed.

63 non-automated patches, 64 knob automated patches, plus one blank patch.

Synth pixel dimensions: 843w x 436h.

Richman

Richman is a free software synthesizer developed by Krakli. Available format(s): VST for Windows.

Using a hybrid of Physical Modelling and FM synthesis, Richman2 is designed to be an expressive plug-in, which in the right hands can make real sounding and organic sounds.

Specializing in plucked or struck tones Richman2 can also turn its hand to a great many other types of sounds. It comes complete with 100 preset to demonstrate its capabilities.

PropheSea

PropheSea is a free software synthesizer developed by NOVUZEIT. Available format(s): VST for Windows.

PropheSea is a subtractive vector hybrid synth. It differs from most traditional vector synthesizers in that its waveforms are generated in real-time through subtractive synthesis, rather than being culled from pre-rendered ROM wave selection tables. The real-time waveform generators support a huge variety of internal manipulation.

PropheSea also has multiple LFOs, Additive Harmonic Feedback support, and a global FX section for mutating and sweetening the sound. PropheSea’s Dynamic Vector Control allows users to morph between the four waveform generators via their own hand, or through the use of computer automated vector sweeping.

ProjectX1

ProjectX1 is a free software synthesizer developed by JC Productionz. Available format(s): VST for Windows.

ProjectX1 is a hybrid bass synth featuring urban type bass sounds utilizing subtractive, FM and phase distortion synthesis.

ProjectX1 is essentially a monophonic synth but also has a pseudo stereo mode and features 3 oscillators, osc sync, 2 filters, LFO, 2 ADSRs, mod envelope generator, 2 waveshapers, tube amp and bit crusher effects, 2 modulation matrixes with 24 possible destinations with the option of signal inversion. The phase distortion osc has 2 wave generators each comprising of 8 waveforms, and the FM osc comes with 7 standard waveforms and also has a sync mode. There’s an add-on unison oscillator which includes 3 waveforms.

Each oscillator has fine tune and transpose functions and the synth also has a master fine tune control. There are 3 main modes of operation which are FM, phase distortion and FM+phase distortion with a mix knob to get more level from either oscillator. The first filter has Low Pass or HP operation and has an analog/digital emulator, bass boost, Q tap and clear/furry options; the 2nd filter acts more like a basic eq and is in a fixed mode of operation.

You can view your sounds/waveforms via the frequency analyser or onboard scope. In pseudo stereo mode you can control left and right levels via separate sliders in the master section in the top left of the synth; also in this section there is retrigger, velocity switch, master level and glide. The included LFO is host synced and doesn’t operate in free mode. The tube amp has adjustable clipping hardness, bias, and power supply regulation, clipping and/or crossover distortion. Most of the parameters on this synth can be automated via MIDI or your host automation.

Features:

3 oscillators.

2 ADSRs and 1 mod.

Frequency analyser & scope.

Mono/pseudo stereo mode.

Host synced LFO.

2 modulation matrixes with 24 destinations each.
