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.

ScanSynth

ScanSynth is a free software synthesizer developed by Smart Electronix. Available format(s): VST for Windows.

by mdsp of Smart Electronix

ScanSynth is a synth based on “scanned synthesis” as described by Bill Verplank, Max Mathews and Robert Shaw in this article (20KB PDF).

“To make audible frequencies, the “shape” of the dynamic system, along a closed path, is scanned periodically. The pitch is determined by the speed of the scanning function. Pitch control is completely separate from the dynamic system control. Thus timbre and pitch are independent. This system can be looked upon as a dynamic wave table controlled by the performer.”

The dynamic-string is a mass-spring physical model which is shared by all the voices and users can directly interact with the string’s evolution on the screen. Each voice has 2 scanning-oscillators and a chaotic LFO to add drift and life to the sound.
