Boomed-FM II

Boomed-FM II is a free software synthesizer developed by SpearGear. Available format(s): VST for Windows.

Boomed-Fm II is a hybrid FM/Phase Distortion synthesizer which produces clean or distorted sound from many ranges: Strings, bass, keys, leads, pads, etc.

Features:

Oscillators and envelopes: Six combined oscillators (modulators and carriers). Separately for every combined oscillator, there is a Low Pass 4-pole moog-style filter with adjustable cut frequency. Afterwards there is fine-tuning and Phase modulation adjustment for an analog sense. Mixer adjusts the level from oscillators and enables or disables output.

Master Filter: Biquad filter with enveloped frequency-CUT. There are three filter modes: Constant Skirt Gain (CSG), Constant 0db Peak Gain (COPK), and Peak. If Peak is selected, Gain/Attenuation can be adjusted from -60 to 24 db.

Delay: Delay module if selected creates stereo output. “Full In” and “Normal” delay mode. The first one is used for soft distortion and feedback modulation, while other gives delayed stereo sound with adjustable speed and timing.

Chorus: Stereo input and fat stereo output with high quality signal processing.

MIDI: MIDI section allows to choose playing Octave, select Mono mode (which enables Retrigger function), There’s also velocity level and Portamento Time adjustments.

82 presets in two SoundBanks.

Blowfly

Blowfly is a free software synthesizer developed by DocNashSynths. Available format(s): for Windows .

Blowfly generates a sound-scape by applying random motion (within user-defined parameters) to the control points of a Bezier curve that defines a single cycle of the sound. Thus, both the shape and wavelength of the curve change from one cycle to the next.

Blowfly can be considered a ‘method showcase’ product as it introduces a novel dynamic stochastic synthesis technique via a functioning product, so as to bring it to the attention of other developers who may then choose to evolve and incorporate it into their existing or future products.

Of course Blowfly is useable as-is, as a stand-alone, unrestricted synth for producing a variety of new sounds and textures, just lacking in ‘trimmings’ like the ability to save and load patches.

Blood Bucket

Blood Bucket is a free software synthesizer developed by Insert Piz Here. Available format(s): VST for Windows.

Blood Bucket is apparently a pointless experiment in synthetic stupidity. Two oscillators are combined in a variety of ways to modulate a third oscillator and presets are named after parts of the human head.
