Generators:

3 Wave Oscillators with Sine, Saw, Ramp, Triangle, Square and two different widths of Pulse waves.

Audio rate is switchable between standard 16 bit/44 khz and 8 bit/22 khz LO-FI mode.

Graphic amplitude ADSRs and volume controls.

Output routing to one filter, both filters, or no filter.

Hard sync feedback loop.

Filters:

2 Parallel SV Filters with Lowpass, Highpass, Bandpass and Band Reject modes.

Graphic ADSRs routable to cutoff, resonance, or both. Knobs to control amount of envelope applied.

Pan and volume controls.

Effects section:

No frills distortion device.

Efficient reverb unit. Normal, gated and freeze modes.

Modulation devices:

2 Tempo-synced LFOs with 20 waveforms and wave modifier options.

1 Free-tempo LFO, 2 Graphic ADSRs (modulation also from velocity, aftertouch and mod wheel).

16 step tempo sync gate that mixes independently with all 3 oscillators.

6 slot modulation matrix with 8 sources and 63 targets.

More:

Phrase Arpeggiator with several modes, tempo synced.

Designed to be quick and easy to use. Large, visible, color coded interface.

Most parameters are controllable via MIDI.

black

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

Black combines a 3d oscillator form with ‘chaos’ producing filtered feedback to produce a complex textural synthesis engine with several degrees of continuous variation.

Two ‘performance modulator’ LFOs feature 60 contours including a selection of strange attractors and atypical sequencing options. The gui includes an oscilloscope display.

Black is ideal for producing sounds that will leave people wondering how they could have been made.

BillaBoop

BillaBoop is a free drum machine VST plugin developed by MTG. Compatible OS(s): Windows.

BillaBoop is a voice-driven drum synth, developed by Amaury Hazan at Music Technology Group (Pompeu Fabra University, Barcelona). It lets the user control drum synths, samplers, and effects with their voice, and focuses on percussive signals.

Segregation of the vocal stream into three drums (Bass Drum, Snare Drum and Hi Hat) is achieved using machine learning techniques, so that the user has few tweaks to do to start to control the drums. Two segregation modes are available, the first uses a beat box model made with the recordings of beat-boxers and behaves well for microphone control, while the other tries to separate the incoming sounds (more intelligent but less predictable), and is more efficient for processing complex polyphonic recordings.

The system is implemented as a VST plug-in (Signal Analysis, Onset/Offset Detection, Vocal Hits Segregation) coded in C++ with CLAM Library for Audio and Music library. It works using a frame size of 1024 samples and is fast enough for real-time performance.

NOTE: BillaBoop is currently only really suitable for use in the Plogue Bidule modular framework to control synthesizers, effects, and samplers and the download includes a Bidule layout. They plan to improve the compatibility with other plug-in hosts in the future.

Becrux

Becrux is a free software synthesizer preset pack for Tyrell N6, made by ZenSound.

TyrellN6 Becrux is a new collection for u-he TyrellN6 formed by 60 patches.

Becrux is full of distorted, grainy, unstable and detuned analog sounds — rough and experimental just like TyrellN6.

This soundset all about dark and cinematic sounds, inspired by the music of John Carpenter, Trent Reznor and S U R V I V E.

Formed by raw analog basses, dystopian pads, distorted powerful leads, going out of tune synths and keys, thrilling science fiction effects, all the sounds of this soundset are noisy and slightly erratic which makes of Becrux the perfect soundset for dark electronica and darkwave projects.

Free download, install and drop a few patches into your projects to get inspired.

Contains:

PDF with a detailed installation guide.

60 presets.

Normalized volumes.

Velocity sensitivity.

Modwheel control.

Price: 0 €.
