MIDI Instruments: Not into audio processing? That’s Ok, Cabbage lets you easily build MIDI only instruments.

Signal Gen: Users have up to 1300 different signal generators/modifiers available.

Control Widgets: Csound can be used to control the state and behavior of any widget. This means widgets can be programmed to move around the screen, change colour or size, morph or fade into other controls, as well as lots of other funky operations.

GUI Controls: GUI controls, include sliders/knobs/buttons, xy-pads and waveform/envelope editors, checkboxes, text editors, file browsers, etc. GUIs can be implemented directly in simple mark-up language, or via drag and drop once in Edit mode.

Theme with SVG: Customise your Widgets with Scalable Vector Graphics (.svg’s).

bx_solo

bx_solo is a free stereo imaging VST, VST3, Audio Unit, RTAS plugin developed by Brainworx. Compatible OS(s): Windows 64b, macOS.

bx_solo is a tool that Brainworx designed to get you started with, and used to, the way they approach the M/S technique – be it for recording-, mixing- or mastering purposes. The “heart” of their M/S tools are the Solo Buttons that allow you to actually listen to all components of a stereo mix / stereo signal individually:

L(left channel), R(ight channel), M(ono sum) & S(tereo difference signal) – all phase corrected (when needed) and mono-ed out on both speakers of your system. This is helpful when working in M/S modes and to check your signals / mixes for errors, noises, clicks, whatever…

bx_solo also contains a stepped M/S stereo width control, so you can get an impression about what you can actually do with it.

Buzz Cut

Buzz Cut is a free limiter and clipper VST, Audio Unit plugin developed by GMH Audio. Compatible OS(s): Windows 64b, macOS.

Buzz Cut is an audio clipping plugin designed for ease of use and great sound. The intuitive scrolling waveform display gives a clear visual depiction of the processing and makes the settings easy to dial in. The “HQ” mode offers a cleaner sound for when hard, digital clipping produces too many artifacts. While mixing, Buzz Cut works great for leveling off drums and percussion while retaining the impact of the transients. In a mastering context, clipping with Buzz Cut can allow the perceived volume of the audio to be increased without raising the peak levels.

.

This plugin is available for PC as a 64-bit VST and Mac as 64-bit VST and AU formats. Download includes instruction manual.

Buffer Synth Alpha

Buffer Synth Alpha is a free buffer synth VST plugin developed by ndc Plugs. Compatible OS(s): Windows 64b, macOS.

Buffer Synth Alpha is a lo-fi performance effect. It reads the audio input into a buffer, and when it receives a MIDI note, plays back the contents of the buffer at the pitch of the note. Checking the Freeze Buffer parameter will stop the plugin reading audio into its buffer while the MIDI note is held, giving the familiar ‘stuck buffer’ effect.

Note that this is not an ‘alpha-version’ but a finished plugin.

Buffer Synth 2

Buffer Synth 2 is a free buffer synth VST plugin developed by ndc Plugs. Compatible OS(s): Windows, macOS.

Buffer Synth 2 is a buffer manipulation plugin, designed to do a number of different things with audio buffers. It could be thought of as a cross between GRM Tools’ Freeze and a wavetable synthesizer, in the way it can be used as either an effect-type plugin, or as an instrument in its own right. To get the most out of it, you’ll need a relatively flexible plugin host – most importantly, one which will allow you to send MIDI data to effects plugins.

Features:

2 separate buffers (88200 samples in size) – can record the incoming audio stream or WAV files can be loaded.

Amp and Mod ADSRs.

2 LFOs.

LP/BP/HP resonant filter.

MIDI Learn.

Synth Mode.

British Valve Custom (BVC)

British Valve Custom (BVC) is a free overdrive and saturation VST, Audio Unit, RTAS plugin developed by Studio Devil. Compatible OS(s): Windows, macOS.

Studio Devil BVC (British Valve Custom) is a guitar tube amplifier modeling plug-in that is designed to mimic the character of “British”-style vacuum tube heads. This virtual tube amplifier processor is based on authentic models of 12AX7A vacuum tube preamps and tube power stages. While primarily intended for guitar amp modeling and direct recording of both electric guitar and bass, Studio Devil BVC excels wherever natural tube overdrive and distortion is needed.

British Valve Custom features the basic controls of a guitar amp: GAIN, TONE, and DRIVE. It is based on the gain structure of popular British Valve (Tube) heads like those made by Marshall with some subtle modifications to give it slightly more gain. The dynamic response and tone is faithful to those from real vacuum tube amps and reacts to your playing style just like the real thing.

Features:

Accurate 12AX7A vacuum tube preamplifier stage emulation with DRIVE control.

Gain structure signal path that’s true to those on vintage tube amp schematics.

Authentic Bass, Mids, Treble, and Presence TONE controls just like those on real tube amps.

Push-pull tube power amplifier model with DRIVE control.

FIR-based speaker/cabinet/mic modeling filter built in for a “miked-up” tone.

4X Up-Sampling Engine with 64-bit Internal Floating-Point Precision.

44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 196kHz sampling rate support.
