dexed ~ Frequency Modulation Synthesizer


Dexed is a multi-platform, multi-format plugin synth that is closely modelled on the Yamaha DX7. Dexed is also a midi cartridge librarian / manager for the DX7.

Features:

  • Multi platform (OS X, Windows or Linux) and multi format. (VST, AU, LV2)
  • The sound engine music-synthesizer-for-android is closely modelled on the original DX7 characteristics.
  • 144 DAW automatable DX7 parameters available from one single panel.
  • Fully supports DX7 input and output Sysex messages; including controller change. This means that you can use this with a native DX7/TX7 as a patch editor and sysex manager.
  • Each operator has a realtime VU meter so you know which one is active.
  • Can load or save any DX7/TX7 sysex programs. It is also possible to save a single program into a different sysex file.

Notable features:

  • Delay time drift, for giving the wet signal a slight wow / flutter effect
  • Adjustable wet level ducking based on the input signal
  • Static, ping-pong, and circular pan modes
  • Drive section based on open-source Airwindows saturation code

CHOW ~ Maximally Truculent Distortion


CHOW is a digital distortion effect designed for maximum truculence, somewhere between a true half-wave rectifier and a noisy vintage compressor. Useful for mixing guitars, drums, even vocals when a heavily degraded sound is desired. Feel free to build and use for your own enjoyment!

Multiply ~ Clear Chorus Effects


Acon Digital Multiply is a free and versatile chorus effect with a unique twist. Each simulated voice is processed with a phase randomizing filter so that unpleasant comb filter effects are avoided. The effect can be used to simulate the effect of several performers playing the same tones simultaneously, to widen the spatial image or to create special effects for sound design. Multiply can simulate up to 6 additional voices and both the pitch and the loudness of the voices can be modulated. There is also an integrated equalizer consisting of low cut, low shelf, high shelf and high cut filters that can be applied to the effect signal. An integrated pre-delay section makes it possible to create modulated and diffuse echo effects.

Argotlunar ~ Granulator VST / AudioUnit


Argotlunar is a tool for creating surreal transformations of audio streams. Specifically, it is a real-time delay-line granulator. It disintegrates an audio stream into short samples (grains). Each grain can have random settings of amplitude, panning, duration, delay, pitch, glissando, filter and envelope. The output of all grains is mixed together into a stream which can be fed back into the main input.

Time-related parameters can be synced to the host tempo, for rhythmic and pulsing textures. Pitch-related parameters can be quantized for harmonic and melodic effects. Feedback can create chaotic, densely layered, and distorted sounds.

Most of the parameters can be correlated. Examples:

  • Filter cut-off correlated with pitch: Higher filter cut-off for grains with higher pitch, and vice versa.
  • Grain duration correlated with panning: Grains with shorter duration panned to the centre of the stereo field, and grains with longer duration panned wide in the stereo field.

OwlPlug ~ Audio VST Plugin Manager


OwlPlug is a desktop application for Windows and Mac that simplifies VST Plugin management and installation. User installed plugins are automatically discovered and new plugins can be installed through Stores. The default store called OwlPlug Central delivers quality plugins made by the community. Any third party plugin distributors can set up a compatible Store and let owlplug interact with it. OwlPlug is still in a beta stage, all kind of feedbacks are welcomed.

FreeAmp ~ Audio Gear Modeler


Sounding good has never been this cheap. Even though FreeAMP may look simple, all the algorithms from our amplifying modeler plugin REAMP are still in there.
