WOV

This audio effect plugin transforms sounds into a wide range of textures, from tremolo to glitchy stutters. It offers deep customization of rate, depth, and waveform, with an eight-step sequencer for accents. Requires an AUv3 host app to function.

WOV for iOS is an AUv3 effect for making a wide range of textures out of your sounds – from familiar tremolo waves to glitchy stutters and everything in between.  WOV lands on iOS with an injection of inspiring presets by Richard Devine and Stèv! *** Please note: WOV is an Audio Unit extension (AUv3) – it only works in an AUv3 host app like Garageband, AUM, Cubasis, Modstep, Beatmaker 3, etc... *** HOW IT WORKS / DESCRIPTION The Rate Section This section determines the rate or speed at which WOV operates. Rate can either be assigned in Hz, or in fractions of a beat in sync with a hosting app – to switch between Hz and sync modes, use the switches at the bottom center of WOV. It’s easy to set up a static rate for WOV and leave things at that – but WOV has much more to offer! To the right of the Rate control, the bipolar Response knob sets the sensitivity with which WOV’s rate will either slow down or speed up depending on the volume of the incoming signal. The bipolar Variation control further introduces randomized amounts of variation to the rate – at its extremes going as far half the rate (knob to the far left) or twice the rate (knob to the far right). The Depth Section Depth sets the amount of modulation over the dry signal – to the left and it’s more subtle, all the way to the right and WOV will act as a repeating gate. Silence introduces more randomness to the plugin, increasing the likelihood that the amplitude will be zero for some cycles. The Waveform Section The waveform of a tremolo effect is essentially its repeating envelope. Classic tremolo effects offer stock waves – WOV, being a K-Devices product, is much more customizable! The Wave knob morphs between a quasi-sine shape (far left) and a slightly rounded-off square shape (far right). Peak acts as a kind of attack control for the waveform – far left for a sharp attack, or far right to reach the peak more gradually. Finally, the Warp knob allows you to either squeeze or expand the waveform, affecting the length of each sound. When the Wave control is set to a full square, Warp acts as a duty cycle/pulsewidth control. The Accents Multislider The eight-step sequencer uses a multislider to set the relative accent value for each beat of the rate. The slider adjusts between two and eight steps in length, and a button offsets the accents going to the right channel one step over from the left (note that this requires Stereo to be enabled). — Get Wide WOV can either preserve the stereo placement of its input signal, or it can add stereo offset to the output signal. Enabling the Stereo switch directly affects the Response, Silence, and Sequencer for a wider sound. Go By Feel As part of encouraging more musical and creative applications of WOV, in addition to using symbols for controls, the controls in WOV do not have individual readouts. We encourage you to let your ears determine the right knob positions whenever you can! If you’d like a precise readout, however, you can see/edit it by clicking on any parameter and looking in the upper-right corner of WOV. Icons By default, all labels are graphical – for text labels, click the symbols/text label switch in the lower-right had corner.

BLEASS Flanger harnesses the sonic characteristics of classic flanger effects and brings them fully up-to-date with a pair of flexible LFOs, variable modulation routing, an envelope generator and beat synchronisation. Classic flangers are a delay-based effect, and modulate the delay time to create the distinctive, repetitive flanged sound. But with BLEASS Flanger, multiple modulation sources are combined to create detailed, complex and evolving timbral movement within your sound. The addition of an envelope generator, which is triggered by the incoming signal, adds an additional dimension to the flanger effect, making it sensitive to the dynamics and nuances of your performances. The second LFO can take the sonic possibilities further still, with the option for it to modulate the delay’s feedback strength or stereo width. The tonal character of the effect can be controlled easily thanks to the multi-mode input filter, whilst the ability to synchronise the LFOs to the beat of your music allows you to explore completely new rhythmic and evolving effects. BLEASS’ trademark interface design ensures this powerful collection of tools are both easy and fun to work with, so you can harness their sonic versatility without ever hindering your musical creativity. And with super-efficient CPU usage, and compatibility with all major hosts and DAWs on desktop, iPad or iPhone, BLEASS Flanger is the only flanger you will ever need.
