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.

Highlights
  • AUv3 audio effect
  • Creates sound textures
  • Customizable rate and depth
  • Morphable waveforms
  • Eight-step accent sequencer
  • Stereo widening effects

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.

About

BLEASS Dragonfly

This audio effect plugin offers a unique approach to tremolo, allowing music producers to add dynamic modulation to synths, vocals, and melodies. It syncs tremolo effects with input frequencies, MIDI notes, or sidechained signals for creative sonic textures.

Highlights
  • Pitch tracking for self or sidechain modes
  • MIDI input for precise triggering
  • Manual rate and amplitude control
  • Adjustable smoothing, stereo, attack, and release
  • Wild mode for saturation and waveshaping
  • Animated visualization of effect rate

BLEASS Dragonfly is a completely new approach to tremolo effect which brings new sonic possibilities to all music producers. Make your synths, voices or any melody “vibrate” in correspondence with its own frequencies, or with external basses and leads! Just like in Billie Eilish’s song “Xanny”, Dragonfly helps you achieve the same effect as when the voice gets modulated by a heavy bass. BLEASS Dragonfly automatically syncs the tremolo effect applied on a track using various triggers: First, you can use the pitch tracking module on either the input audio track (“self mode”) or a sidechained audio track (“sidechain mode”). You also can use the midi input to trigger Dragonfly with accuracy: the tremolo will automatically sync with the notes’ frequencies. Finally, a manual mode allows you to set a fixed frequency. Then you can finetune your settings by adjusting the fine, factor, smoothness, stereo, attack & release. The “Wild” mode applies a waveshaper to the signal to produce a subtle saturation. The final tremolo effect rate is mirrored by the flapping wings of the Dragonfly. BLEASS Dragonfly is also available for Mac & Windows (AU / VST3) https://www.bleass.com/dragonfly/ ________________________________________________ Technical description: SOURCE stage: - MANUAL: Tremolo rate is set by the Rate knob. Tremolo amplitude is set by the Amplitude knob. - MIDI: Tremolo rate corresponds to the rate of the lowest MIDI note received by the plugin. Tremolo amplitude corresponds to the velocity value of this note. - SELF: Pitch tracking on the input signal gives the tremolo rate. Tremolo amplitude matches the input signal’s amplitude. - SIDECHAIN: Pitch tracking on the sidechain signal gives the tremolo rate. Tremolo amplitude matches the sidechain signal’s amplitude. - SOURCE CHANNEL: Sets the channel to be analysed for SELF and SIDECHAIN modes. - AMPLITUDE: Sets tremolo amplitude in MANUAL mode. - GAIN: Sets the input gain in MIDI, SELF and SIDECHAIN modes. DRAGONFLY stage: - RATE: Sets tremolo rate in MANUAL mode. - FINE: Offsets the detected pitch value by +/- 0.5 semitone in MIDI, SELF and SIDECHAIN mode. - FACTOR: Detected or set rate is multiplied by this factor to give the final tremolo rate. - SMOOTH: Sets the smoothing duration of rate variations. - STEREO: Sets phase difference between left and right channels. - ATTACK: Attack duration of the effect. - RELEASE: Release duration of the effect. - MODE: SIMPLE is a basic tremolo. WILD uses complex waveshaping for warm and saturated effect. - WILDNESS: Sets waveshaping strength in WILD mode. - VISUALISATION: Dragonfly wings are animated to match the rate and amplitude of the effect. Green label on the left indicates the input MIDI note and rate. Blue label on the right indicates the applied MIDI note and Rate. MIX stage: - GAIN: Output gain of the effect. - DRY/WET: Dry/wet balance. NOTE: This is an AUv3 effect which needs a compatible host that ideally offers audio sidechain or MIDI FX routing (such as AUM, Cubasis 3 or Logic)
