About

Discord4

This stereo pitch-shifting delay app offers three distinct algorithms for vintage, clean, or experimental granular effects. It features tempo-synced delays, a reverb in the feedback loop, and flexible LFO modulation for extensive sound design. Control pitch shifts with MIDI and fine-tune effects with buffer size adjustments.

Highlights
  • Three pitch-shifting algorithms (Vintage, Clean, Granular)
  • Tempo-synced and free-running delays
  • Reverb in feedback loop for shimmer effects
  • Flexible LFO modulation
  • MIDI note control for pitch shifting
  • True stereo operation with panorama controls
  • Resizable vector-based GUI

Discord4 is the Audio Damage stereo pitch shifter, in its fourth generation. Each channel has its own pitch shifter, delay, bandpass filter, and feedback, and every repeat runs back through the shifter, so the same effect can double a vocal, stack fifths into an arpeggio, or send echoes spiraling up or down. Three engines set the character. Vintage is modeled on the H910 and H949 and has their grainy, glitchy character. Modern is cleaner and more transparent. Both have a buffer control from 32 to 2048 samples that changes the character of the shift. Granular cuts the signal into grains from 15 to 100 ms long, with an interval control and a Chaos knob that scrambles them, for anything from soft clouds to complete destruction. Detune the two sides a few cents in opposite directions over a short delay for a wide doubler. Set one side a fifth up, sync the delays, and raise the feedback so each repeat climbs another step. Keep the reverb in the loop for shimmer, then hit Freeze to hold a pad under the part. Turn on MIDI Shift to play harmonies from a keyboard, or ride the pitch wheel for bends. • Three pitch-shift engines: Vintage, Modern, and Granular • True stereo: each side has its own shifter, delay, filter, feedback, and pan, or link them so the right follows the left • Up to three octaves up or down, set by the cent or locked to semitones • Delays up to two seconds per side, free-running or tempo-synced, with feedback and cross-feedback • A bandpass filter in each feedback path, set from an XY pad • A stereo reverb inside the loop, with Freeze to hold the tail indefinitely • Saturation in the loop to keep runaway feedback in check • Two flexible LFOs for pitch, delay time, and filter frequency, shaped by Wave, Skew, and Warp, free from 0.01 to 14 Hz or synced to tempo • MIDI Shift: play the shift amount from a keyboard, with pitch bend, in hosts that send MIDI to effects • A preset browser with folders and favorites, and 50 factory presets from everyday doubling to the thoroughly strange Discord4 runs as an AUv3 plugin inside any compatible iOS host, including AUM, Cubasis, Drambo, and apeMatrix, and as a standalone app with background audio for live input. It is also available for macOS, Windows, and Linux as a desktop plugin. Requires iOS 16 or later. An AUv3 host app is recommended. No subscriptions. No accounts. No nonsense.

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)
