Discord4 vs BLEASS Dragonfly
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
- 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 latest version of our most popular and long-lived product, our Discord stereo pitch shifter. Originally modeled from the H910, Discord has long since become its own effect and a studio standby, and this version includes major additions to further stretch its capabilities. This application includes a stand-alone version (with Inter-App Audio) and an AUv3 effect for use in hosts that support that format, such as Beatmaker 3, AUM, Cubasis, and Garageband. A full PDF manual is available at the Audio Damage website. Discord4 consists of three separate algorithms: a "vintage" mode (the original Discord algorithm, modeled on the Eventide H910 and H949), a "clean" mode for more modern shifting sounds, and a "granular" mode for experimental effects. Each mode has its strengths, depending on the input material, and Discord3 has a broad palette of capabilities as a result. The P1 and P2 algorithms have full control over the buffer (window) size of the shift effect, for fine tuning the shift to the input signal, or for stranger sound effects. At the extremes of the six-octave shift range, some truly strange aliasing and artifacts can be had with this control. Discord4 retains its pair of tempo-synced delays and bandpass filters from previous versions, and adds a reverb in the feedback loop (for easy access to "shimmer" effects). We have also replaced the modulation sources from the original with our all-new FLFO (Flexible LFO) design. Panorama controls are included to control the stereo width of the wet signal. Finally, soft saturation and limiting have been added or improved throughout the signal path, for an overall improved sound and added vintage-style warmth, and to allow for extreme feedback experiments without fear of overloading your DAW's channel. Features • Pitch Shifting: Discord4 contains a pair of shifters with three separate algorithms (Vintage, Clean, and Granular) for different styles of pitch shifting. • Buffer Size Control: The P1 (Vintage) and P2 (Clean) algorithms have a Buffer Size control, from 32 to 2048 samples, for fine-tuning the pitch shifting effect. • Delay: Tempo-synced or free-running delays with feedback, cross-feedback, and a sophisticated bandpass filter. • Reverb: A simple stereo reverb is added to the feedback path, for "shimmer" effects and further sound exploration. • Modulation: Two of our new FLFO (Flexible Low-Frequency Oscillator) with tempo sync and an arbitrary waveform, capable of a nearly infinite number of modulation shapes using only three controls. • True Stereo Operation: Discord4 has a true stereo signal path, with entirely independent control over each side, finishing with panorama settings for stereo width. • MIDI Note Control: Six octaves of pitch-shifting can be controlled with MIDI note input. • All-New GUI: Vector-based resizable user interface. • Presets: Cross-platform XML-based preset manager.
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.
- 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)

Verdict
Discord4 and BLEASS Dragonfly both sit at 4.7 stars, but that hides the real split: 100% of BLEASS Dragonfly's written reviews are positive against 61% of Discord4's. BLEASS Dragonfly also leads on price ($7.99 vs $8.99). Discord4's advantage is update cadence (every 10 months vs every 24 months) and iOS requirement (9.3 vs 12.0). On rating, ratings volume, ads and in-app purchases there is nothing between them.
