What BLEASS Dragonfly does
Instead of a plain fixed-rate tremolo, Dragonfly takes its rate from the material itself, so a synth, voice or external bass line can be made to pulse in correspondence with its own frequencies.
Source selection sits at the start of the chain. The pitch tracking module can read the input audio track itself in Self mode, read a sidechained signal, or follow MIDI notes so the tremolo syncs to their frequencies with accuracy. Manual mode sets a fixed frequency with the Rate knob and the depth with the Amplitude knob. In MIDI mode the amplitude follows note velocity, in Self and Sidechain modes it matches the amplitude of the tracked signal, and a Source Channel control chooses the channel.
Once the source is set, the Dragonfly stage refines the result with Fine, Factor, Smoothness, Stereo, Attack and Release settings. The final tremolo rate is mirrored by the flapping wings drawn on the interface.
Key features
- Pitch tracking sources. The pitch tracking module reads the input audio itself in Self mode, a sidechained signal, or MIDI notes, and the tremolo rate follows the detected frequency.
- Manual rate and amplitude. In Manual mode the Rate knob sets a fixed tremolo frequency and the Amplitude knob sets the depth of the effect.
- Velocity-driven amplitude. In MIDI mode the tremolo rate corresponds to incoming notes and the tremolo amplitude corresponds to note velocity.
- Fine-tuning controls. Fine, Factor, Smoothness, Stereo, Attack and Release adjust the shape and movement of the tremolo after the source is chosen.
- Wild mode and Wildness. Wild mode applies a waveshaper for subtle saturation, and the Wildness control sets how much complex waveshaping is applied.
- Source Channel control. A Source Channel control sets which channel of the input the pitch tracker reads.
Compatibility
Minimum requirements are macOS 10.9 and Windows 8, and native support for Apple Silicon processors is listed. A trial is available.
