DD Tremolo
Key Features
- Sine, sawtooth and square modulation waveforms offer smooth, ramped or abrupt volume movement.
- Optional tempo synchronization locks the pulse to musical divisions.
- Frequency mode sets the modulation rate independently of the host tempo.
- Bipolar depth control adjusts modulation intensity and inverts the waveform.
- Inverting the sawtooth waveform changes the direction of its ramp.
- Soft bypass crossfades between processed and unprocessed signals to reduce switching clicks.
Description
DD Tremolo is a volume modulation effect from Dead Duck Software's Free Effects collection. It adds repeating changes in level to audio, with a choice of three waveforms and optional synchronization to the host tempo.
Choose sine for smooth pulses, sawtooth for a ramped pattern, or square for abrupt changes in level. The rate runs from 0.5 Hz to 20 Hz in frequency mode, or follows musical divisions from 2/1 to 1/32T when sync is enabled.
A bipolar depth control sets the amount of modulation and can invert the waveform. With the sawtooth setting, that inversion also changes the direction of the ramp, giving you another rhythmic contour without changing the rate.
The compact control set makes DD Tremolo useful for adding steady movement to sustained instruments or turning a part into a more pronounced rhythmic pulse. Plugins4Free users have praised its straightforward interface and synchronization, although one commenter wanted more control over the LFO shape.
The current Free Effects bundle includes Tremolo as an individual Windows DLL for 32-bit and 64-bit VST2 hosts. The developer's documentation identifies the effect and directs visitors to KVR Audio for the free bundle download.
Frequently Asked Questions
Can DD Tremolo follow the DAW tempo?
Yes. Enable Sync to use tempo-based divisions from 2/1 to 1/32T; with Sync off, the rate is set in hertz.
Which modulation waveforms are available?
The current developer documentation lists sine, sawtooth and square. Negative depth inverts the selected waveform and changes the direction of the sawtooth ramp.
Where is DD Tremolo downloaded?
Tremolo is included in the Free Effects collection. The developer directs users to KVR Audio for the bundle download.
Does it work on macOS?
The developer supplies the Free Effects as Windows DLL files for 32-bit and 64-bit VST2 hosts. The documentation does not list a native macOS version.
