Synthractive VST VST3 Audio Unit Stereo Subtractive Synthesizer: Leads, Pads, Basses, Keys, Sequences, Atmos Textures, Ambient Soundscapes, SFX (Windows, macOS)
Synthractive is a stereo subtractive synthesizer. Tones are created by subtracting unwanted frequencies, usually harmonics, attenuated by a filter to alter the timbre of the sound. Dialing in a combination of parameters from the oscillators, LFOs, amplitude and filter envelopes, will determine the tone and shape of the sound, which allows to sculpt a wide range of sonic texture.
It can be used to create spacey pads, synth leads, keys, basses, sequences, atmospheric textures, ambient soundscapes and sound effects. Features a collection of 40 presets suitable for many genres and styles of music and flexibility to custom design over a diverse sonic palette.
Features:
- Two Oscillators. Each one features a fine-tuning, pulse width and level parameters, as well as the following selectors:
- Waveform. Selector to switch between sine, sawtooth, ramp, triangle, pulse, white noise and pink noise waveforms.
- Octave. Selector to specify octaves above or below the current octave.
- Note. Selector to switch between 0 to 11 semitones.
- Filter Section. A state variable filter with the following parameters:
- Filter Cutoff. Adjusts the frequency range to contour the sound, add or regulate brightness.
- Filter Resonance. Slightly emphasize or suppress portions of the signal above or below the defined color/tone frequency.
- Keyboard Tracking. The Key Tracking knob position subtly modulates the cutoff frequency.
- Filter Type. Switches the filter between lowpass, highpass, bandpass, or band-rejection filter types, offering a simple and effective tone control to shape and color the sound source.
- Filter Envelope. This section provides control of the filter cutoff frequency over time, with ADSR parameters: attack time, decay time, sustain level, release time plus a level knob that defines the envelope overall level.
- Amplitude Envelope. This section controls the volume or amplitude of the sound with independent control over each ADSR stage with an amplitude envelope overall level.
- Two Low-Frequency Oscillators. These parameters apply LFO modulation of various aspects of the audio signal to apply effects such as vibrato or tremolo.
- LFO Rate: Controls gradual changes to the pitch of notes or the filter cutoff frequency.
- LFO Depth: Controls the amplitude of the LFO. With a lower setting, the resulting modulation is subtle, while a higher depth will result in a much more extreme effect.
- The following parameter settings adds motion or variability to sounds:
- Waveform. Selector to switch between sine, sawtooth, ramp, triangle, pulse, white noise and pink noise waveforms.
- Source. Combo box to switch between LFO 1, LFO 2, Filter Envelope, Velocity, Aftertouch and Modulation Wheel.
- Destination. Selector to switch between Cutoff, Pulse Width, Pitch and Volume modulation.
- Invert. Sets the LFO shape to be a positive or negative envelope. Off applies a positive envelope shape. On applies a negative envelope shape.
- Stereo Reverb effect. Ambience spread brings a sense of spatial depth and width to sound, from small to huge sounding spaces.
- Stereo Delay effect. Stores the input signal and plays it back after a certain amount of time, creating from a subtle echo to a pronounced blending of previous sounds with new sounds. Improves the stereo image by adding a slight delay to one of the channels. Parameters includes a time knob, to vary the delay time dynamically and a feedback or regeneration control.
- Preset Manager. Built-in browser to load and save presets and banks.
