SineVibes had introduced Torsion, a new monophonic Audio Unit synthesizer that offers multiple synthesis technologies and modulation sources.
Torsion’s sound structure is similar to a traditional subtractive synthesizer – three oscillators going into a low-pass filter and into an amplifier. But Torsion’s oscillators are different: they produce simple additive waves based on just a few partials, which are then enriched with spectral content using a technique called waveshape modelling (which literally “curls” the wave in real time).
To further spice the sound up, there is a ring modulator and an audio-range oscillator for filter FM.
Torsion features as many as four separate LFO generators – one for each oscillator and one for the filter and output amplifier. In addition to precise synchronisation, each LFO cycle can be self-randomised, which makes the modulation rhythmical yet non-repetitive. There are also two AHDSR envelope generators, as well as a two-dimensional chaos oscillator.
The interface of Torsion is designed with high-contrast, colour coded elements, which lets you operate the instrument intuitively. It also includes graphic representations for every building block – oscillator waves, LFO phases, envelope shapes and filter spectrum all change as you modify them.
- Three oscillators each with four basic additive waveforms and four waveshape models.
- -24 dB/octave resonant low-pass filter.
- -12 dB/octave high-pass filter.
- Ring modulator.
- Modulation oscillator for low-pass filter FM.
- Four tempo-synchronised LFO generators with four waveforms and per-cycle randomisation.
- Two AHDSR envelope generators.
- Two-dimensional chaos modulation generator based on Lorenz attractor.
Torsion is now available for $49. See the SineVibes site for audio demos and more details.
