A set of beefy, analogue oscillators paired with voltage controlled shape contouring, deep modulation, and a performance ready voltage controlled modulation matrix create a dynamic, analogue waveform playground.
At the core of the Double Helix are two, wide range, precision oscillators. The primary oscillator includes a full compliment of waveforms and multiple modulation options. The Secondary oscillator offers a more focused set of waves and frequency modulation. Both oscillators reach deep into LFO range and can be used as voltage controlled modulation sources.
The contour section of the Double Helix Oscillator features a highly tuned wavefolder paired with Pittsburgh's exclusive dynamic impulse low pass gate. The contour signal chain starts with a two channel mixer. This allows multiple waveforms or multiple oscillators to be combined before passing though the contour section. The first half of the contour section is a voltage controlled, 6 stage wavefolder used to add odd harmonics to the incoming waveform. The timbre and timbre CV controls set the density and amplitude of the folds. When processing a sine wave, the wavefolder creates a spectral change from zero harmonics to square, with an infinite harmonic series.
The second half of the contour section is a dynamic impulse low pass gate. The effect of the low pass gate is similar to pairing a low pass filter and VCA together. As the dynamics control is opened, the filter adds harmonics and the VCA increases the amplitude of the waveform. As the dynamics control is closed, the filter removes harmonics and the VCA decreases the amplitude of the waveform. This pairing mimics how sound behaves in the real world creating a more naturally tonal response. The impulse input adds the ability to strike or ping the low pass gate circuit creating a very organic, percussive sound. The decay time of the impulse input is set by the dynamics response control allowing the strike to be tuned to a specific musical context.
The modulation section includes an LFO offering simultaneous sine, square, and random waveforms. A noise source is also available for audio or modulation use.
A pair of voltage controlled routers manage all the CV inputs creating a dual, voltage controlled modulation matrix perfect for complex signal paths, experimentation, and live performance. The matrix consists of two voltage controlled amplifiers designed to control the modulation amount inputs that can be routed to any of the Double Helix CV inputs. Each of the CV inputs can be switched to channel a, bypass, or channel b and mixed with a dedicated CV input.
