Double Helix Oscillator – overview

Sylvia and I have only had the “Double Helix Oscillator” for a day and a half and we’re really enjoying it. The build quality in their “Stucture 270” Case is first-rate. The “care of design” that’s behind the Double Helix has infused this Module with more functionality than may appear at first glance. Each time we “just want to try a simple Patch”, “hours” just fly by. For us, that’s the sign of a versatile piece of gear.

On June 21st, I sent an eMail to Pittsburgh Modular, asking if there was a Manual for their “Double Helix Oscillator”. This is their reply:

  • The Double Helix is an excellent analog synth voice module. While we don’t currently have a manual for this item available, I’ll be happy to give you a brief walkthrough of its functionality.
  • The Double Helix contains two full range analog oscillators. They can sweep from subsonic LFO range, up past 20 KHz. The first oscillator has 5 waveform options (including a 1 octave down suboscillator and our signature Blade wave) while the second oscillator as 3 waveforms. They both track 1V/O and have various modulation options available.
  • The module also contains an LFO (with Sine, Square, and Random outputs) and an analog noise source
  • The Contour section is where the Double Helix shines. It contains two sections: Timbre and Dynamics. The Timbre section is an analog wavefolder. Basically, it continuously folds the peaks and valleys of the incoming waveform to add complexity and upper harmonics to the sound.  The Dynamics section is based on our Dynamic Impulse Filter module and allows for organic “plucked” percussive sounds
  • Finally, the CV router at the bottom allows for easy control and experimentation with modulation. You can route several modulation sources to various locations simultaneously, which adds even more complexity to the sound.

Although they don’t “technically” offer a “Manual”, they do provide some very helpful information on the Double Helix product page. Here’s the link:

Because Sylvia and I needed a “paper” version of that information, I pulled-out the content from that web page and reformatted it into standard pages… and I allowed for those pages to be on 3-holed paper. (So they could be placed in a 3-ring Binder.

  • Note: If you print those 4-pages as “double-sided”, the holes in the paper will not interfere with the text or images.
