Double Helix Oscillator

I’ve been wanting to fine-tune the image of the Double Helix Oscillator, that I used in the Patch Chart I created and, today, I finally got around to doing just that. This one is cleaner, more professional looking and contains less clutter… making it easier for everyone to indicate Knob and Switch settings as well as the Patch Cord connections routings.

So the updated Chart for this Pittsburgh Modular module is now in our “Downloads” area and is free to download.

The “Double Helix Oscillator”

Over these last several months, after buying 3 small Synthesizers, Sylvia pointed out that I wouldn’t be satisfied until we got a “Modular”.

  • I thought about it for a while and she’s right. My experience with Synthesizers started in the 70s, when Synthesizers themselves were still evolving. There were only a handful of companies making Synthesizers and “Moog” and “ARP” were the most popular.
  • My first Synth was a very basic Korg. While in High School, I saved-up and bought a “Mini Moog Model D”. About the Time I was getting bored with its limits, I read about a much more flexible, more powerful Synth: the “ARP 2600”. Again, I saved-up some money, sold the Mini Moog and bought a “2600”.
  • In 1972, I took 1 Semester of private Synthesizer lessons from a local college. The Professor in charge of the Music Department told me he went to school with Bob Moog. The Synthesizer in the Electronic Music Lab was a “Studio Moog”, similar to the “Moog System 55”. Here’s the link to that model:
  • www.moogmusic.com/products/modulars/system-55
  • My point is, Sylvia’s observation is correct… Since I came up through “old school”, analog, one-function-per-button, Synthesizers, I wouldn’t be happy until we bought a Modular Synth.

So, after doing a lot of research, we decided to jump in. About a month ago, we bought the 1st piece — the “case”. It’s a “Structure 270”, made by Pittsburgh Modular. Here’s the link to its product page:

Last Saturday, Sylvia and I drove to our local Guitar Center store and bought our 1st Module — the “Double Helix Oscillator”, also made by Pittsburgh Modular. Here’s the link to it’s product page:

When we brought it home, I was just going to try out a few simple things and… almost 4-hours went by… Whoosh! Now THAT’S a sign of an interesting piece of music gear.

  • The keyboard on our ARP 2600 doesn’t work right and we don’t have another keyboard that will send “CV” (Control Voltages) out. So we couldn’t play this new Oscillator with a regular keyboard. However, since we have a “BeatStep Pro” (by Arturia), I was able to connect its “Pitch” output to the Double Helix (to change notes) and the BeatStep Pro’s “Gate” output to the ARP 2600’s “Gate Input” (to fire the Envelope Generators / open and close the sound to the speakers).

Knowing that the “Double Helix” doesn’t have any way of Storing Patches (saving its settings), I spent almost 3-hours today creating a Patch Chart for it. I’ve uploaded it to this Blog and you should be able to download it from the link below. So if you own a “Double Helix”, this Chart may be of some help in keeping track of the sounds you create.

  • A contrasting pen color, such as “red”, works best.
  • For “Knob” settings: simply place a line where the “white line” on the real Knob should be turned to.
  • For “Patch Points” (Jacks): just draw a line from any Patch Point to any other. It’s better if you don’t draw those lines over any other Jacks, Knobs or Switches. If you need to indicate that a Patch Point on the Double Helix is connected to another Module, just end the line below the diagram and add some text explaining where the other end should be connected.
  • For “Switches”: since the Double Helix Switches can be moved to 3 positions, I illustrated those positions with 3 small circles for each Switch. Just fill-in the appropriate circle or draw a line through one of them.

ARP 2600 Patch Chart

Sylvia and I finally got around to writing down the ARP 2600 Patch for the song we finished in February 2016. This song’s initials are “R.L.”. (We’re not releasing the name of this song until the album is available, which is probably several months from now.)

Anyway, these very chaotic, very stressful sounds “start” and “end” that song.

 

 

The 2600’s keyboard wasn’t used for this Patch. After making the above settings, simply turn up the “VCF” and “VCA” Sliders, in the Mixer. For this particular song, we didn’t use Reverb but if you want to use it, this Patch allows for it… just raise the Reverb Sliders to the desired levels.

The “ARP 2600” is a semi-modular, analog synthesizer, which means it doesn’t need Patch Cables, in order to produce sounds. However, when you do use Patch Cables, you can create some very complex sounds.

NOTE: I tried to upload the Patch Chart image between the above paragraphs but WordPress kept showing an “error”. Since Sylvia and I already have a “Weebly” Blog, we added the image there. Here’s the link to that article:
