Helpful Articles On Learning About Synthesizers

4/13/2019

I just wanted to pass along a few more resources which provide helpful information on "what" Synthesizers are and "how" the various components can be used.

Before I do that, I want to mention something I haven't heard anyone talk about… "Patch Cables" and, specifically, "how many" Patch Cables should you buy?

There is no mathematical formula to this question. However, the rule-of-thumb would be "more is better". My very loose guideline for "how many" to buy would be:
  • 5-Cables for your first Module
  • Then 2 Cables for each Module you purchase after that.

Again, this is not a locked-in-stone way of approaching this.

Yes, you can count the "Patch Points" (Cable-connection "holes" / "sockets") on each Module, and buy THAT MANY Cables, but that doesn't really work. In most cases, buying that many Cables would simply give you a LOT more Cables than your Synthesizer would ever be able to use. ​
  • For example, Sylvia and I have the "A-143-2 Quad ADSR" by Doeper. It contains 24-Patch Points (jacks) — 8 "Input" Points and 16 "Output" Points. If you purchased 24-Patch Cables you'd have way more Cables than this Module can possibly use. (Remember, a "Patch Cable" contains 2-Jacks [connectors] — one on each end.) With 24-Patch Cables, you'd have 48-Jacks. If you only purchased "8" Cables, to cover the number of "Inputs", there may be times when you'd want 4 or more Cables to create a more complex Patch.
  • Here's the link for more information about this Doepfer Module:
  • www.modulargrid.net/e/doepfer-a-143-2

Right now, we have 61-Patch Cables… BUT, combined, our 3 Synthesizers (ARP 2600, Behringer Neutron and a partially completed Eurorack Synth) contain 280-Patch Points. So, of course, we still have "Patch Cables" on our "buy more Eurorack items" list.
  • We've been buying the "LMNTL" brand Cables.
  • Here's the link:
  • www.perfectcircuit.com/catalogsearch/result/?q=lmntl%20cables
  • (Sylvia and I aren't associated with "Perfect Circuit" or "LMNTL" in any way. I've only linked to the Perfect Circuit website because that's the only place we've been able to find these Cables.)

Patch Cable Length
In a previous Post, I included a link to a "helpful tips" video by Robin Vincent.
Here's that link:
www.youtube.com/watch?v=l7LFURMEs8Q

One of the things he learned, when performing Live with his Eurorack Synthesizer, is that he used short Cables whenever possible. The downside to this, he discovered, was that these Cables not only blocked the Modules they crossed (which they always do) but their tightness made it difficult for him to easily get his fingers through to the Knobs and Switches.

Instead, it may sometimes be a good idea to use longer Cables and have them droop down and away from most of the Modules you'll be using in that Patch.

Patch Cable Colors
When I took Synthesizer Lessons in the 70s, Patch Cables were only available in "gray". (That's all "I" saw, anyway.) Today, there are LOTS of colors to choose from and there are 2 types of Synthesists, regarding which colors to buy:
  • Some people use only 1-color, because it looks good when you're Patching, or
  • Use multiple colors because it's much easier to trace the signal-flow in your Patch.

This really comes down to "personal preference". For "us", even though Sylvia loves "Purple", we do our best to select as many different colors for each Patch as we can.

When using a single color for an entire Patch, it can be continually frustrating, when you have to keep following and re-finding where each Cable goes, just to tweak something "quickly".
  • Our "partial" Eurorack Synthesizer currently contains 10-Modules. Even so, any Patch we create could easily use 10-to 20 or more Patch Cables… and if we connect that Patch to an external Synth, like our ARP 2600 or Behringer Neutron, we'll use several MORE Cables.

It's "sometimes" possible to use one color for "Modulation" (Envelopes, LFOs, etc.) and another color for "Audio". Let's say "Red" for Modulation and "Green" for Audio. However, there are 2 problems with this approach:
  • Even with "2" colors of Patch Cables, it's still going to be VERY difficult to "quickly" locate the Module, and the "Knob" on that Module, that you'll need to turn in order to change the sound the way you want. (For example: Should you be changing an "LFO" or the "Envelope"?)
  • Let's say you've connect a Red "Modulation" Cable from an LFO to a Multiple — so it can be split to more than 1 destination. You then connect another Red Cable to an Oscillator, in order to Modulate its Frequency — giving it a moving "wow" affect. Then you change your mind and decide to use another Oscillator's audio output to Modulate that 1st Oscillator — now giving it a distorted sound. Under your "Red-Green guidelines", you'll have to remove those Red Cables and replace them with Green ones, when you could have simply moved 1-end of 1-Cable to the Oscillator's audio output.

Synthesizer Resources
Here are a few articles and videos where you can find a lot of helpful information on understanding Synthesizers (in no particular order):

​This article is titled: "What are CV, Gate and Triggers, and how do they relate to semi-modular synthesis?"
www.musicradar.com/how-to/what-are-cv-gate-and-triggers-and-how-do-they-relate-to-semi-modular-synthesis

The following article is titled: "Synth Terminology And Basics for Beginners". It covers:
  • Subtractive Synthesis
  • The "Oscillator"
  • Analog versus Digital versus Hybrids
  • Filters and Cutoff
  • Envelopes
  • Modulation
  • FM Synthesis

​Here's the link to that article:
ask.audio/articles/synth-terminology-and-basics-for-beginners

Here's the link to a Robin Vincent video titled: "Molten Modular 15 - Discovering oscillators with the Make Noise STO".
www.youtube.com/watch?v=LUrtCf5i7ng

Here's another good video by Robin Vincent. This one's titled: "Molten Modular 24 - Discovering Envelopes featuring TINRS Edgecutter".
www.youtube.com/watch?v=2KOP1HqNbtY

Here's Robin Vincent's main YouTube Channel:

Modular Grid: The best place to go for "all things Eurorack related".
www.modulargrid.net/e/modules/browser?SearchName=&SearchVendor=&SearchFunction=&SearchSecondaryfunction=&SearchTe=&SearchTemethod=max&SearchBuildtype=&SearchLifecycle=&SearchSet=&SearchMarketplace=&SearchIsmodeled=0&SearchShowothers=0&SearchShow1u=0&order=newest&direction=asc

Of course there are LOTS of other sources of information online. Even with all the information and links I've provided here, there are still a few facets of Synthesizers which were not mentioned in the above articles and videos, such as:
  • Granular Synthesis,
  • Wavetables,
  • Formants,
  • Karplus Strong,
  • Sequencers,
  • Logic Modules, etc.
I simply listed them, in case you'd like to explore these subjects further on your own.
