Bedroom Producers Blog proudly releases HY-ESG, a freeware Euclidean sequencer gate developed by our friends at HY-Plugins.
HY-ESG is a gate sequencer (aka a trance gate effect) with a twist. It uses a Euclidean sequencer instead of the standard step sequencer seen in most other trance gate plugins. You’ll probably find that HY-ESG is more fun and inspiring to use than your current favorite gate sequencer effect.
But what does Euclid, an ancient Greek mathematician from mid-4th century BC, have to do with step sequencers and trance gates?
I asked myself the same question when Mr. Tadashi Suginomori, the DSP programming mastermind behind HY-Plugins, reached out and told me that the forthcoming HY-ESG plugin will be released for free on Bedroom Producers Blog.
Happy about the news, I was eager to learn more about Euclidean sequencers (because my knowledge at the time was non-existent). As per usual, the Internet provided all the answers in a matter of minutes.
A Quick Introduction to Euclidean Sequencers
The Euclidean algorithm is a mathematical method for finding the greatest common divisor of two numbers. It appears in Euclid’s Elements (a textbook from 300 BC) and is actually one of the oldest mathematical algorithms in everyday use.
More than two millennia later, Mr. Godfried Toussaint (1944 – 2019) discovered that the Euclidean algorithm can generate rhythms. He described the process in a paper titled “The Euclidean Algorithm Generates Traditional Musical Rhythms,” published in 2005.
Fast-forward to the age of VST plugins and Max for Live devices, and you won’t have a hard time finding quite a few musical sequencers that utilize this concept, including HY-Plugins’ very own HY-RPE2.
Another one of those plugins is the brand new HY-ESG gate sequencer by HY-Plugins.
A Quick Introduction to HY-ESG
HY-ESG is a freeware trance gate programmed by HY-Plugins, the developer behind popular VST plugins like HY-Poly and HY-TP2, to name just a couple. The effect is available for free download exclusively here at Bedroom Producers Blog.
At its core, HY-ESG is a gate sequencer. Its sequencer module controls the gate effect, which uses an ADSR envelope to modulate the volume. It can add rhythm and movement to static sounds.
To make things more interesting, HY-ESG substitutes the standard grid-based step sequencer with a Euclidean sequencer, unleashing the age-old rhythm-generating powers of ancient Greek mathematical algorithms in the comfort of your DAW. Πῦρ!
On a more serious note, let’s take a closer look at HY-ESG’s interface.
Located on the left is the Euclidean sequencer module, controlled by the set of knobs on the right. The user can define the number of steps and pulses, as well as the sequence’s duration and direction. The sequence can be rotated, randomized, or restarted at any step.
The Gate section is where you’ll find the ADSR controls for the volume envelope. This is where you’ll adjust the shape of the triggered steps, making them snappier or duller. On the right, the user can change the output gain and adjust the mix knob.
The Modulation section is where things can get crazy, in the best of ways. HY-ESG offers three modulation sources, each capable of running in LFO or S&H modes. These can modulate the ADSR envelope, the mix knob, and yes, the sequencer controls, too.
Use one LFO to modulate the number of steps while another LFO modulates the pulses and the S&H generator controls the mix knob.
Say ἴθι χαίρων to monotonous sounds and Χαῖρε to ever-evolving complex rhythms that will spark a philosophical debate about the creative limitations and other negative implications of grid-based sequencers in modern-day music production software.
Back to being serious, HY-ESG is a unique, versatile, and easy to use gate plugin. Load it as an insert on an audio channel and explore the endless rhythmic effects it can create.
