HoRNet ThirtyOne MK2 2.1.0 update

ThirtyOne MK2 combines a spectrum analyzer and a graphic equalizer, both featuring the standard 31 one-third octave bands. These tools are staples in live mixers, and engineers often place them in the master bus. We modeled its behavior after a well-known Italian analog spectrum analyzer and recreated its time response with precision.

The graphic equalizer draws inspiration from analog units, bringing a familiar, tactile feel to your master chain. We carefully replicated the smooth LED lighting by using a gradually increasing current flow. Each LED column follows a 20dB/octave filter, mimicking the original hardware. You can choose between three response speeds—0.25, 1, or 4 seconds—to track fast peaks and average frequencies.

Each LED represents 1, 2, or 3 dB values, with an option for 6dB/LED. When you adjust the resolution, the scale on the left of the display updates automatically. We also included a peak-hold feature for each frequency band, which you can enable or disable. This feature was not present in the original unit.

Beneath the spectrum analyzer, you’ll find 31 sliders that allow you to shape the output and fix any resonances. Each slider controls a standard one-third octave filter, adjustable from -15 to +15 dB. You can also type specific values for each band in the box below each slider.

Additionally, the equalizer features a unique “Auto EQ” function. When you activate Auto EQ, it adjusts the gain for each band based on the spectrum analyzer’s output, optimizing harmonic balance automatically. ThirtyOne MK2 offers three Auto EQ algorithms: Average, Median, and Lucky. The first two rely on mathematical models, while the third was a happy accident that we kept because it sounds great.

• Added Apple M1 support

• Corrected the manufacturer name in AAX

• Fixed slider values that increased when sessions were saved with EQ amounts over 50%

• Resolved an issue where LED bars displayed at full level when no sound was present in certain DAWs
