HoRNet AutoGain Pro MK2 2.0.9 update

We are pleased to announce the release of AutoGain Pro MK2 v2.0.9, a maintenance update for our advanced gain automation utility. This latest version continues to build on the powerful and flexible features of AutoGain Pro MK2, a tool designed to give you full control over volume automation, whether you are working in stereo or mid/side (M/S) mode. With new fixes and refinements, it remains one of the most versatile dynamic processors available.

AutoGain Pro MK2 is a flexible volume automation processor that takes gain control to the next level. It is based on the same highly accurate DSP core as our original AutoGain Pro, but it significantly expands the processing capabilities. Instead of one detector and one processor, you now get two independent detectors and two separate gain processors, providing a level of control and flexibility that’s unmatched in standard gain automation tools.

When the plugin is set to “classic” mode, it emulates the behavior of the original AutoGain, giving users that familiar response and simplicity. However, the real power of AutoGain Pro MK2 lies in its ability to operate in both stereo and mid/side (M/S) processing modes. This makes it suitable not only for basic gain leveling tasks but also for creative sound shaping, stereo field manipulation, and transient control.

Each of the two detectors can analyze different aspects of the signal. They can pull information from five different sources, including internal signal paths and external sidechain inputs. This means you can use one detector to follow the dynamics of the kick drum, for example, and another to follow the snare or vocals. Each processor can then choose which detector to follow, making it possible to create highly adaptive and responsive automation effects.

This dual-detector/dual-processor architecture is what makes AutoGain Pro MK2 far more than just a volume rider. It can behave like a compressor, a transient shaper, or even an envelope follower, depending on how you configure the controls. With the right settings, you can tighten up drum transients, subtly control vocal levels, or create special effects that react dynamically to other tracks in your mix.

Each detector features standard dynamics parameters such as attack and release, allowing you to tailor how quickly it responds to the input signal. These are complemented by high-pass and low-pass filters, so you can focus the detector on a specific frequency range—perfect for isolating vocals, basslines, or percussive elements. You can also control the level of the detector signal itself, giving you an additional way to fine-tune how much it influences the processor’s behavior.

The signal flow works like this: Each detector generates a control signal based on the source you assign. That signal is then routed to one of the processors, where it is compared to the input signal. The processor then computes the required gain adjustment to match the desired dynamic behavior. The final result is a dynamically adjusted output that remains transparent and musical.

To give you even more control, AutoGain Pro MK2 includes additional shaping tools such as the “scaler” knob, which adjusts the intensity of the applied gain. You can also set boundaries using the “max gain” and “min gain” parameters, ensuring that the automatic gain never exceeds your specified limits. This makes the plugin ideal for tasks that require both precision and safety—such as mastering or dialog leveling in post-production.

Version 2.0.9 brings important maintenance improvements:

• Fixed an issue with M/S encoding and decoding on Windows: This resolves a problem some users experienced when using mid/side mode, ensuring accurate signal handling and channel separation across platforms.

• Removed 32-bit support on Windows and macOS: As most modern DAWs and systems are now 64-bit only, we have removed legacy 32-bit plugin formats to streamline compatibility and ensure better long-term performance.

These changes make AutoGain Pro MK2 more stable, modern, and efficient while preserving all the features that have made it a favorite among producers, engineers, and sound designers.

If you already own AutoGain Pro MK2, this update is free and available now from the user area on our website. You can also download it via HoRNet DoIn, our convenient downloader and installer tool, which ensures you always have the latest versions of your plugins with minimal hassle.

Whether you’re working in the studio, producing a podcast, mastering a record, or performing live, AutoGain Pro MK2 gives you an intelligent and intuitive way to control dynamics. Its unmatched flexibility and precision make it suitable for a wide range of audio tasks, from transparent volume automation to deep creative shaping.

We designed AutoGain Pro MK2 not just as a tool, but as a versatile audio partner that adapts to your workflow. By allowing you to build complex gain response chains with just a few clicks, it brings the power of dynamic control into any production environment—without sacrificing usability or CPU efficiency.

We encourage all users to update to version 2.0.9 to take advantage of the improvements and maintain compatibility with modern systems. As always, if you have questions or need support, our team is here to help.
