Kazrog Plugin Updates - October 27, 2026

We're excited to announce a round of FREE updates for 14 Kazrog plugins, along with a brand new product release. Just open the Kazrog Plugin Manager to download the latest updates now.

Here's what's new...

Introducing Vac Rac TSL

The newest member of the Kazrog family is here. Vac Rac TSL is the official emulation of the Inward Connections Vac Rac*, a hand-built, two-channel tube optical compressor. Developed with Steve Firlotte of Inward Connections, it includes three voicings modeled from units owned by Devin Powers and Ross Hogarth, a transformerless path modeled from JJ Blair's original modular Vac Rac TLM-1, plus THD, mid/side and parallel mix controls. It's available now for a launch price of $49.99 (regularly $79.99).

A New Oversampling Engine

Most of our plugins now share a new oversampling engine and a refreshed Settings panel:

• More oversampling options. Choose separate oversampling factors for realtime playback (up to 64x) and offline bounces (up to 256x), and pick 8, 16 or 32 Filter Taps to balance quality against CPU and latency.
• Your sessions won't change. A new Use Legacy Method toggle keeps the sound and latency of the previous oversampling engine. If you're upgrading, it's switched on by default, so projects in progress sound exactly as they did. Turn it off in Settings to try the new engine.
• Window Size. A new control in the Settings panel lets you snap the plugin window to 50%, 75%, 100%, 150% or a custom size.
• Refreshed Settings panel. Controls are grouped more clearly, and Avalon VT-747SP, Retro Sta-Level, Synth Warmer and True Dynamics now show their realtime latency in samples. In True 252, True Dynamics and True Iron, panels now close when you click outside them.

Avalon AD2055 and Avalon AD2077 get the refreshed Settings panel with the Window Size selector and the Use Legacy Method toggle.

True Iron 1.5.0: Groups

True Iron gets this round's biggest new feature. You can now assign any instance of True Iron to one of eight Groups with a new Group selector on the main UI. Each group has a shared On (bypass) switch and Output gain, controlled from the new Processing Options panel in the top bar. Flip an entire chain of True Iron instances in or out of your mix, or trim its combined output, with a single control.

True Iron's older Legacy Method and Linear Phase options have been replaced by the new oversampling engine. The DC Filter is still available in the Settings panel.

KClip Zero

KClip Zero gets a maintenance update, with a framework and SDK refresh in line with our other plugins. There are no user-facing changes.
