Mixtube is a VST effect designed to emulate the input stage of a tube-driven mixing console, bringing warmth and thickness to any audio track. By simulating the characteristics of classic analog hardware, it enhances the sonic texture of vocals, bass, drums, and other instruments, helping them blend smoothly into the overall mix.

This plug-in introduces harmonics and subtle compression based on the input signal and the drive control, which adjusts the level of saturation. It smooths attack transients and can add both even and odd harmonics, contributing to a rich and dynamic sound. Its simple interface allows users to achieve a tube-like effect with minimal effort, making it ideal for adding driven tones to direct-recorded electric bass or fattening drum tracks.

Mixtube features two selectable circuit emulations and continuous tube gain adjustment, paired with analog-style metering for visual feedback. Optimized for low CPU usage, it provides a vintage-inspired sound without taxing system resources, making it suitable for use across multiple tracks in a mix.
