SPL TwinTube
SPL TwinTube is a VST/AU/AAX audio plugin that models SPL's analog TwinTube hardware processor. It combines two independent stages of tube saturation and harmonic enhancement, allowing users to add warm tube character, presence, and richness to individual tracks or buses. The plugin is part of the Plugin Alliance ecosystem and is commonly used by producers, engineers and mixing professionals working in digital audio workstations like Logic Pro, Cubase, Pro Tools and Ableton Live.

1 suggestionSPL TwinTube has shipped native Apple Silicon builds since version 1.17 (released March 2022), adding support for VST3, VST2 and AU formats natively, with AAX support added in version 1.18.0 (August 2023). The latest version 1.19.2 (March 2026) is fully native. To update, use the Plugin Alliance Installation Manager — the vendor's official plugin installer and update utility. Launch Plugin Alliance Installation Manager, sign in with your account, navigate to SPL TwinTube, and install or update to the latest version. This will automatically pull the native Apple Silicon build for whichever format your DAW uses (VST3, VST2, AU, or AAX). Do not try to update via a generic download page; the Installation Manager is the correct channel for all Plugin Alliance plugins.
