Tube Channel 1.2.0 — Eco mode

Tube Channel 1.2.0

Tube Channel 1.2.0 adds the reduced Eco engine as the default for new instances. The System page orders the engine buttons Eco · Circuit · HQ. Circuit is the renamed Default mode. The original circuit implementation remains available.

This release now includes both the existing macOS installer and a new Windows installer.

Downloads

Platform	Installer	Formats
Windows 10/11 (64-bit)	TubeChannel-1.2.0-win.exe	VST3, CLAP, LV2, Standalone
macOS (Apple silicon & Intel)	TubeChannel-1.2.0.pkg	VST3, Audio Unit, CLAP, LV2, Standalone

Both installers include the user guide, screenshots, project license, and applicable third-party license texts.

Windows installer notes

• Double-click the downloaded .exe and follow the steps. You can choose which formats to install.
• The installer is not yet code-signed, so Windows may show a blue "Windows protected your PC" dialog. Click More info → Run anyway. The file is safe.

What changed in 1.2.0

• Eco engine: measured filters and asymmetric nonlinear maps without runtime circuit solves.
• Independent oversampling: 2x, 4x, and 8x (the Derp symbol) work with any engine at any sample rate. Click the selected factor to return to 1x.
• Performance: local measured workload reached 26–35x at 48 kHz and 14–19x at 96 kHz versus v1.1.4 Default.
• PSU simulation remains off for new instances.

Important notes

• Eco is a measured approximation. Heavy-drive harmonics, aliasing, tube memory, supply dynamics, and component variation can differ from Circuit/HQ.
• Older sessions retain their original engine and automation.
• No AAX binary is included in either installer.

Licenses

• Source code is MIT licensed.
• Provided binaries are freeware.
• Builds use JUCE 9.0.3 under a commercial JUCE Developer license.
• Full third-party licenses are bundled in each installer.
