I am using Windows 8.1 64 bit pro and Ableton live lite 9 and softube time and tone bundle (64 bit) . But Softube plugins are not visible in Ableton. Any solutions for this ..
(a) Launch Ableton Live and go to:
Windows: Options > Preferences Mac: Live > Preferences
(b) Select the File/Folder tab, and under Plug In sources, toggle Use VST Plug-In Custom (Win)/System Folders (Mac) off and on again.
(c) Hold down the [Alt/Option] key and click Rescan.
Are you sure you installed the plugins in the correct VST folder?
Is your Ableton Live Lite 32-bit or 64-bit? Please refer to the help article below to verify you installed your plugins correctly and they match your Ableton version (you need to install 64-bit plugins only if you use 64-bit version of Ableton).
32-bit plug-ins won't show up in the 64-bit version of Live and vice versa.
