The plugin suite containing Loopcloud Drum and Loopcloud Play is now integrated into the Loopcloud installer, meaning that you only need one installer to install the Loopcloud standalone application, the Loopcloud plugin, Loopcloud Drum and Loopcloud Play.
You can find this by going to https://www.loopcloud.com/cloud, signing in and then clicking the blue download button at the top of the page.
By default the Loopcloud, Loopcloud Play and Loopcloud Drum VST plugins may have installed to C:\Program Files\Steinberg\VSTPlugins if you're using a Windows computer or Library/Audio/Plug-ins/VST and Library/Audio/Plug-ins/VST3 if you're using a Mac. These plugins will either need to be moved to the folder that your DAW looks at for plugins, or your DAW's preferences changed to point the DAW to the default install directories.
Once you've either changed your DAW preferences or moved the VST files into the correct folder, re-scan your plugins and then proceed to add the plugins onto an instrument or MIDI track using the Plug-ins browser.
