 ## Rough edges
 
 ### Standalone I/O
-The I/O for the standalone doesn't inherit the stability of most plugin hosts (DAWs), so it's a bit sparser on features. The most common sharp edge is that **only input 1 is supported**. If you have a dual-input interface where the guitar goes in input 2 (e.g. Focusrite Solo), then you're going to need to either (A) use input 1 (and, perhaps, a DI box) or (B) use the plugin (VST3/AU) inside a plugin host.
+The I/O for the standalone doesn't inherit the stability of most plugin hosts (DAWs), so it's a bit sparser on features. For complex routing, the plugin (VST3/AU) inside a plugin host is still the most reliable option.
 
 ### Graphics backend
 If you're having trouble with NAM crashing before the GUI comes up, then you might have an unsupported graphics configuration. Usually, this is when you have a dedicated graphics card (like an nVIDIA GPU) and you're using the integrated (CPU) graphics on a Windows system. To fix this, Go to the control panel, pick NAM (or your DAW), and make sure that it uses your graphics card. (If you know more and can help fix this, please make an Issue and let me know more!)
