Never mind-- figured it out.

In ‘C:\Program Files (x86)\Sonic Pi\app\server\ruby\lib\sonicpi\scsynthexternal.rb’, I added the ‘-H’ switch to the ‘boot\_and\_wait’ statement in the ‘boot\_server\_windows’ function, passing it the name of my soundcard (in my case, ‘Focusrite USB ASIO’).

Now I’m getting virtually no latency when using audio in!
