Perhaps you should try some spelling variations:
"synfire chain" » "entire chain", "synfue chains"
"synfire chains" » "entire chains", "synfue chainss"
"singie chain" » "single chain", "single chains", "ising chain"
"single chip" » "single chain"
"side chain" » "side channel"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("synfire chain") OR ("synfire chains"))) OR ((((("singie chain") OR ("single chip"))) OR ("side chain")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"synfire chain\") or (\"synfire chains\"))) or (((((\"singie chain\") OR (\"single chip\"))) or (\"side chain\"))))".
• Removing quotes may allow a broader search: (((( synfire chain ) or ( synfire chains ))) or ((((( singie chain ) OR ( single chip ))) or ( side chain )))).
• Adding a wildcard symbol may retrieve word variants: (((("synfire chain") or ("synfire chains"))) or ((((("singie chain") OR ("single chip"))) or ("side chain"))))*.
