Perhaps you should try some spelling variations:
"single channels" » "single channel", "side channels", "using channels"
"single chains" » "single channel", "single domains", "single chip", "single channels"
"singie chain" » "side chain", "single chip", "ising chain"
"single chain" » "single 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: (((("synfue chains") OR ("synfire chains"))) OR ((("singie chain") OR ((((("single chains") OR ("single channels"))) OR ("single chain")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"synfue chains\") or (\"synfire chains\"))) or (((\"singie chain\") or (((((\"single chains\") OR (\"single channels\"))) or (\"single chain\"))))))".
• Removing quotes may allow a broader search: (((( synfue chains ) or ( synfire chains ))) or ((( singie chain ) or ((((( single chains ) OR ( single channels ))) or ( single chain )))))).
• Adding a wildcard symbol may retrieve word variants: (((("synfue chains") or ("synfire chains"))) or ((("singie chain") or ((((("single chains") OR ("single channels"))) or ("single chain"))))))*.
