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