Perhaps you should try some spelling variations:
"single channels" » "single channel", "side channels", "using 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 ("single chain")))).
• Removing quotes may allow a broader search: (((( synfire chain ) or ( singie chain ))) or ((( single channels ) or ( single chain )))).
• Adding a wildcard symbol may retrieve word variants: (((("synfire chain") or ("singie chain"))) or ((("single channels") or ("single chain"))))*.
