is a digital approximation of the famous Moog Ladder filter. \r\nIt is based on the work of Antti Houvilainen. \r\nCode fragments found at:  http://musicdsp.org/showArchiveComment.php?ArchiveID=196\r\n\r\nIt has a double steep 24dB/Okt roll-off compared to the \"Filter effect\"\r\nThe resonance can be cranked up to self resonance, which produce a prominent sweeping effect.  \r\n\r\nIMHO this is a nice addition to MIxxx and a good counterpart to the subtle \"Filter effect\" pull request, which is included in this PR as well. \r\n\r\nBoth are designed to be an EQ replacement if desired.\r\n\r\n","created_at":"2014-10-05T18:49:00Z","updated_at":"2014-10-08T22:06:28Z","closed_at":null,"merged_at":null,"merge_commit_sha":"09efbc38ebd0427258213a22bc0b87815811dbf5","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/mixxxdj/mixxx/pulls/354/commits","review_comments_url":"https://api.github.com/repos/mixxxdj/mixxx/pulls/354/comments","review_comment_url":"https://api.github.com/repos/mixxxdj/mixxx/pulls/comments/{number}","comments_url":"https://api.github.com/repos/mixxxdj/mixxx/issues/354/comments","statuses_url":"https://api.github.com/repos/mixxxdj/mixxx/statuses/e327f2474e5c731f75e70bca1e1ad613f0d2763d","head":{"label":"daschuer:moog_ladder_filter","ref":"moog_ladder_filter","sha":"e327f2474e5c731f75e70bca1e1ad613f0d2763d","user":{"login":"daschuer","id":1777442,"avatar_url":"https://avatars.githubusercontent.com/u/1777442?v=2","gravatar_id":"","url":"https://api.github.com/users/daschuer","html_url":"https://github.com/daschuer","followers_url":"https://api.github.com/users/daschuer/followers","following_url":"https://api.github.com/users/daschuer/following{/other_user}","gists_url":"https://api.github.com/users/daschuer/gists{/gist_id}","starred_url":"https://api.github.com/users/daschuer/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/daschuer/subscriptions","organizations_url":"https://api.github.com/users/daschuer/orgs","repos_url":"https://api.github.com/users/daschuer/repos","events_url":"https://api.github.com/users/daschuer/events{/privacy}","received_events_url":"https://api.github.com/users/daschuer/received_events","type":"User","site_admin":false},"repo":{"id":10669071,"name":"mixxx","full_name":"daschuer/mixxx","owner":{"login":"daschuer","id":1777442,"avatar_url":"https://avatars.githubusercontent.com/u/1777442?v=2","gravatar_id":"","url":"https://api.github.com/users/daschuer","html_url":"https://github.com/daschuer","followers_url":"https://api.github.com/users/daschuer/followers","following_url":"https://api.github.com/users/daschuer/following{/other_user}","gists_url":"https://api.github.com/users/daschuer/gists{/gist_id}","starred_url":"https://api.github.com/users/daschuer/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/daschuer/subscriptions","organizations_url":"https://api.github.com/users/daschuer/orgs","repos_url":"https://api.github.com/users/daschuer/repos","events_url":"https://api.github.com/users/daschuer/events{/privacy}","received_events_url":"https://api.github.com/users/daschuer/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/daschuer/mixxx","description":"Mixxx
