There is a way to make it move, which makes NVDA's progress bar beep trigger, however this has been found to be temperamental across different builds of Reaper - possibly portable versus full installation, possibly 32-bit versus 64-bit. \r\n\r\nWould it be possible to make this slider easier to focus and have speech report the slider's position? \r\n\r\nthe implications of such a thing being made accessible, assuming it's even possible are wide-ranging but here are a few. \r\n\r\nIf you have a compressor or noise gate you particularly like that doesn't support side-chaining, using this method you can make it happen.\r\n\r\nIf you want an eq and a compressor effect to work together, which can be useful in some mixing situations, as described in Reaper's documentation, I forget whether it's the wiki or the manual, this is how to do it. \r\n\r\nIf you want the panning of one track to follow the panning of another, this is how to do it. \r\n\r\nThere are also a tremendous number of sound design implications such as the ability to create level modulated reverbs or filters etc. \r\n\r\nthanks and I hope this explains everything, \r\n\r\nJustin "},"comment":{"url":"https://api.github.com/repos/nvaccess/osara/issues/comments/187147846","html_url":"https://github.com/nvaccess/osara/issues/71#issuecomment-187147846","issue_url":"https://api.github.com/repos/nvaccess/osara/issues/71","id":187147846,"user":{"login":"jcsteh","id":4166475,"avatar_url":"https://avatars.githubusercontent.com/u/4166475?v=3","gravatar_id":"","url":"https://api.github.com/users/jcsteh","html_url":"https://github.com/jcsteh","followers_url":"https://api.github.com/users/jcsteh/followers","following_url":"https://api.github.com/users/jcsteh/following{/other_user}","gists_url":"https://api.github.com/users/jcsteh/gists{/gist_id}","starred_url":"https://api.github.com/users/jcsteh/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jcsteh/subscriptions","organizations_url":"https://api.github.com/users/jcsteh/orgs","repos_url":"https://api.github.com/users/jcsteh/repos","events_url":"https://api.github.com/users/jcsteh/events{/privacy}","received_events_url":"https://api.github.com/users/jcsteh/received_events","type":"User","site_admin":false},"created_at":"2016-02-22T12:12:19Z","updated_at":"2016-02-22T12:12:19Z","body":"Just tested on a portable and it works fine here. As I say, one of the \nother check boxes must be checked in order for the output gauge to move; \ne.g. Audio control signal (sidechain). You'll need to disable NVDA \nsimple review, tab to the baseline check box, move to containing object, \nmove to next object (which should be a window) and move focus to \nnavigator. The key point is that you have to focus the window containing \nthe slider, not the slider itself, because REAPER's accessibility \nimplementation is buggy.\n"}}
