hi listers am now starting to use Izotope's Vynal; their free LoFi "record" emulation plug-in. in Sonar , I'm using JSonar; with Reaper , ReaAccess. from the accessibility point of view , it's accessible with the tab and arrow keys. after inserting the plug , which opens its interface window , press F6 to get to the plug's interface. now , for the tab and arrow keys to work , one needs to click the mouse on a control; then it gains the keyboard focus , and the tab/arrow keys start working as advertised in the help documentation. real good news. cheers Roy.
