We've been using Simian 1.6 for several years. I need to switch operations to a new computer, but don't remember & can't find how to mute the incoming feed to the PC during playback of a file.
After you install the application, the Simian Pro 2.3 Manual.pdf is placed on your desktop. I have checked the Simian provides you with the features to AutoMute various mixers and lines. Open that file and then simply press CTRL + F. Type Mute to locate the correct procedure on how to mute lines.
