So now I am using a 64-sample buffer, and I don't notice the delay anymore. However, I think that I'm getting the occasional click, so I'm going to up the buffer to 128 and see if that solves it. I'm working my way through the tutorial at: http://www.djcj.org/LAU/ardour/ and there are a few descriptions of the GUI and how to do things that don't seem to match the GUI that I have. For instance: - "Engage the /dynamic punch/ button in the transport controls" (I don't see this button) - "put the mouse into select mode, select the desired section" (in the tutorial there's a button that says "select", but not in my GUI) - "click on the /redirects/ button to the left of each /edit strip/ and then the /add/ button in the /dsp chain/ window which will popup" (this is for selecting FX for a track, which I really want to do!) Thanks in advance for any help in mapping the tutorial onto the current version of the GUI (or helping me find these features, if I'm just overlooking them!) cheers, David ------------------------------------------------------- This SF.net email is sponsored by: The SF.net Donation Program.
