Ulesto and Arjan, thank you for the info. Honestly, at this point, I don’t think I would ever find myself using this pencil tool. I mean, it’s possible, now that I am clear on its operation and purpose, but I truly doubt it. Using Crossfade in the past there have been occasional clicks, true, but I have always been able to figure a way around it when it happens - and not using the edit window pencil feature. (Of course, the key to getting the Crossfade to perform without clicks is to expand a wave large enough to see the centerline of the wave and cut it there before joining sections, and most folks using Cubase know this.) On the occasion that somebody brings me a really bad recording with clicks in it that needs to be cleaned up, WaveLab is much easier to use for this purpose, as you point out, Arjan.
Well, thank you all for getting me on the right page. I realize it makes me look naive and Cubase illiterate to post my original question but I really could not understand the process or reasons to use the pencil tool. The scale of the process just did not make sense to me. And now that I do understand it I also believe that I don’t think I need it much in my process. Ha! But I’m sure some here use it all the time, no offense intended.
