A few minutes after downloading Nodal last night, I realized that the only thing I'd be doing for the next week or so was connecting dots on a grid and clicking "play" to see what the drawing sounds like.
I haven't spent enough time with it to offer any tips, tricks or what have you, but as a general blanket recommendation, head over to their site and download the program (it's free). Be sure to grab their PDF tutorial, too-- you'll be up and running in a flash!
That said, Nodal is old news to some people. Has anyone reading this gotten comfortable with the software? Anything the rest of us should try that isn't covered in the manual? Please leave reviews/hints of any length in the comments. Thanks!
