For Varian systems you can use Pbox to create the shaped pulse. This can be done in a variety of ways,form using cursors on the screen, to macros, to integrating in the sequence, to using a shell to create the shape. Pbox uses basic mathematical equations but they integrated in the compiled program. You can specify a set of fourier coefficients and Pbox will produce the shape. So if you can characterize your new shape by a set of fourier coefficients you can do it with Pbox.

Doesn't Bruker's Topspin 2.1 pl4 have an option for this in the shapetool?
