Glissando and Portamento

[Hanno <shaftoe nurfuerspam de>]

Hi folks!

There is one thing thats catching my eye and does not belong into the 
instruments Im experimenting with. Is there a handling for portamento (more 
or less fast sliding from one tone to another, thats a midi-effect and has 
some more parameters like how fast the slide has to be done and so on) and 
glissando, which is almost the same, but on halvtone-steps like you'll go on 
a keyboard?

best regards Hanno
