Calypso comes with five true legato sounds, the vowels (considering mm as a vowel in this context), plus an array of twelve consonants to add to the beginning of your phrases.

There is also a true legato function (the green F keyswitch). Hold this down whilst playing, and whatever you play will be legato, plus you won't have to worry about missing an interval here and there because you didn't hold down the notes whilst playing, saving a lot of editing time! Ensure to release the legato aid key BEFORE playing the last note of the phrase, otherwise your notes will stick!

The consonants included, shine most when used as little additions to the beginnings of phrases. (See the demos for examples). They are not designed to be held down for too long and looped, otherwise you will lose the realism. If you choose to start a phrase with a long note (say three and a half seconds or more), then choose one of the five vowels. Stylistically and realistically this is by far the better option.

Consonants are added at the beginning of every legato phrase. So if you play a phrase "D, F, A" all legato, with "sah" selected, your phrase will sound like thig: "saaaaaaah", not "sah sah sah". The consonants do not insert themselves between legato intervals to ensure the sound is as natural as real as possible. Whilst specializing very strongly in emotional, soaring operatic vocal lines; Calypso is also extremely capable with little runs and turns, as you can hear in the Rusalka demo, making it an extremely versatile instrument.
