I am confused by the 'swell' effect - there is no effect called 'swell' which is what confuses me. For example, in the Pad/Choir Category is a Pf called 'Brass Motion Pad' - which implies Motion Sequence is in there somewhere, but I cannot make any difference to the 'swell' nature of the Pf no matter what I do. I simply want to stop the swell so that it just plays the sound at constant volume. How do I achieve that, please? Indeed, if it's not too technical, how is the swell effect produced in the first place? Thank you!
