Magic Music Visuals

Hi there
I am a newbie so please bear with me if this is a stupid question or it has already been answered somewhere (I did try and browse in the forum with no success...)
I am merely trying to have some text fade-in one line at a time. I am using Text and Transparency modules (with ramp and invert) but the text keeps disappearing ands re-appearing because the ramp loops by construction.
So my 2 questions are:
1 - how can I have the text fade in and stay visible once transparency is equal to 0 (e.g. by a ramp) ?
2 - how can I delay each Text module activity (one for each text line) so that they appear one after the other (line 1, then line 2, then line 3, ...) ?
Thanks a lot !

Thank you for the answer. But it unfortunately does not work for me because I use a sound file to trigger the animations. I ended up using the Internals/Playback time and theColorHSB brightness (to avoid inverted limits):
But your answer helped me understand the principles behind Magic... So thanks again.
