All musical instruments generate an attack (initial amplitude change from zero to full volume of any note. Can be near-instantaneous, as with a synthesizer or piano, or slow, as with a string "pad"-like part. "Slow strings" usually just means a slow attack. And a string attack is quite complex, not just a simple volume change.

The strings I use (Celtic Air 085) have a large change in pitch and amplitude for the first tenth of a second or so at slow tempos, this waver is usually caused by playing a sample at too slow a playback speed, strings are especially prone to this issue, it's just the way the rosin grabs the strings.

If I can adjust the attack time (with a gate...) from BiaB, I don't need to take the track to a DAW. And I thought I had seen something like this, but I could easily be hallucinating... :-)

It's all about the music.
