How to get swing feel from dotted notation?

[Colin Campbell]

I'm transcribing a piece originally written with a lot of syncopation, 
using half-values ties across the beat, as well as what I think must be 
intended as a "swing" feel, notated with dotted rhythms. No problem 
reproducing the visual elements, but I also need to produce practice 
tracks for an amateur chorale, and the output in MIDI is very jerky. 
I've read /ly/articulate.ly but didn't see anything understandably 
useful. I think I need to turn the rhythms, both syncopated and dotted, 
into more of a triplet effect, in order to get the smooth swing I need. 
I've set up two \score blocks, to separate \layout and \midi, and 
\included "articulate.ly", but clearly, I need further suggestions.

A typical couple of bars look like this:
*****************************
{
\time 4/4 \key e \major
  r2 r4 r8 b
  e8 b16 e~ e8 fs16 a~ a gs8. fs16 e
  d8 e16 cs~ cs2 r8 b
 }

Cheers,
Colin
