I've just done a quick and dirty test of this with quite interesting results.
For a short while I have two files on my website:

http://www.musically.me.uk/Attack_Test_0mS.mp3
and
http://www.musically.me.uk/Attack_Test_15mS.mp3

These were recorded using yoshimi and the default AddSynth sound simply
triggered with the virtual keyboard. Unfortunately, I don't have time to cross
check with subSynth at the moment :(

If you look at them with audacity and at a very stretched scale, you will see
that they all start with a negative going half-cycle and there is absolutely no
offset, and no significant distortion. Therefore the seeming pulse sound is a
purely psycho-accustic effect.

The 15ms attack ones are more interesting as they show a nice increasing
amplitude at low pitches (which sounds nice and smooth) but that rapidly
dissapears as you go up in pitch. This I would suggest is a bug in the
implementation - apparently true of both zyn and yoshi. 15mS attach should
*always* be 15mS.

I don't usually cross-post but I think this will be of significant interest on
the yoshimi list.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
