firstly thanks to all for the comprehensive replies and insights. Gonna try
out some stuff and report back if I got something good.

@Derek: I understand your point, I've never been so found of natural /
hardware sound synthesis, but presently I find very interesting to
understand the digital process which could allow me to produce certain
sounds. Makes me better understand the whole thing, and apart from that, I
cannot afford to buy hardware to make dub chords and delays at the moment.
I'd love to, but got to spend money in other essential equipment.
I agree with you that this kind of imitation works only to some extent, but
it is extremely interesting to me to learn how you can combine different
synthesis techniques, so that I can apply them later in other context, maybe
less imitative.

Honestly this dub chords stuff is just a curiosity, as I listen a lot of dub
don't need to do anything special with it :)

@Roman: backup blues is so good! I'm listening to it since 30mins... thanks
for sharing. Really nice Pd sound.

@Pierre: thanks for that! I reckon it clearly explain the point of Derek. :P
