[Pd] Other synthesis methods

[cyborgk at nocturnalnoize.com]

If Chuck is on Linux, hopefully that will be helpful for him!!! But it's
not cross-platform (I'm still on Windoze).

For me in the present - looks like I have to stick with Max/Jitter to run
Percolate. Question: If I did get Linux going, and I'm using
Demudi/Ubuntu, I have to compile Percolate myself right, cus it's a
different distribution? How hard would that be? Having those sounds would
make PD definitely more attractive for synthesis, I actually lately was
using it with GEM for visuals. and not for audio, because of some of the
limitations involved in having only low-level building blocks. I'd kill
for some externals/abstractions that have anti-aliased, analog sounding
square and sawtooth waves, for instance... Anyway, I still like PD enough
I'll probably run other things like Reaktor and Max/Jitter using OSC. Cus
PD is elegant. And with GriPD I think it will be nice for interface
design.

PS. Yes, I do plan to fix my laptop to dual-boot to both Windoze (sorry
some software is too good to give up, unless I get a Mac), but given the
complexity of getting Linux running well with all software I need, that's
probably not going to happen for 6 months. I will say, the Demudi-Live
boots up okay, but I'm not sure how to set up things to get it running
beyond that (partition/install/configure for audio). Most instructions out
there make assumptions that just don't make sense to a non-Linux user
(they skip steps, assume knowledge you don't have, don't explain things in
detail). Somebody write some better help documents for this stuff!!!
