Whoops! Try attached... it's not a standalone patch, and takes a creation arg ($1) as the table name.

Hi, this patch looks interesting, but it is broken for me: I get a whole lot of "error: : no such object" as soon as I start it. Moving the sliders also gives me this error. I'm using PD-extended on Wincrap XP (at work - programming PD when I'm supposed to be typing letters and adding up receipts).

This GOP patch takes as $1 the name of the table you want to use. Do a tabosc4~ and it sounds ok.
I think getting the waveformed tuned by hand and not simply by using mathematically exact proportions gets you closer to the sound you want, gives you a little randomness on the proportions. For a nice square wave for instance add just a tiny bit of the lower even-numbered partials for a more realistic sound. A problem you're going to run into with waveforms with too high partials is aliasing, though this diminishes the quality with lower fundamental frequencies... tradeoffs of the digital domain...

You want band limited functions which Pd doesn't have by default. Someone may have externals that do band limited saw and pulse waves available.

Hello everyone,
I'm working on a set of abstractions that will allow users to easily sequence rhythmic-pattern style music; basically, to make it easy to create IDM/electro/minimal-techno style stuff. Anyway, there's one
major
weakness to the whole project: PD oscillators don't sound good! Also,
the
filters I've tried don't sound very analog at all.
So, my question is:
- Does anyone have any good, "analog-sounding" oscillators already
created? I guess I only need saw, PWM square, and triangle, but they
need
to sound GOOD (like Reaktor, basically). I see how to do simple
versions
from the example patches, but I don't know enough DSP to get rid of
the
digital sound. For a great example of the kind of sound I want, check
out:
Asynth vst from antti at smartelectronix. http://antti.smartelectronix.com/
What would be the most analog sounding filter to use?
Is wavetable synthesis a reasonable option? How do I create a
custom
table to use for such synthesis? For example, if I synthesize a wave
of
one period in another program, how long should it be? I know this
should
be easy, but my brain is broken on this question. My gut instinct is
that
a wavetable would only sound good near original frequency or you just
get
the typical digital artifacts from pitch-shifting a sample... is that correct? I'm guessing what I'm really talking about is ROMpler style multi-sampling, and selecting the wave closest to input frequency.
Don't
know if anyone built this already.
Btw, I can solve the problem for myself by loading in the VST~
external,
but I want what I build to be cross-platform so that it is most useful
to
interested people in the community.
