I found those, but are they really band-limited? I'm fairly sure I hear ugly digital artifacts in the saw. The square appears to be broken, unless I made a mistake cutting and pasting those 1500 lines of code into my text editor (kinda hard to tell).
It's 5 30 am here and I've not slept yet :-(
I can't believe there's STILL no readily available external/abstraction for such a common synthesis task, I just want a "nice sounding" example that will compare with the VST's which I will be hosting from within PD; right now "ASynth" sounds about 100x better than anything made in PD itself ...
Oh and I don't see any "J" example PD patches, my PD patches don't go that high.

hello david
i found examples for a bandlimited saw and bandlimited square by g. geiger in the archives. might this is what you are looking for.

Hello everyone,
I tried google and it was no help, and the server for the list archive seems to be down temporarily.
Anyway, I'm giving a free (as in free beer) workshop in Chicago in about 16 hours, on the basics of digital synthesis. I have decided to use Pure Data to give my presentation, and use mostly non-commercial software.
However, I'm still missing the following for demonstrating "proper" subtractive synthesis:
- Good, out of the box "analog-sounding" filters. I'm using [moog~]
right now, but I'm not all that satisfied with the sound compared to the filters in my favorite VST's ... 2. Band-limited square and sawtooth waveforms.
For teaching purposes PD is great, and ideal for my demonstrations. But as it is, I'm having to use VST's within PD in order to demonstrate a "nice sounding" synth. It would be nice to show that PD can do it without using stuff built in Steinberg's format. That would also let the Mac people replicate my work, if they are interested. Note, nobody in the workshop has ever tried Linux, except me, so Linux plugins are not helpful in this case.
I will post my patches after I give the workshop, though they are nothing fancy ... just basic: sequencer - oscillator - vca - filter. Good for demoing though, I'm starting with additive first, then subtractive.
