Too bad there's no PERCOLATE for pd any more... Strange cus it is still around for Max, wonder if anybody could ever report it?
You could always use something like C-Sound with the pd external, or use OSC to control something like SuperCollider...
What style is it that your compositions are in?

I forgot to mention that absolute control of pitch is essential. I need to tell it what frequency the fundamental sounding pitch is. Naturally I want complicated waveforms, but FM and (I've just discovered) hardsyncing don't work...

Hi. My Pure Data Just Intonation sequencing program is up and running, and I'm in the process of making music with it for a dance/music ensemble at my school. The problem is everyone says it sounds like Mario. I tried making a granulator, and it sounded good but used so much CPU I couldn't incorporate it into my sequencer. What I do have is 16 harmonics, filtered noise, a bp/lp/hp selector with cutoff and Q control, and adsr sliders. I have 8 copies of this, each of which only runs when it is changed, and writes its results to a graph, which the sequencer reads. Thus it is also possible to draw the waveform with the mouse, which I've found can make it a little less predictable. But too much of that makes it inharmonic, and even so it still sounds very 80's. I'd like the freedom to work in more sophisticated synthesis. What can I do?
there are various other ways to shape synthetic sounds, particularly as a part in a subtractive synth: have a look at frequency modulation, amplitude/ring modulation, oscillator hardsyncing (resetting the phase of an oscillator by another oscillator), or pulsewidth modulation. you can create very interesting sounds if you gently combine these methods, for example feeding a hardsynced oscillator output as a frequency modulator into it's own sync source... something that works good on more complex signals than sinewaves is having a signal delayed by a (maybe amplified, dc'd and shaped) form of itself (having the signal as a source for the delay length of a vd~). be sure to check if lfos and (adsr-)envelopes applied in any part of your construction (modulation depths, frequency microtunings, filter cutoffs, pulsewidths, etc.) can do any good. with such techniques, your synths won't sound like mario, but more like luigi or princess toadstool. another approach might be simple physical modeling: you can create a plucked string which sounds crappy in the bass region but fairly harp-ish in the upper octaves by sending a short, single triangle- (or whatever-) shaped impulse into a feedback loop the length of the note frequency^-1. with a slight lowpass applied on each iteration the signal will warmly fade out. just ask if you have any questions about implementing these techniques.
