Re: [PD] dub chords in Pd
A huge part of the old dub sound is the saturation of the delay lines, usually with some filters to carve up the echo as you suggest, Felix. But one problem in Pd is that delay lines and filters tend to blow up instead of saturate like the old school gear. One of my biggest problem patches was a recirculating delay line with a high pass filter. Inevitably, it would die, killing the DSP chain with NaN output. Only way to get rid of it was to cut and paste the offending filter and delay line. I suppose someone could come up with some DSP wizardry to emulate that analog saturation. But I have been getting a strange kick out of all these how do I imitate threads... How do I imitate the sound of a very long tube? How can I waveshape the sound of an overdriven speaker? Where can I download a physical model of the sound of water? What kind of algorithms produce the sound of a Slinky going down stairs (alone or in pairs)? Is it really so difficult to use the real thing itself? (Of the above examples, the Slinky might be the most difficult thing to locate in one's studio...) *Must* everything be emulated in this imaginary, digital world? Ahem... I'll go have my coffee now.

Re: [PD] dub chords in Pd
To Roman's suggestion, this works well. For the sake of your speakers and DSP chain, I'd add a [clip~ -1 1] to the end of that to be safe, and place that combo both right before the [delwrite~ dub] and on the output stream. For the sake of maximum dub, use a [vd~] instead of a [delread~] and slowly apply modulation to the base index delay amount. Say, 500ms +/- 50 by modulating the base amount either with a periodic function or [lop~] filtered [noise~]. I've yet to try this, but in my head it seems dubby.

Re: [PD] dub chords in Pd
Hi, 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!
