Thanks.

How would one make a delay with negative feedback?
Does anyone have an example?

Hi forum.

I have a maybe broad question, about certain techniques in creating drones. Drones of specific quality, the kind you can hear in Joe Colley's work, for example.

I'm not sure if I'm allowed to post some short clips from the tracks here, so here are some titles (with links):

Joe Colley & Jason Lescalleet - Prayer*
(http://sonmarchive.es/index.php?option=com_muscol&view=album&id=2644&lang=en)

Joe Colley - Headache (Diagnostic Testpulse For Blown PA)* - at ~8 mins
(http://sonmarchive.es/index.php?option=com_muscol&view=album&id=1012&lang=en)

crawl unit - Untitled (Drone 2)*
(http://sonmarchive.es/index.php?option=com_muscol&view=album&id=1006&lang=en)

So, in a lot of Colley's tracks...

David Wells - 2.1*
(http://sonmarchive.es/index.php?option=com_muscol&view=album&id=500&lang=en)

Tatar - 072304

etc...

*Sorry I couldn't find the tracks anywhere else except on this site. You have to register in order to listen to them.

Anyway, quite a few people have this sound in their music...

It's that dense textured drone, but also very clean sounding (as opposed to the noisy ones I usually get from using delay or reverb) and seamless (you can barely hear any sort of repetitions from the delay, and even when you do it's very 'soft').

You can hear in the examples, some have more dynamic sound while some are more static. I think I can notice the characteristics of feedback at work in the dynamic sounding ones, and the typical delay (set at short time) in the static sounding ones.

OK, so I'm guessing it's all at least 80% based on effects. Delay, reverb, feedback... but how?

I know that some people have achieved this sound by using pd, working on sample-based loops or instruments, but I haven't managed to do it.

I know it's not a very specific question, but if you can shed any light on this it would be awesome.

Thanks!

Yes, I've noticed the filtering.

@newlin
I've been, more or less, approaching it like that so far.

Does you know some good patches for this sort of thing?
