how do i make a delay that will blow up?

[travis]

you know, when the delays start getting louder than the source and it runs away..
i don't think I can do it with just one of the delay UGens?

b = Buffer.alloc(s,44100,10);
{ BufCombC.ar(b.bufnum, Decay.ar(Dust.ar(1,0.5), 0.2, WhiteNoise.ar), 0.1, 9) }.play;

You need a feedback loop so you can control the amplitude of the delayed signal fed back in. Look at LocalIn/LocalOut. Pseudocode, it would be:

signal = (source) + LocalIn.ar(numChannels);
LocalOut.ar(DelayN.ar(blah blah blah) * 1.1);
Out.ar(0, signal);

thanks. i'm rusty.

Everyone, post your favorite exploding synths!

to emulate the echoplex type of tape delay, it might be nice to add a distortion that accumulates as feedback does, and maybe experiment with pass filters

Hi aj,

Yeah, I've unsuccesfully tried to build a Space Echo a few times. Would need high & low pass filters, controllable "wobble" & "lag" and some kind of "tape" distortion.

Think I'll have to try again using hjh's technique...
