A Pedal that sounds like the THX sound test?

Iz Jokes.

But seriously I want one. I wont rest untill peoples heads are bursting.

Any pedal that can do +/- 2 Octaves could do it... but if it was triggered :cool:

It was a computer program in C, which is kind of fun. Apparently you'll be more likely to reproduce it by doing a volume swell? http://en.wikipedia.org/wiki/Deep_Note

Hypothetically...Use an ebow (or a real bow). Pitch shift down one octave, and up (almost) one octave at the same time. Use a thick, slow, warbly chorus at first, and reduce it's depth as you pitch shift.

That's how I'd do it, anyway. I haven't actually tried it though.

I am thinking the PS-6 on the S bend where it goes octave up and down together plus the pog to add some octaves
might use a volume pedal and some verb and crisp dirt (distortion type)

30 different voices that all start in a close range, and then spread out over 3 octaves. That's gonna be rough to do. I would think you'd need at least 3 different voices for it to sound convincing at all. Can the Pitchfactor do that? Most pedals can only do two voices.

30 voices, but only 1 pitch diverting into 2. It's 10 voices up, and 20 voices down; not quite in unison. A chorus pedal would add the illusion of more voices, but you'd need either a fairly powerful softsynth, or an orchestra to get it exact.

A good sampling pedal.

I am close

Whammy set to octave down
Original Pog Maxed pretty Hard
Boss RV-5 on modulate (instead of chorus)
boost DLA
and then the PS-6 on the S bend setting set to the slowest setting
You have the depress the PS6 First Play a hard chord a D seems Good in dropped D tuning
Then Release the PS6 and let it bend back to the original pitch

it's really close but I think I need to add something somewhere to make it happen

My friend has a keyboard that can do this. You can set synth voices to have insanely slow glissando, so if you play a note, then the octave above and hold both it takes take 30s or so to get up an octave at the slowest, and you hear both notes the whole time. Amazing.

I don't think that's correct. From the description on Wikipedia, it sounds like there are more than just 2 different pitches. And the final finishing chord sounds like it has more than 2 pitches in it. It sounds like several octaves and some harmonics.

"The THX logo theme consists of 30 voices over seven measures, starting in a narrow range, 200 to 400 Hz, and slowly diverting to preselected pitches encompassing three octaves. The 30 voices begin at pitches between 200 Hz and 400 Hz and arrive at pre-selected pitches spanning three octaves by the fourth measure. The highest pitch is slightly detuned while there are double the number of voices of the lowest two pitches."
