On the first page of your catalog #974, you said you can synthesize the sound of a Galactic Explosion. I'd love to know how to do this.

Recently, Allen Fairfield of Wakefield, Mass, sent us a patch he devised. His letter and patch should answer your question.
"Your catalog mentioned being able to synthesize a galactic explosion. Well, after getting a nifty idea from the "Jetliner Take-Off" in the 1/76 issue of Polyphony, I figured out a pretty good explosion.
The bias controls for both filters should be adjusted for the best explosion. I used a function generator in the patch, but the ADSR would most likely give a better result. A reverb unit might be nice, too, but I don't have one (yet). Also, how about changing attack time to about 50% and adding reverb to get a thunder sound."
(Also, see the Patch section of this issue for more thunder patches.)
Bandpass Filter Q: 75% to 100%
-5 to +5 bias: -1 volt
0 to +5 bias: 4 volts
Inverter: 5 volt offset
AR: Expand off
Attack - minimum
Release - maximum
Variable output - 60%
Try setting envelope attack to maximum and release to minimum for humorous "backwards" explosion effect.
