; Explosions
; Noise filtered by fofilter.
; After p8 s attack time, linear decay to 0.
; The filter frequency varies linearly between p4 and p5.
; The fofilter impulse rise and decay times are given by p6 and p7.
; p6 low: smoother sound, p6 high: more rumbling sound
; p7 low: low deep sound, p7 high: tending towards white noise
; p8: attack time (s)
; p9: maximum amplitude
