If you want the european sound it should be 50Hz on the oscil.

Hello Adam,

i am not sure this can help or not, i just added instr2 to demonstrate fuzz sound:



;-iadc2 -odac1


sr = 44100
ksmps = 1
nchnls = 2
0dbfs = 1

gamix init 0

instr 1
asig inch 1
gamix = gamix + asig
; awsh distort asig, 1, 5
; outs awsh, awsh
endin

instr 2
k2      linen   1, 0.01, p3-0.01, p3-0.01
a2      oscil   k2*p4, p5, 2
gamix = gamix + a2*0.2
endin

instr 99
; adist     distort1 gamix*200000, 1, 1, 0, 0
; a99 = adist*0.00002
adist      distort gamix, 0.2, 5
a99 = adist*0.5
outs a99,a99
gamix = 0
endin



f5 0 8192 7 -.8 934 -.79 934 -.77 934 -.64 1034 -.48 520 .47 2300 .48 1536 .48
i1 0 120

f2 0 8192 10 1
i2 0   5 1   300
i2 0.5 5 0.6 240
i2 1   5 0.4 200

i99 0 120

e





to get soft distortion, you should use
adist      distort gamix, 0.05, 5

to get full distortion,
adist      distort gamix, 1, 5

and you can also use
adist     distort1 gamix*200000, 1, 1, 0, 0
a99 = adist*0.00002
in stead of
adist      distort gamix, 0.2, 5
a99 = adist*0.5

Thanks! I like the sound of the distort1 solution better than using
the ftable. Now I just have to remember not to distort my drums. ;)

I'm also working on a few ideas for using Csound to effect my guitar
sound, I'd love to hear what you come up with if you're willing to
share!

Another thing to consider might be using the pconvolve opcode with
impulse responses. I haven't tried it yet, but I've heard there are
IRs for speaker cabinets out there.

Apparently convolution is not suitable to produce distortion effects, since
it works in the lineair domain, it does not add harmonics that are not in
the original signal.
It is great for reverbs, though.

See the following thread on convolution and distortion...
