Hey there!

I wonder if it's possible to build a virtual guitar amp in sonic birth.
The tube overdrive is nice but sounds a little... well... digital...

Any ideas how to realize an amp simulation?

I thought about different distortion values for different frequencies but it sounds like cheap fuzz pedals.

Unfortunately I don't have the slightest idea how to model an amplifier in sonic birth.
Perhaps I could get some results using some mathematical functions in the equation modul.

So if someone's got any ideas I would be happy to hear about them.

Thanks in advance.

Okay... I found some information via google.

http://www.bteaudio.com/articles/TSS/TSS.html

http://music.columbia.edu/pipermail/mus ... 66483.html

To do a soft clipping via a tanh function and a hard clipping is done with ease...

But it sounds awful. It's not even close to a guitar stomp box.

So if anyone has done a guitar distortion before PLEASE HELP!!!

EDIT:

Found a complete mathematical model for a tube guitar amp here
http://www.simulanalog.org/tubestage.pdf

But... Well... I'm no genius...

Perhaps can someone translate this in SonicBirth language...

That paper sure is interesting. I'll work on it a bit and see if I can make sense of implementing that in SB. If you come across any other theoretical models, post links to those as well.

OK, I looked at it for a while. That work leaves on tube simulation leaves out too many details in the presentation of its final equations to be useful. Any other resources?

I've been doing some reading and finding other resources. I think I can get something pretty good together for SB by the weekend.

WOW... sounds great. I tried many things and spent nearly 3 days without a even nearly useful result.

I know how things work in theory. But getting that to work in SB isn't that simple for me.

Thank you very much!!!

Anyone ever tried to build an amp simulation???
