[LAD] simulating analog audio devices part II

[Robin Gareus]

hello again.

Sorry for the late reply, but I could not spare any time to work on it
the previous week(s)..

I'm sorry; can't help you on this one. Should you find some, I'm
interested, too.

Try searching the internet for <device-name> and add some <spice model
syntax> (eg. Is= Rs= ... #more `locate .model`) - that helped me to find
a specific Zener-Diode model, but tubes are more tricky; I suppose
most models of them are copyrighted somehow.

I barely scratched the surface of oregano. Model&library preferences are
not accessible in the 0.60.0 version - I got lucky placing a .model file
named after the device in /usr/share/oregano/models/ before I switched
to editing netslists with a text-editor after an initially generating
them with oregano.

I've only just installed qucs and like it. Working on schematic entry
it's much faster! (oreagno's wiring still sucks)

It'd be great to run a full simulation of a setup.

more later,
