Nope, that would be hard ;) I was thinking of having a second, hard

I suspect this
dip is some kind of reflection from the limit, but I can't
tell without trying one.
you mean you intend to change valve to have adjustable
slope where it compresses? sounds good, if that is what
you mean. i did some testing with a simple
in -> valve -> invert -> valve -> convolver -> out
setup and it's beginning to sound like fairly good
distortion when the input signal is strong enough.
aliasing is very, very faint, with both valves set
for maximum saturation (and "character" = 1.). could
use some more saturation/clipping though.
Yes. Its not really meant to be distortion at that level, more of a
saturation thing. I usually put something hard in the middle (near the
inverter, a cliper or sinus wavewrapper, something like that. Probably
wont make a good guitar sound though.
two things: 'in' should probably be
HP-filtered, because
the low frequencies become too dominant. and the valve
Yes. Aparently they do this in the hardware too.
clipping is too strong at low input levels. it seems
to
adapt the clipping level to the input level. i think that
It doesn't. there are no time domain effects, and it doesn't adapt to
amplitude - just a static trasfer function. It could be an interrelation
with the two valves, but I dont think so...
it should rather have a certain threshold beyond
which
saturation becomes more noticeable. 'weak' input sines
are flattened almost completely, at very low amplitudes,
rendering a sound resembling that of a torn speaker.
Try turning down some of the parameters. You wont get good, hard
distortion out of the valves, more of a natural warmth.
