Subject:KX is more than a low latency soundcard driver!

Hey all who are playing the B4 with the kx sound card driver...

I've seen numerous posts about speakeasy preamps and such, but if
you dig a little more into the docs that come with kX you'll realize
that the KX driver's default DSP routing can be overridden through
drag and drop "programming".

There are so many plug-in effects that come packaged with this
driver that it would make most of you drool.

I decided to dump the default kX DSP setup and see if I could get a
sweet overdriven tube sound through my 120 watt MOSFET solid-state
home built Leslie 145 (http://www.vintagemusicprojects.com).

It takes a little reading to get the gist of this, but I now have a
DSP setup that is clean tubes for the most part until you lean into
the pedal at the upper end of its travel range then you get that
gritty, grinding Hammond/Leslie distortion that this combo is noted
for.

Here's my setup:

- FXbus 0 and 1 out wired to "gainHQ" with gains set to 15
- gainHQ out wired in parallel to "peak" (a meter), two mono
overdrives, and "in1" of "stereoMix". Overdrives are set to "gain1"
of 100% and "gain2" of 75% each. The peak on output of gainHQ is
monitored so you can adjust gainHQ to -6 to +6 dbVU which will get
the overdrives starting to distort.
- output of each mono overdrive is driven into Lin and Rin
of "TubeSound" whose amount is set to 90%.
- output of TubeSound is wired to Lin and Rin of "APS Compressor"
which is set to: attackTime=0, releaseTime=200, outputGain=15,
Threshold=-20db, Ratio=3, PreDelay=0.0
- output of APSCompressor is wired to "in2" of StereoMix. StereoMix
is set to In1Level of 77%, and In2Level of 48% (this sets how much
of the overdriven tube sound is mixed with the clean sound - adjust
to taste)
- output of StereoMix is wired to PhatEQ (a parametric eq) set to:
Frequency=around 7Khz, Width=2.04, inGain=-5.47, Type=LP (low pass)
- output of PhatEQ is wired to WaveL and WaveR of "xrouting"
- output "stereoL" and "stereoR" of xrouting is wired in parallel
to "epilog" "AnalogFrontL", "AnalogFrontR", and another Peak meter.

And...it didn't cost me anything, but if I had to put this together
in hardware you can see from the effects used it would have cost a
small fortune. And the best part? If I want to add more effects to
fine tune the sound or create a different sound I have much more at
my disposal.

The capabilities of the kX driver warrant more investigation by all
of you B4/kX owners, most definitely!
