I'm not familar with the kaoss pad - but for the EFX Flanger effect you can
control the "send" amount to the effect using the alSource3i(sourceID,
AL_AUXILIARY_SEND_FILTER, auxeffectslotID, iSendNum, filterID) where
filterID is the name of a Filter object containing Gain and Gain HF. If
you only want to hear the "wet" signal only then you can attach a Filter to
the "dry" path using alSourcei(sourceID, AL_DIRECT_FILTER, filterID) where
filterID has a Gain parameter set to 0.0.
If you want to just play with the effect then you can use the EFX10Show
application included in the SDK. Load the application and do the
Hit "Proceed" to use 2 sends
Select the "SB X-Fi Audio" device
Press "Create Slot"
Select Flanger and press "Load"
Press "Ctrl+A" and find a suitable wave file to load
On the Source Properties Dialogue box press "Create" in the 'Send 0' box
and use 'Gain' and 'Gain HF' to control the sends to the effect
Also on the Source Properties dialogue box, in the 'Direct' box use Gain
(and GainHF) to adjust the dry path
On the main dialogue adjust the Flanger properties to control the effect.

.com [Openal] EFX - Flanger Info
I recently got an XFI card so I could try out some of the efx extensions.
As I went through trying a few everything worked as intended; however, I
would like to know to make the settings for a dsp flanger effect for like
djing, and translating that to the settings I need for the EFX flanger. For
example, the kaoss pad has some nice effects, that you can drag your finger
and give a ranger of low to high http://www.youtube.com/watch?v=owkeBOcC-AQ
(you'll see what I mean).
I can hear the flanger taking effect on my song, but its not really 'loud'
enough; does the kaoss pad kinda throw in a low pass filter with the
flanger effect to give the total effect? Would this be what I need to do
for mine situation?
