OK, I have read all the tutorials including Lex's on setting up Cubase. I have been able to get a few rudimentary DSP setups working and sort of understand what's going on. The one thing I have not been able to get working correctly is using a VST plug-in effect via a VST host with KX. My biggest problem is, if I get the effect working, the dry sound is mixed in with the effect sound. I only want the effect sound.

My goal is to have the Mic input get processed by the VST effect and pass through to an online game with ONLY the result of the effect present. I am using the ProFX plug-ins since they seem the simplest.

I am using Cantabile Lite (as the host) with a VST plug-in. I can hear the results of the effect on the speaker outputs PLUS the unprocessed sound. Same thing for the recorded ASIO output. It seems though, that no combination of Record Monitor, Main, etc. in the MX6 mixer will kill the sound of the unprocessed input from the Mic without either killing the sound entirely or creating a feedback loop or creating a mixed signal. Either I'm missing something or the driver isn't capable of doing this?

Here is my DSP setup....

My second problem is that the open source VSTHost doesn't see the KX driver correctly. Anyone know why?

You need to show how ADC and MX6 are configured...

Make sure the Mic input on MX6 is 'R'ec and 'E'nabled (lit)- but 'M'ain is off (un-lit).
Make sure ASIO 4/5 are NOT 'R'ec enabled in MX6 - (could cause a feedback loop).

Thats not an ADC - 10K2 cards should have a UDA output on it...no?

Russ

Yup (unless it is an older version of kX/ProFx), I did not notice that it was a 10k2 card.

@PurpleMoose
What version of kX are you using?
How is the MIC connected (rear of the card or drive bay)?

Maddogg6

Also - keep in mind - I can use a SRC for AC97 (-2) aka - UDA - So I assumed its a SRC...

But his complaint is that he hear both effected AND DRY from the mic... so its working...

Russ

Right, but if it is a SRC - Mic connected to rear of the card (older ProFx), then it would be effected by the "MIC In" slider on the AC97 page of kxmixer (i.e. hearing both Wet/Dry at same time in speakers (but this would not effect recording unless you are recording stereo/mono mix)).

Maddogg6

ahh - I did not know this was true for older profx... edit: I thought it was card - not proFx version...

When did that change?

Russ

It is still the same, except all AC97 stuff was moved to ADC, but the controls on the AC97 page of kxmixer still effect it (that is why when using ADC, you should not touch the AC97 page of kxmixer at all).

PurpleMoose

OK I can post up MX6, but what's ADC?

Oh yeah and the card is SB Audigy 2 1024

Russ

You are using an old version of ProFx... ADC is a plugin that comes with newer versions of ProFx (I wasn't sure what the plugin labeled "MIC" was, nor how it was configured).

In any case, one problem that you have is what Maddogg6 stated, you incorrectly have MIC enabled for the Main output in MX6. Remove the check in the box labeled "M" for IN4.

Also, if your MIC is connected to the rear of the sound card, then verify that the MIC In slider on the AC97 page of kxmixer is muted.

I highly recommend that you download and install the current version of ProFx (see the sticky thread at the top of this forum).

PurpleMoose

OK, I downloaded and installed the new driver & the new ProFx. I'll goof around with this now and see what happens. One thing I was curious about was that the new installation of the KX 3539 Driver queries for the path to your VST Plug-ins. Is there some kind of host mode or what? Why does it want to know?

Maddogg6

kX installs 2 VST's (VSTi if I remember correctly)

kXi and kXSFi

Neither are *needed* - just gives some extra conveniences in a DAW host.

PurpleMoose

Yes -- I continue to have this problem. Both wet & dry come through the speakers.

I even tried this very simple setup...

Picasa Web Albums - Purple Moose - Tech Stuff

The VST host is Cantabile Lite. Src is renamed for clarity. I still hear the original dry mic input along with the wet.

VSTHost (the open source thing) does not see my KX setup at all.

I consider myself a pretty smart person. I've been doing MIDI programming and stuff for a long time. The KX driver is awesome in so many ways. But this particular config just totally baffles me. I am completely dazed & confused by what might be happening. Any help is greatly appreciated.

Russ

How is the MIC connected to the sound card?
How is ADC configured?

Assuming that the MIC is connected to the rear of the card (as opposed to a drive bay):

Use only the top 2 pins of ADC.

Make sure that nothing (with the possible exception of the +20 dB MIC Boost option) is enabled (blue) on the right hand side (Mixer section) of ADC's GUI.

On the left hand side (Recording section), MIC should be selected in both drop down boxes, the Enable Rec Source button should be enabled (blue), and the slider should be adjusted as desired.

It is still unclear if you hear that Dry signal passing through your VST Host software or
hear that Dry signal 'leaking' through some DSP hardware path.
So do a simple test;
Use the latest DSP setup you posted,
start up your VST host.
Now, according to you, you should here DryMic + processed sound. Right?
Ok, now close your VST host and speak through the Microfoon again.
Do you still hear a DryMic sound comming out of the speakers?
