Hi guys,

Looking for a way to programmatically control each channel's output level I stumbled in to the kxproject. Allthough I haven't given it much time to try and figure it out myself, I was hoping someone here has allready done this....

I've written a vb app for my carpc (www.namms.tk) but I want to have a fader control, so far I haven't been able to do this, but I figured the kxproject would be the way to go as they have an SDK and creative won't let me download one.

My C++ capabilitys aren't very good, so I was hoping to set the channels by using api calls from VB to a DLL from the KXproject, but so far without any succes....

can anybody help me???

you will need to create a special 'wrapper' for calling C++ code (DLL-based) from your VB modules
please search the internet for details since this task is not really kX-specific

Sorry to keep pesterring you, but you guys made me so happy and now my own lack of intelligence is keeping me from doing what I want to do...

Yesterday I searched all day to figure out what a wrapper is but couldn't find an answer.. Is it a DLL that calls your DLL sothat I can call routines from VB? so VB calls my "wrapper" dll which calls your dll?

For setting the sound volume of each channel I'm searching in the exports of KXapi.dll. Am I looking in the right place?

I understand that what I want is not in the scope of your project, but as I said before I've been trying to get a fader option in my carPC app forever and was soooo happy to see your efforts...

download the SDK, you will find 'kxapi.lib' import library
now, browse Visual Basic help -- search the topic for 'using C++ DLLs' or similar -- since I haven't got any VisualBasic experience, I really cannot guide you

it would be interesting to see a decoder or plugin, that would allow any programming language to interface the DSP

such as activeX?.. well.. probably, yes -- in the future -- anyone interested can start coding right now
