The problem is this: I have Audigy 2 Platinum Pro, which has a very nice noise removal chip built in to hardware (works just perfectly for my synth''s very noisy output). What I want to do is record stuff live with the noise removal enabled (so that the source is Line-In) while listening to what I''m playing on the keyboard as well as to the background played from the PC. Here''s the catch: the noise removal has a latency of ~1 second, which makes it impossible to do stuff in realtime when hooking the audio system/headphones to the sound card rack. However, when I connect the headphones to the keyboard, connect the line in and line out of both the keyboard and the sound card, I get feedback. Plus this feedback is carried back into the signal being recorded. This leaves me with one option only: block Line In from being redirected to Line Out. I need the Creative drivers to be installed (because the noise removal only works with the Creative Media Player and that requires Creative''s drivers) so I can''t switch to kX drivers either (to be honest, I cherish the simplicity of the Creative drivers and really don''t want to switch anyway). So, with all that said, is there a way to do what I just asked because I can''t find it? PS: true, I could always re-record the recorded noisy signal and have the sound card purge it in post-processing since there''s a one second delay in recording anyway, but the point here is principle: why to it the obvious way?

alright, after alot of thinking I finally figured out what you''re trying to do (damn no coffee in the early morning!!).

The studio term for this is "monitoring upstream". You want to listen to your live track before it hits the recording device (very unkocher, but take what you can get eh?). The key to removing the feedback is in your keyboard somwhere. What seems to be happening to me, is that your line-in on your synth is sending it''s information to the line-out. There should be someway to stop this the settings (depending on how new your synth is)

Failing that look to your computer. I don''t see why the guys at Creative would be so stupid as to create a soundcard with the ins hard wired to the outs (though I wouldn''t put it past them). Check where your inputs and outputs are in your recording program. Make sure nothing is in a spot where it could possibly loop with the keys.

ie, make sure that the track you are recording your synth on has no output. You are already monitoring at the headphone outs, if you send the signal back to the synth, thats definetly where your loop is.

I hope I made some sense. Or just laugh at me
