Hello,
I have a Sound-blaster Audigy sound card with midi I/O add on card.
I have had the same set up for 5 years now but today I found I lost my left channel.
My question's are; 1.) Is there a way to test the output coming out of my Casio WK-3500 to determine if it's the keyboards output.
2.) Is there a way to test the sound cards input to determine if its the sound card.
My set up;
ASUS A8V deluxe
AMD 64 bit 3000+ processor
1 Gig dual ram
Audigy sound card w/I/O
Sonar Producer 3
Casio (Don't Laugh) WK-3500

I have checked all cables and even hooked up new cables to test.
I can record MIDI as usual (both Ch record), But when I go to record Audio via the line in/out
I only get the right channel.
I ran Creative's Audio trouble shooter and it passes every thing as being OK!

So back to my question is there a fairly simple test to see if there is out put from the keyboards line out?
Thanks and have a Great Memorial Day weekend.
Regards,
CC
 
I'd just plug a headphone jack into the Right and then Left outputs of the keyboard and see if there is signal.
 
Thanks for the reply,
I have a single stereo headphone connection and off the keyboard get both channels. I have one right and left Line out's! And need to know a simple way to check them IE; headphone a signal checker etc.

I hooked up a head phone to each of the outputs (one at a time and got a good signal on the right and very weak on the left, so does this mean my midi controller is toast?

If I plug into the PC head phone jack all I get is the right channel "NO" Left.
I Ran RMAA 6.0.5 and it says the output signal is weak and to adjust the mixer, I have done all this to no avail. I have a friend who has a know good but older sound car and will try that next next week if need be. I'd rather replace a sound card than a midi controller!

That's what I meant by checking the output with the headphones, one at a time.

You need to deal with each issue separately. The first issue is if the keyboard is outputting the same volume on both sides. From what you are saying it isn't, but you need to make sure that the patch you've selected is not panned to one side or the other. In other words, select a sound on the keyboard that you know outputs equally to both sides.

If it is still outputting less sound to the left side then you know there is a problem. It could be any number of things, and might require a trip to the repair shop. what keyboard is it?

As far as the sound card, you need to deal with that individually as well. Each channel should be tested by itself, and using a sound source that you know is correct. For example, a test tone. Or you could swap the cables from the keyboard and see if the problem follows the cables or stays where it is. In other words, put the left output of the keys into the right input on the sound card, and the right output of the keys into the left input on the sound card.

It's the process of elimination, and attempting to isolate each element that could be at fault.
 
Hello,
OK I did hook up the headphone and test each output L/R and heard sound, I then adjusted the volume to high and low and could hear the level change; but even with the volume all the way up the sound was low. Pan set to 00.
Should the sound output from the line out be the same as when the headphone jack is used; in other words very loud?
I checked the spec's for the headphone and line outs and there rated at 3k impedance and 1.5V RMS Max.
So that leads me to believe that I should hear the same volume level at each output; am I correct in that thinking?
But I still think it could be the sound card as if the keyboard has sound on both channels then the PC should record both. I am thinking of using the headphone output to hook to the line in on the sound card and attempt to record and see if I get a signal on both channels.
Unless you don't think that to be a wise idea LOL.
I did run RMAA 6.0.5 and it said the levels were to low and to adjust the mixer levels which I did but I still only recorded the right channel.
Oh! the keyboard is a Casio WK-3500.
Thanks,
