hi im using the CT4760
i have some gear connected to the line in on the card with a src module.
i add another src module and make that mic/lin2, the panel on the live drive and then all of a sudden the line in on the back stops working. does that mean that i cant use them both at the same time?

Well since I have a 50/50 chance of being right in answering this, I would guess that you would need an Audigy card to be able to use simultaneous inputs. Now maybe someone who knows for sure will answer.

laserbeak

i hope someone has an answer. i still need an outboard mixer anyway though

Im pretty sure Doug is correct, the line in and mic in on the back of live! cards can not be seperated. It can on audigies. (kX command line command that splits them)

The line/mic2 SCR represents the input on the live drive.

Im not familiar with this particular model (Ill guess its an SBLive)

But on my A2zs plat - I can set 1 profx/src to a AC97 input - and at the same time have the Mic2/line2 set to another profx/src - The ONLY issue is when using 2 AC97 sources at same time - which I beleive is a hardware limit and not KX bug/limit - btw.

If I have 2 profx/src - each set to a different AC97 source - the last one I change will affect both src plugins - as both profx/src's will output same signal on both.

Thats is how it works for me with KX3538h in winXPsp2.

To best answer your question - it does NOT seem that simul multi inputs work with that card model as it seems your card is using the Mic2/Line2 as an ac97 source where on my card its NOT ac97...

Hope that helps.

Let me add to the 'confusion';

1. Every kX compatible card has at least 1 stereo analog input device
namely; AC97 device.
You *can* get seperate Line and Mic signals (in MONO) from that AC97 device if
you use the ADC plugin from the latest Profx Pack.

2. A LiveDrive adds at least 1 analog input (with better codec btw),
which can be used simultanious with analog AC97 inputs on the back of the card.

3. Audigy cards have a second Analog device (UDA) besides AC97.
In that case you can get 2 seperate stereo analog inputs from the card.
Use the ADC plugin from the latest Profx Pack to enable UDA device.

4. Bundled versions of SRC have a 'bug'.
Every time a new SRC is added to the DSP it will default to [ac97 mic],
thereby 'resetting' a previous SRC set to an AC97 source.

This is all 'out of my head', so consider it as AFAIK!

The above statement is a little confusing, can you elaborate on that a little?

Do you mean that a LiveDrive adds another AC97 input source (i.e. using same AC97 codec as MIC/Line In on back of the card)?
or...
Do you mean that a LiveDrive adds a seperate AC97 device that can be used independently of the first?
or...
Do you mean that a LiveDrive adds an additional (non-AC97) input that can be used independanlty of the AC97 device(s)?

The word simulataneous is a little confusing. i.e. Simulataneous as in independant of the other inputs? or simultaneous as in can be used at same time as other inputs, but mixed (as with the MIC/Line In)?

Also, the "with better codec" statement, makes it sound like it is either a seperate AC97 codec, or some other codec, which would seem to imply that it could be used independantly from MIC/Line In, etc. The sliders on kX Mixer's 'In's and Out's' page, also seem to indicate this, as the 'Line 2/MIC 2' slider is seperate from AC97 (as is the connections on 'prolog').

Does the card model make a difference here (or is it just a LiveDrive thing)?

If they are seperate sources, shouldn't you be able to use both of them independanlty using 'prolog'?

Sorry for the questions, but I do not have a LiveDrive myself (but kX mixer does include all the extra sliders even though they appear to be of no use with my card), and have been curious about their functionality (and that of the LiveDrive), etc. I had always assumed (based on the layout of kx mixer and prolog), that Line2/MIC 2 was a non-AC97 input, and thus could be used independantly of AC97, but have no way of testing it, so I could never be sure. In any case, I know your answer was just from the top of your head, so if you cannot say definitively I understand. Also, if anyone else knows, feel free to add your info as well.

Thanks,

That's right, at least that's the way it works for me (with to live drives on two different machines). If you have the live drive II ( the common model, I believe), you also have the aux2 as an independent stereo input.

So basically the ct4760 should behave in the same way as the audigy cards (see post from Maddogg6)

Russ

Thanks for the info

So, laserbeak's issue is just from the bug with the bundled 'src' plugins (3538i), and he should be able to do what he wants using 'prolog'.

Lex Nahumury

>>Do you mean that a LiveDrive adds an additional (non-AC97) input that can be used independanlty of >>the AC97 device(s)?

Yep. That's what I mean. (that was/is the Q of the OP,.. right?)

Russ

Thanks, I just wanted to be sure that I was understanding it correctly (and I thought that if I was still a little confused, that the OP might be as well).

Lex Nahumury

Yes he probably is.
Anyway, that is no ac97 device on the livedrive.
It is not mapped in adresspace so nothing to program there like we can with ac97.
Data comes in through I2s on expansion connector.
Also, those 'LiveDrive' sliders in kx mixer are just controling some Prolog volume register in DSP.

Russ

Ahh, that is interesting. I had mentioned this before, but my card does not seem to have any way to connect to a LiveDrive (does not have the connector, and the board does not even seem to have the holes where the connector would go, etc). I had always wondered why that was, but if it uses the I2s codec, than that would make sense (considering my card does not have the I2s codec).

Maddogg6

In 3538h - this is not completey true/the case -

I can add another src (the first set to for example FP SPDIF IN) - and its true, it auto sets to the AC97 Mic - BUT, the first src is still set to FP SPDIF IN.

I ONLY see this behaviour when setting 2 different profx/SRC to 2 different AC97 inputs like LINE on one and AUX on the other (both which I use frequently) and am forced into swapping between the 2 frequently.

Russ

Yes, but you are using the latest ProFx with 3538h, right? LeMury stated that the bundled versions have the bug (I am not sure if he means only 3538i bundled versions), but I assume that means that the latest (non-bundled) version does not have this bug (and this would appear to be correct based on your observations. i.e. The behavior you observed seems like it works like it should work).

Maddogg6

I am using the profx that came with h (I may have installed newer profx for h that Im forgetting - now Im not positive)

I guess I was pointing out that I think Lemury meant to state.

Adding a second SRC will re-set other SRC's set to an AC97 device.

I guess the bug you mention is witnessed by how LeMury described the behaviour. correct?

Russ

Yes, you are right. I mis-understood. So the issue is that when you change one src plugin to an AC97 source, all src plugins, that are set to an AC97 source change as well (to that same source), and because the src plugins default to mic, loading an additional instance of src, results in all other instances that are set to an AC97 source to be changed to mic as well. I am not sure how else it would/should work, so maybe the problem is just that it defaults to mic (I guess it should not default to any AC97 source). It has been a while now since I used 3538h and the latest ProFx, so I am not sure how it changed in that respect, but I do not remember it messing up my AC97 setting (just by loading it), so I would guess that it uses a different default. In any case, that means that the src plugins should still work for situations like what laserbeak was trying, so long as you understand what is going on, it should be easy enough to work around.

Lex Nahumury

Yep that's correct and what I said/meant.
This will only happen with the bundled SRC versions.
Not with the latest skinned ProFx versions.

Here's the story;
Originaly when I first wrote SRC I set FXBus 0/1 as it's default value like it should be IMO.
Then, i think in the first 3538, Eugene added 'Presets' to SRC source code.
Since then the bundled SRC defaults to the first entry beeing AC97 Mic.

Although not a serious 'bug', and easy to fix, this can cause quite some confusion
especialy to new users.
Most kX newbie questions are I/O related as it is.

/LeMury

Lex Nahumury

None of the released ProFx versions
suffer from this 'ac97-default-reset' bug.
But since the addition of the ADC plugin this is no longer relevant since there
are no AC97 inputs on SRC anymore.

/LeMury

Maddogg6

Yes... this is why I was confused as its not a 'bug' IMHO - (I thought) its ultimately based on a hardware limitation anyway.

Is there an updated profx for h (with the ADC plugin)?

It would prolly been less confusing if the AC97 was in a seperate plugin than the SRC - Im guessing thats what the ADC plugin is.

Maddogg6

Yes, It does work for me - but did also confuse me at first and took a bit to understand what was going on.

Thanks LeMury - dont know how I missed this one - I guess I assumed it was bundled...

Its looking sweet thus far - but damn, now I gotta go and re-make all my DSP configs now- lol ... oh well, its lotsa fun anyway.
