M-Audio 2626 - Possible to save the internal mixer routing?

[777funk]

I can save it in Windows but when I unplug power and power it back up, the routing is gone until plugged into a computer again. Is there a way that it can be made to work without the computer with the settings made in the M-Audio application?

Not too sure about that. I recall the options for standalone mode were A/D or A/D&D/A, but don't remember whether there was a third option, which may or may not use the mixer settings.

Focusrite Saffire 40 definitely has a "save to hardware" option (i think it used the same Dixe chip...?).

So it's saving the settings to the Dice chip?

What is the CMOS used for?

BTW, I'm pretty sure MAudio designed this unit so that the settings cannot be saved to the hardware. It resets to default (In 1 > Out 1, and so on) upon power down. I looked through the software menus. Pretty sure it cannot save the settings to hardware itself. It repulls the settings when the computer brings it back online. In my case, that's no good because I am using this in Linux. So no stock software unless I boot up an old laptop to bring it back to my settings. Thus the attempt to get it to hold the settings upon power down. Of course I could just keep it 12V powered on a UPS, I suppose so that it never "forgets" what I have set up in Windows (or in FFADO mixer from Linux).

No, the Dice has no internal (non-volatile) memory.

And what "CMOS" do you mean?

Ok thanks. This chip:

And the same basic setup, but this on my FW610 interface. Looks like they re-use some of the 410mkII's guts (PCBs, etc) in the ProFire 610.

That's a flash memory chip, it's non-volatile "already".

Why wouldn't they have? Same "brains", just different amounts of i/o...

The 410 is pretty similar I/O. just cheaper than the 610 (not "Pro"fire). I don't think it has THAT1510 pres (not that THAT's are that expensive).

That's a flash memory chip, it's non-volatile "already".

So that begs the question, what needs to be kept alive to hold the memory for the configuration? I suppose I could take a shotgun approach and keep the 3.3v entire line held up by a battery. So flash shouldn't need any voltage to hold its contents. Is the Dice chip the forgetful one here?

Maybe here lies the problem..

I suppose no modification would be just to:
1. Reload settings from Windows every time it's to be used.
2. Use a 12VDC battery and a float charger to keep it always on.
3. Use a UPS
4. Buy an Echo Pre8 (very similar to this thing, but stores settings upon shutdown).

But I may crack it open again and see if I can keep alive whatever logic side needs to be kept alive. I didn't see a store data option for the Dice data sheet above. It looks like it would be pulling 700mW at idle. So at 3.3V that's 0.21A. I'd doubt a coin cell could even do that much less hold that current/power any length of time, so maybe my coin cell idea is out.

I have a couple of interfaces that don't officially have standalone mode, but if I set it up with a computer, then disconnect it, but keep it powered with an external supply, the settings remain until powered off. That way I only need the computer for setup, then can disconnect it and put it away; they'll work w/o a computer as long as they remain powered up.

This is how I use the Fast Track Ultra and Focusrite Scarlett 8i6.
