Avid and TC Konnekt make 6-8 channel interfaces with analog volume control.

-Jim

You'd need four or six channels of analog volume, that's the catch.

I was pointed to this today, might be of interest: http://www.bodziosoftware.com.au/

Hi Jim - do you know which ones specifically?

[JDUBS]

John, definitely the Konnekt 48 from TC and the Avid Mbox Pro 3.  I've owned both and the inclusion of an analog volume control was a big part of the buying decision.

i assume its the TC Konnekt 48

cheers

Hm, on their website TC Konnekt 48 says is has analog volume only on the main outputs.

Jim, on the Mbox Pro 3, the master volume control controls all six outputs? Can't find anything written about it anywhere! Interesting what different purposes it's intended for than what we want to use it for.

[JohnR]

Re-did the crossover to use Pro-Q for all EQ. Much more convenient than having lots of little AU interface boxes popping up. Here's "today's" EQ curve (it's a dipole)



The interface is a bit noisy, gain structure needs some work. Next time I get a chance to work on it I'll look at that and try using Pro-Q on individual output channels.

That's sweet!  Wish the miniDSP had that type of presentation for EQ.

John, the TC website doesn't speak to clearly to the feature, but check out the 6moons Spatial review.  The fact that the digitally controlled analog attenuation doesn't work in 24/192 was something that came up in the review.

Nice!!  Pro-Q is a great plug-in.  Very easy to use.

Been late to followup on this one. I've now got ProQ running separately on each output channel, plus another instance running on all channels. Some issues trying to switch them all to linear-phase... not got a good enough handle on them yet to post much about it.

So I finally "won" an external dac, a Motu 828 mkII.  Came close a few times, and I snagged one yesterday.  Should get it in a few days, and will start playing with it.  I already bought a calibrated mike, so I can start making some measurements.

Awesome    Very interested to hear your progress with it.

wow! Pretty neat that you can do that.

It is I've now gone "headless" (remote by iPhone Remote app only) just to try and push the whole thing a bit and so far it's been fine with several instances of Pro-Q running within PM in zero-latency mode, although there seem to be some issues when in max-latency linear phase mode. I haven't really figured out why at this point. I'm going to try just a pair of Pro-Q instances, one for driver/baffle correction (*), and one for "room" correction, and see how that goes.

(*) As long as the drivers are not too badly-behaved outside the passband, the results should be pretty close.

So I have been playing with my Motu 828, trying to figure things out.

First, I had to buy a new firewire card, I had a PCMCIA one, and my laptop needed a EC interface, so it was off to ebay.

I can talk to the 828, and it seems to see music (haven't actually hooked it up to anything yet), so that's good.

I have a license for allocator, and that looks like it should work fine for the crossover, seems to be pretty straightforward to setup to output multi channels to the motu.

Problem right  now if feeding music out of my PC straight into allocator.

I just found this thread
http://www.thuneau.com/forum/viewtopic.php?t=168

which describes using a program called Jack to allow me to feed stuff to allocator. 
I was also looking at "virtual audio cable" and something called "rearoute" which is part of reaper.  The last two are not free, VAC is around $50, and reaper is a little more.

I have already played with VAC, and couldn't get it do to what I wanted, at least not in my 30 mins of messing with it.  Both Jack and rearoute have been used with allocator, so I should have better luck with either of those.

Randy, I would try Jack for sure.  I had a lot of success using it in conjunction with Allocator.

Cool.  It seems a little complicated, but that thread has some pretty detailed instructions for setting it up, so I think I can get it going.

Yes, the thread makes it seem more difficult than it is.  The batch file is useful once you get the setup up and going but you don't need to worry about it until the very end.

I'm happy to help with any questions you have along the way.

I have been messing with it for part of yesterday and today, I can't get jack working right, seems like it doesn't get along with the Motu Asio driver.  This might also be because I'm running Windows7, I'm guessing it's may have to do with this specific combination, but it's what I have to use.

I may give up, and go work with reaper instead, that seemed to work OK.

Randy

[randytsuch]

I think I figured out that I was making it more complicated than it needs to be.

I can run allocator as a VST plug in, in either Foobar or JRiver.  I am leaning toward JRiver right now, Foobar has a problem where I can only run it once, and then I need to reboot my PC before I can run it again, if I have the VST plug in , and the ASIO plug in installed.  Kind of annoying.

I need to make sure I can route the signals with JRiver, will try that tonight.

I think I could also make this work if I used Reaper with Rearoute.  With Reaper, I can run Allocate as a plug in, or I could run it standalone, and use rearoute to map the ins and outs for Allocate.  The Jriver plug in route is much easier to set up, so if that works I don't need to mess with Reaper.
