soundcard w/ more then 24 outputs_any idea ?

January 25, 2006 | 5:21 pm

hi List ,
I will be working for an artist whose intent is to display sound objects from 144 speakers.
therefore with my collaborator we are looking at the best solution in terms of soundcards. Of course we are not hoping to have one channel per speaker, but we still try to figure out the best solution.
we will probably using a G4 tower ( w/ OSX 10.4, max/msp 4.5.4 ) since the installation does not require that much MSP process other then just reading small soundfiles and dispatching them through various channels.

we are thinking in investing in the 24i/o MOTU interface.

does any one have another suggestion or advice ?
quantiy rather then quality being the goal of this piece.

thanks in advance, i have been trying to find the answer in previous threads but could not find satisfaction ;)

One way is to use a matrix system which is basically panning your
input mono/stereo signal to 8 speakers based on a control signal. One
example is this box (only 128 outputs, though):

With the pci424, you can plug "only" 4 motu 24i/o, and anyway, the
pci424 manages only 96 channels.
But you can also try to add firewire interfaces and do an aggregate.
Curious to see wether OSX can manage so many outputs.

I once worked with 2 motu interfaces, and it seemed I had access to all
28 channels without any problem.

Hello Karl

At BEAST, we have often done 4 x 24 i/o (96 i/o) on one single
pci-424 in a g5, without any problem. Lots of pleasure, no hasle,
all the drivers behaving perfectly. Not cheap, but really reliable.

good luck

ps CoreAudio sees it as one 96 in/out interface, which simplify the
task greatly.

Hello,

i would suggest to use any MADI solution. Advantages : 64-128 tracks /
BNC for not so much money, long long long long range available (not like
adat), handy. The RME HDSP MADI is the best i could advice you. You will
have to rent a mix console that has a MADI option, but all digital
Yamaha’s can get the optionnal card for MADI handling and it’s not much
in the final bill (if you’re not buying it, of course !).

best regards

I forget to tell : if you’re on a laptop, there’s an adaptater that
works to plug PCI with PCMCIA…

cheers

If I remember correctly the motu’s can be linked, they even promissed
at one point that when a musician needed more in/outs then the linked
motu system could deliver they took the guy out for dinner (and I’m
not kidding)

From the old Emagic Unitor 8 manual:

"If one fine day you should discover that 16 Unitor8 units are not
sufficient anymore, we would like to treat you to dinner in order to
find a profitable solution together."

[= 2048 midi chans, 16 Unitors via 2 serial ports on old Macs]

MOTU/audio linkage more modest, I fear…

thanks for your advices,

the RME solution seems attempting , could you give me more info on how it would work on the msp end .
would i have to control the mixer through midi ? or do i use the dac~ in the same way i would with a regular firewire soundcard.

( dac~ 1 2 3 … 96 ? )

i have never worked with an RME Hammerfall HDSP MADI 24/96 128 Channel PCI Interface before.

thanks

the dac~ solution is the way to go
– in the old days (that is OS9 on mac, and max…. some old max,
maybe 3.xxx) there was a possibility to control the internal mixer of
the RME from max, with a special max object, but (as far as i
understand) since RME did change the internal architecture the old
code does not work, and RME never answered mails asking for the new
implementation – i found a developer (Laurent Pottier) ready to write
a new object, but we never receiced any answer from RME
