needing a stupid amount of audio outputs.
I’m needing to 36 synchronised audio outputs to control an installation.
I’m wanting to send control voltages instead of straight audio signals. In other words, I’ll have to customise the cards so that they pass DC offset.
This means using a nice expensive audio interface is not on.
What are the chances of me building a PC and putting in a series of cheap surround sound cards instead? Would feel more inclined to attack these with the soldering iron.
Can I run multiple sound cards in sync on a PC like this?
Does the multiple soundcard issue only apply to Macs, or PC’s as well?
Dim Mac User.
Since you’re dealing with CV, why use audio interfaces at all? I think you could simulate 36 analog voltages with something like a Gluion:
using PWM on the digital outs.
BTW: Not all audio interfaces block DC on the output. Someone on this list mentioned that the MOTU 828 does not.
i would recommend you to use cards which can
run with the same driver software.
ASIO link or virtual coreaudio drivers is too unsafe.
a combination of motu 828 and motu 24 IO would give
you what youw ant, not sure if you count that as
yes, the gluion can create up to 66 PWM signals (which can be
synchronized). But it depends on what you want to control in your
installation, e.g. motors and lamps work fine.

Working with a friend’s motu 828 mk1 at the moment. Because of the DC offset ‘feature’. But In Australia MOTU is still expensive, and only half the ebay sellers will ship outside US.Was wondering aboout those really cheap surround soundcards though. You know,the $50 soundblaster kinda thing.
We’re using 48k frequencies so gluion probably not going to work.

Does this mean that as long as they are all the same, they can all be accessed by Max on PC at the same time?
