Setting Multiple audio inputs in Max
I am currently working with a patch the has three separate inputs working to trigger one video. My problem is that I can only get Max to recognize one input.
I rented a digital mixer to try to hook up the three inputs that way and see if max would take it as an external device that could recognize three separate channels, but instead it still only sees it as one single device and not three separate channels.
Does any one have any insights? Suggestions? Is it my sound card? Is it a problem with the patch?
I have no idea, and any help would be greatly appreciated.
I possibly had a similar problem – (outputs not inputs but its probably sound card related) I wanted to do surround sound in max and had a couple of soundcards – i asked my lecturer and he said max can only deal with one sound card at a time, so i would need a single card which did all 5/6 channels.I guess you would need a single audio interface capable of inputing 3 channels and then it would be possible.Was the digital mixer a sound card as well?
I’ll have a more in depth look at it tonight sometime and get back tomorrow if I find a way of doing it.
hope this helps,
yes first you’ll need a bit of hardware that can physically send 3 audio inputs (6 if you are using stereo) into your computer as max can only handle 1 audio driver at a time.can the digital desk do that?I guess you are using the adc~ to get the audio into max.if you double click on that object to get the dsp status window you can see how many channels of audio your driver/hardware is capable of, and at the bottom of this box is the I/O Mappings button.Hopefully if you click on that you can see all the inputs and outputs selectors…
Anyway…if you open up the MSP tutorials pdf in the documentation theres a section called Audio I/O which can probably do a much better job of explaining than me!
if your sound card does only do stereo you could always mix the audio into frequency bands/mono channels so it only takes up 1 stereo input, then use max to deconstruct the signal for using as triggers.You would have to take the audio you listened to out to speakers before it went into max though, as after it would be sounding pretty bad…
As i said before, the tutorials know alot more than i do.maybe tutorial 13 also.
hope this helps,
If you’re working under Windows, try the free driver ASIO4ALL.
With that, you should be able to see all of your audio cards as one with
several inputs – but only if your cards have MME drivers
