I am looking for a multichannel USB data aquisition board (DAQ) that will work more or less immediately with max - I want to get a stream of numbers in realtime measuring my signal with the minimum of faffing around - though I would like to add a filter. I would also like it to have at least 1000 hz sampling rate per channel .Here is an example though I dont know if it works with max :

PS I do not wish to use an arduino for various reasons

It looks like if you want the DI-149 to work faster than 240hz you have to pay an additional 195usd?

Teensy? http://www.pjrc.com/store/teensy3.html

Cheers. maybe this would be a better example :

1. I am measuring very tiny electrical impulses - typically 40 mv above a background noise of 20 mv - but I will probably use an instrumentation amplifier to boost this.Can the Teensy do this (eg does it offer differential inputs) ?

2. What is the sampling rate and is this divided amongst the channels ?

3. How do I get the channels into max as seperate streams ?

1) from my experience you'd be best off by amplification before hitting the device - thankfully amplifiers are extremely simple things.

2) dunno, you'll have to look for the docs.

3) see 2 - this is a fairly normal thing to be doing with these devices, so there should be precedents.

Some products here can sample at up to 50 kHz:

yes I have been looking at Labjacks stuff - its definately fit for purpose - how easily will it be to get the data into max though ?

There's an external for the U12 model here:

Seems quite old but it's MacIntel-compatible however...

@Roald - that looks perfect but ... I am using a windows PC - any other suggestions ?

(don't say it - just....don't)


noone got anything working labjacks or NI gear ?

USB Data aquisition board that works well with max msp ?
