Hello,

I'm looking into the options for electronic I/O with modern macintosh computers - specifically the Mac Book Pro with USB2, FW400, FW800 and Express Card ports

I'd like something that could both read digital pulses and output them with some kind of easily accessed system wide interface that could be incorporated into other applications (with a little scripting I guess) - specifically Matlab, Maya, Max/Jitter but my own creations also.

Pretty much the modern version of the ubiquitous PC parallel port stuff from not so long ago.

some more criteria:

It would use an established 'plug' - USB or firewire most likely...
It will have higher resolution/sampling freq and lower latency than MIDI/DMX
It wont cost mega bucks or have a mega bucks program required to run it (NI Labview etc...)
It would have helpful documentation for beginners as to how to access it via code

I'd like to try to avoid converted/hacked systems which tend to fail on you in unexpected ways ... But am still keen to hear about them in case that is all there is...

One immediate project involves recording encoder pulses to file (I'm thinking of using an audio recorder then converting the audio to pulses in MSP but that is an example of a 'hack' and also where digital I/O to MIDI/USB just wont have the speed)

What are the Macintosh options ?

Any help appreciated !
