getting data into max

August 23, 2006 | 8:06 am

I am trying decide whether to get data (generated by a proprietary sensor system) into max via midi or via some other way (e.g. creating a file outside of max, and reading a file when in max).

as I am a novice at max, I am not aware of the best ways of getting max’s hands on this data. so any advice very welcome.

It will need to run on a pc (running Windows XP Professional), and with the software extracting and preparing the data also on the same pc. The proprietary sensors software seems to need a program written in C to get access to teh dat, but we are experimenting on a simpler way (as the project doesnt have any ‘C’ skills …. )

I would like midi coming into max, as easy to handle … but 2 problems:

1. getting midi from other software into max on same PC (e.g. midi yoke does it, but apparently a bit ‘flakey’ on NT/XP…!)
2. knowing how to generate a midi message from C or similar …

an alternative is by writing to a file in some front end software … and then reading that file in max

or

maybe another (better) way that I dont know about ..???

any helpful comments/advice out there …??

p.s. I normally work with max on a mac… so yet another layer of mystique in sorting this out ..!!

You can use a serial connect, USB HID via the hi object (either your
own system, one that someone has built, or things like hacked game
controllers). I’m sure there are other ways, but these 2 are quite
common.

Whoops, didn’t read the second half of your email. I was thinking you
were going from a microcontroller to the PC. For software to software
communication, sockets is the best option. I have no idea about your
software, but if there’s someway you can use it to send data of UDP or
TCP/IP, that’s the best thing. Otherwise, if you can get it to write
to a file, max can be made to automatically open it and parse it quite
easily with and mxj or js object.
