I'm sure we're quite a number of max users,
needing that dammned 2nd output, to be accessible from max.
Here's a workaround, thanks to the vvvv community, and especially west and mfo users.
The second output needs to be enabled with some code, that i don't manage to program in max.
But this can be done, simply launching pro-manager (ENTTEC utility).
0-Launch PRO-MANAGER app
1- Select your device.
2-Go to the "send" tab
3-Output some data, on "both outputs 1&2" .
(for example, simply select "from faders" in the "source" undertab).
and it's done.
You should see your device blinking blue-yellow-green.
second output is now accessible from Max.
once you've done so,
you can use a serial object (with no attribute, it's working here)
and send :
for first universe --> 126 6 513 2 0 (512 values) 231
for 2nd universe --> 126 19 513 2 0 (512 values) 213
I'm adding an example patch .
If anybody here,
feels the ability to patch an "all-in-max solution" ,
that would get us rid of launching Pro-Manager,
please share it here , it would be so cool !
mfo and west (vvvv users) managed to do so.
here is a link to the file that enables it in vvvv.
The solution is in it, for those who can interpret the lines .
Cheers all :)
