Hello everyone, I am having trouble with the multichannel stuff.
Using MAC OSX, PD, Protools

I want to make a band playing (bass, Guitar, drums) at the same time using prottols as a shyntetizer.

I start PD, configure the MIDI output for the IAC Driver.
Then I open my Protools and I configure 3 MIDI channels and 3 AUX channels each with a sound.

Then I link the input for the MIDI 1 channel as IAC Driver channel 1, MIDI 2 channel as IAC Driver channel 2, and then MIDI 3 channel as IAC Driver channel 3.

And the outputs of the MIDI channels are directed to the AUX channels, that create the sounds.

I was trying to use the [noteout 1][noteout 2][noteout 3] to reach the different MIDI channels at Protools but without success.

Any better idea?
Thanks!!!

Thank you so much for the answers! Sorry it take some time for me to see because I live in japan (time lag) and I work during the day and study to my Master's degree at night. Which is the time to play with Pure Data!

Ponzo,
I will make a simpler patch, the one I uploaded it together with the whole stuff I need for connection with my Arduino and shock sensors, making it hard to understand.

I want to make a band with fake instruments, but using music patterns. So people can play in their own tempo. My idea is like a guitar hero game based on tempo, instead of notes.

Maelstorm,
you are great and I always learn a lot from your comments in the forum thanks for existing!

Tomorrow I will be able to use my equipment at university and then I tell you how it went. I will try everything you told me and add your names in my Academic paper Thanks. =)
