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!!!

Hmmm, that patch is very complex and you clearly know more about programming than me. What is [comport] for?

Anyway, for trouble shooting purposes, try a very simple patch that just focuses on using the makenote object successfully to send your noteout messages. Or, to troubleshoot your patch, put a [print] at the end of your noteout objects to verify that they are outputting.

Use Jack to connect PD to Protools. Both apps are probably confused and sending info the same direction.

The IAC driver has sixteen channels. So [noteout 1], [noteout 2], and [noteout 3] are sending to channels 1, 2, 3 on your first IAC driver. To use the multiple MIDI devices in Pd, you keep counting up from the first sixteen channels. So IAC 1 would be channels 1-16, IAC 2 would be 17-32, IAC 3 would be 33-48, etc.

Why do you need multiple MIDI devices?

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. =)

Hi.

I am new to his forum, but not new to pd.

I used to make pd patches with 64 MIDI outputs divided in 4 output devices. Now I have a new computer with Win7 64bit, and pd shows only 2 MIDI output devices, although I have 6 connected. How can I configure pd to talk to more than 2 MIDI devices again?

all the best for all!

I believe you have to do it using a command line flag:

-midioutdev 1,2,3,4

That will use your first four MIDI output devices. You can add it to the startup flags box in the Startup... dialog.
