I am trying to write a patch to control ableton live with a monome 40h.

I have input device 1 in PD as 'from monome serial io' and output device 1 as 'IAC 1' (which in turn is set as the midi input for live), which works fine for controlling live with the monome.

I have midi output for live set as 'IAC 2' and input device 2 in PD as 'IAC 2' and the output as 'monome serial io'. I can not get the LEDs on the monome to react to live.

My question is how do i select different devices within PD. I can only get input and output device number 1 to work together.

I seem to remember that in MAX/MSP you can add the relevent letter (a, b or c etc) to the 'notein' object box to select the device. Can this be done in PD, if so how?

I know live is definatly giving out controller messages as I have -midinotefeedback- turned on and if I change the order of devices around in the midi settings I can light LEDs on the monome by moving sliders etc within live.

menu: media -> midi settings

Is that what you meant (rather than channel)?

No,

I have 2 input devices and 2 output devices set up. So that PD is between the monome and live and there is communication in both directions between the two.

I can only get live and monome to communicate in one direction at a time. Either the monome controlling live or vice versa.

How do i tell PD which device to send and recieve midi data. In MAX/MSP you just add the letter that is assigned to the device into the 'notein' box to select that device. How do I do it in PD?

I understand. Sorry to bear bad news but as far as I know Pd is limited to one midi device.

Perhaps I'm wrong (I'm not much of a MIDI expert really Adam)

Is there some way we can make this work using splitter/mergers and channels?

PS you lucky bastard, how much fun is the Monome on a scale or 10 to 11 ?

In windows in the MIDI settings... there's a tab called 'Use multiple devices'. I haven't tried it yet, but I presume it allows you to do what it says...

I am also intending to use more than one MIDI device, so I hope it is possible on my macs, but it seems some of the MIDI objects are Linux Only. For example the help file on [midiout] states that the 2nd input is for port number (thus you could direct your data to MIDI device of your choice) but that it is Linux only.

I'll let you know my findings when I play around with it later.

Ah yes! Nice one Brett.

I've never used this but now I realised why it only ever shows one device.

There's some start flags you might need

-midiindev ... -- midi in device list; e.g., "1,3" for first and third
-midioutdev ... -- midi out device list, same format

(edit)

Just tried it but no luck on Linux (OSS MIDI), maybe you'll have better luck on Win

(edit)

Tried again with ALSA MIDI and all looks good

[notein 1] and [notein 2] seem to be connected to different channels.

i've often sent and recieved with multiple midi devices. What pd does to multiple devices is kind of odd; it adds 'virtual' channels. If I have my GR-50 in mono mode transmitting on say channels 11-16, they show up as such. However, If I have my Oxygen8 set as the primary device, and the GR-50 as the second, the GR channels actually come across as channels 27-32 (11+16 - 16+16) Does this makes sense?

IOW; Device #1 is Channels 1-16, #2 is 17-32, etc....

Also, if you heve a mac, get midipipe... . It is great for routing midi messages and has a midi monitor which is invaluable for this sort of thing.

Nestor,

Thank you that works, I was looking for something more complicated. Did'nt even think to check channel numbers.

Obiwannabe,

Got my monome kit and built it in the week. Really impressed with it. As soon as I get it talking to live the way I want much fun is going to be had.
