I'm running two separate instances of PD in order to utilise both GEM windows as I have the GUI for a monome on one and then a (very basic) graphic accompaniment on the other. An attempt at digital harmony. My problem is that I need to get lists from the monome patch of midi note numbers dynamically as they change and receive them in the graphics display patch.

I have been using [udpsend] to successfully send other data between the patches but these are 8 discrete floats and are taking up one UDP port each. I also need to send 8 variable floats and wondered if it's easier to set up 8 more UDP connections or if I can send this info as a list. The former seems like it should be wrong but I can't for the life of me figure out the help patch and translate it to my work.

Any pointers much appreciated.

I don't know about udpsend...

But if you really run up against a wall, you might consider something different, like MIDI CCs.

Thanks for the responses guys.

shawnb, What is the object for use with MIDI CC? Never heard of it before.

Gromit, Thanks for the example. I'm having a go at including this in my patch today and will let you know the results.

Cheers.

[Ctlout] and [ctlin], IIRC... Specify a channel, CC# & value. Old school, but works. Most prefer osc today, but if talking with commercial hardware or software, midi is still widely used.

You will need to specify your midi devices. Since you're all on the same box, I'd recommend looking up loopmidi, a freebie utility that simply pipes its inputs to its outputs. Make it the output midi device for the instance spewing [ctlout], and make it the input midi device for the instance expecting [ctlin].

Gotcha. Nice one. Will try it although think I may have resolved the issue with Gromit's solution. That was until PD weirded out and stopped computing audio for no reason I can see. When I figure out what I've goofed up I'll see.
