Okay getting somewhere, It works fine if I plug the bcf2000 into my midi interface with midi cables (why didnt i try that earlier!). It doesnt work for NRPN if i use the USB connection to connect the BCF2000 directly to the computer. hmmmm? buffers?

What if you send it the four messages manually in sequence instead of all at once? e.g. make a patch that uses ctlout and plug your MIDI out to your MIDI in. All I can think of is the usual culprits: buffer overflow or running status, neither of which should be a problem with recent pd versions. Martin

yep, Thats what i did. it prints nothing for an nrpn and fine for ctrlin and yet i can see the nrpn data fine in midi monitor! baffling

The source code for the ctlin object is in s_midi.c and x_midi.c, all it does is list whatever cc message comes its way. There is no difference between cc98 and cc3 as far as [ctlin] is concerned. No other filtering is done inside pd. If you open the nrpnin abstraction that David attached you'll see that it contains a [ctlin] and is otherwise made of standard pd objects that all work on OSX. I would make a simple patch like this (the first part of the $0-nrpnin-guts subpatch): [ctlin] | | | [pack f f f] | [print] ...and have a look at what it prints.

No the abstraction is fine. Its ctlin thats the problem.. NRPNs are (as far as i understand) just four controller messages in a row. cc99 , cc98, specifying the parameter to affect and cc6 and cc38 specifying the value. looking at plumstone output (a java extension for OS X with a tester app that shows incoming midi) I see this is the case. e.g.
time ch cc data 9567000 [11:4 99 0] 9567000 [11:4 98 4] 9567000 [11:4 6 10] 9567000 [11:4 38 27]
so thats why i dont see why ctlin has a problem with them. If i send a cc99 message to ctlin it has no problem.
Is nrpn just not supported by ctlin on os x?

Checking http://www.borg.com/~jglatt/tech/midispec/nrpn.htm it seems that nrpns _are_ standard cc messages: they're 98 and 99. If your [ctlin] outputs those then the problem is with the nrpn abstraction.

Hi David, The problem is with ctlin. I attached a print to a ctlin. Loads of numbers for standard cc messages. Not a sausage for nrpn! Any other ideas out there? Thanks Nick
