[linux-audio-user] midi filter to convert NRPN's to CC's

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



	The problem will actually be getting the NRPN's into PD. There
are built in pd objects for [ctlin] which gives you 3 outlets, one for
the Value, one for CC# and one for channel. There is a [midiin] object
that might give you raw Midi info that you can parse, but like I said in
my first email, I have never really used NRPN's so I don't know how you
would go about getting them into PD.

You could search the PD list archives here:

http://iem.at/mailinglists/pd-list/

Or just join the list its self. It is full of a bunch of very helpful
folks (many of whom are also here).

David Mccallum has done a couple of abstractions dealing with NRPN's
including it appears [nrpnin] and [nrpnout]. So this would be a good
place to start.
