Hey hey,
this is not related to any of the MIDI input opcodes. The simplest way to 
provoke this is to have a valid CSD skeleton and in the options section 
something like:
-o dac -d --messagelevel=2 -Ma

Then I move an NRPN knob on a connected MIDI keyboard and see this:
unknown drum param nos, msb 0 lsb some_value

some_value depends on the actual knob tht is moved.

Does anyone know why this happens and if something should be done about it 
inside an orchestra?

Best wishes and TIA,

Jeanette

I'm not totally certain I understand the context. I ran into it before
when I tried to patch csound to make it easier to use nrpn, and I
wasn't a very good programmer then, and haven't been back to look at
it closely since then.

If it's a warning about ability to parse a specific usage of NRPN,
then I think it should somehow be opt in, eg. you could move the
validation and warning into an optional opcode aside from the main
MIDI stream code. People who would appreciate this warning could use
it, and other uses of NRPN wouldn't have the distraction(?).

That said it's just a warning message, it led me on a wild goose chase
at least once but doesn't hurt per se. And there might well be more
going on than I've understood.

If I understand correctly, from the snippet you posted, John, I think
the warning could be removed. I encountered this warning a lot using my
MIDI keyboard which almost exclusively sends NRPNs from 0 to more than
100, maybe 200.

Best wishes and thanks,

Jeanette

I used NRPN to upgrade physical sliders from 128 value precision to
16384 value precision.

It worked great, except for the messages which were not meaningful and
ultimately caused me to waste my time tracking down the cause (I
thought it was a problem with my own code, as I'm sure has happened to
others).

...
I have written a UDO that parses MIDI to generate RPN and NRPN messages.
I use a format similar to midiin, on which this UDO relies. I only
extended the kstatus output to include 16 and 32 for RPN and NRPN.
Though an opcode from within Csound might be helpful. Seeing that it is,
apparently, allowed to only send half NRPN messages when the controller
number doesn't change. The Yoshimi author mentioned something to that
effect, since Yoshimi itself uses NRPNs to give access to many
configuration option and many other parts of the synthesis engines.

Best wishes,

Jeanette

>From what I understood, a few things can happen. IIRC one of them is tht
if you use the NRPN controller, a device may only send the control
number once and then only send the changing values. Or maybe there was
something with only sending the control number lsb. I could understand
both abbreviations, since a full NRPN message takes four MIDI CC
messages. My external hardware doesn't do it, but only one of the family
does send NRPN.

Do you mean that your Axiom doesn't send CCs 98 and 99 at all? These are
the CCs to compose the NRPN controller number, whereas CC6 and CC38 make
up a full value. With those the resolution is complete, 14BIT.

Why? Once a value is set up - don't know how - a usual knob movement
will normally step through single values. Yes, there is a tendency to
have acceleration features on knobs, the faster you turn them, the more
they "jump" through steps. Granted that could ben an issue.

I wonder: I though that Yamaha was the only company really using RPN
parameters. Though that might only hold for their XG keyboards or
instruments in XG mode.

Does anyone here have a Yamaha synth to test? Maybe an old CS2X, CS6X,
maybe even early Motif or one of the bigger digital pianos or arranger
keyboards, the high PSR or Tyros models? It would be interesting to know
what the practise is there, if only to update something like my MIDI in
opcode or a similar module.
