Title: Hardware-Merger for NRPNs
Post by Martin.H on Jan 11th, 2006, 1:17pm
Hello!
I'm working at a project, where I need to use a merger (8x8) like the Midisport (M-Audio) or the Unitor (Emagic / Apple) in stand-alone-mode.
Some of my units send NRPN-commands that should get mixed. Because each NRPN uses 3/4 Midi-control-messages, I guess that not any merger can handle them correct and could fragment them.

Is there anyone who has some experiences or knowlegdes about this problem? - Do you know a merger that works?

Thanks a lot! - Regards
Martin Holzhauer

It shouldn't really matter because there is no rule that says all 3 - 4 or even any 2 NRPN messages must be consecutive.  As long as they are all arriving within a reasonable time (and even if not) your gear should work correctly.  

The only conflict I can imagine is if two pices of gear send NRPNs simultaneously, but no merger would sort out that situation.

That's the point I'm thinking about! - I must expect this case because there are minimum 3 devices sending NRPNs.
In theory it should be possible for the merger to reserve the output after sending a NRPN-relating controler for a short time something like 1ms (round about one Midi-Message) for the last source. - But do they?

Is there anyone who has an idea for this?
Thank you, regards
Martin
