Title: RPNs?
Post by William on May 19^th, 2003, 6:03pm

Hi there ... I've been searching (rather desperately, actually) for a program that essentially does what this one does. However, I need to change the pitch bend sensitivity (RPN 0) according to the intercept of another controller (e.g., Expression) because the program I'm using to write music doesn't support RPNs. I can't see anywhere in Midi-Ox where I can map to an RPN - only to NRPNs. Does Midi-Ox support RPNs and, if not, is there a Sysx message or something I could use to achieve the same result?
Thanx, muchly!

As I reply to myself ... hmmm ....
Anyway, I found ***Pitch Bend in the MIDI Send Controllers thingie and that's kinda resolved the problem and introduced a new question. The pitch bend range should be 0-16383, yet MIDIOX only allows a single value up to 127. It doesn't quite do a x128 on the input value because I had to adjust all my pitch bends to a greater extreme in order to get the correct tones again. It'd be nice if you could automate sending controller messages - especially RPNs.
Me to Myself.

RPN Mapping will be in the next release.

Do you mean the MIDI Status View or are you referring to the Control Panel? They both contain methods to send Bend Range RPNs.

With both NRPN's and RPN's it's common to only send the Data Entry MSB when the resulting resolution is sufficient. This is the case with Pitch Bend Range: the Data Entry MSB represents the number of semi-tones of Bend to perform in either direction (2 is the default for most Synths). The 7 bit Data Entry LSB can theoretically be used to carve the Bend range up even finer, but I've never seen it used, and that's not supported by MIDI-OX.

I was referring to the Control Panel ... sorry 'bout that. I never tried the Status View until you mentioned that you could do something with it. "Status" View made me think it was a "read only" type of view.

Yes, I can appreciate that. It was just a nuisance having to go through all the pitch bends to get the tones right again. Anway, thanx for the great program (though, it's so featured that there's a bit of a curve!)
