Title: converting NRPNs on korg electribe em-1
Post by kmkrebs on Dec 19^th, 2002, 5:39pm

I'm trying to use midi-ox & midi-yoke to allow me to use my Electribe EM-1 as a midi controller for software. However, all the knobs use NRPNs.
I managed to get a map file for midi-ox from the electribe user group on yahoogroups, except it is made for the ES-1, which differs slightly in the number of knobs (two less).
This map works to some degree, although it seems to group several knobs together, and after using more than one knob, there is no longer any differentiation between them.
So, I'm attempting to map myself up a revised map file that will work correctly, using the older one as a template. I've check in midi-ox to get the information about the NRPNs for the EM-1, but I cannot wrap my head around how the conversion takes place with the map file.
Could someone point me to a reference on exactly how I go about making the map file to convert the NRPNs? Please be warned, while I understand how MIDI works, I don't understand many of the intricacies.
Thanks in advance! :)

There's go info about NRPN's in general here: NRPN (http://www.borg.com/~jglatt/tutr/rpn.htm)

In gerneral, NRPNs are implemented by specialized CCs: up to 4 different CCs are required to fully specify a NRPN. When you convert a CC to a NRPN, you'll see that the single CC is changed into 3 or 4 CC's comprising the NRPN. However, the map itself only uses a single line to specify the conversion.
