[A6] converting NRPN's to CC's in logic

[Chris Pickett]

Hi guys,

I have put up a screenshot showing how to set up MIDI-OX and MIDI Yoke 
(these are two separate programs).

http://www.sable.mcgill.ca/~cpicke/audio/dual-midi-ox.png

When I turn the ENV 3 attack knob on my front panel (NRPN controller 
#2945), it gets sent through the output port 6 of my MIDI interface into 
the first instance of MIDI-OX, on the left.  It converts the NRPN data 
into CC data perfectly (no skipped values, every number between 0 and 
127 is hit).  I have it set to output MIDI on the "virtual" MIDI Yoke 
port number 6.

Then, the second instance of MIDI-OX on the right is set to receive data 
from the virtual MIDI Yoke port #6, and it maps CC #95 (arbitrary) to 
NRPN 2945.  Then it outputs the data to the input port 6 of my MIDI 
interface.

When I turn the knob on my sequencer, with the panel transmit set to 
MIDI only (no local control), it actually changes values in my A6 display.

Unfortunately ... I am having a hell of a time getting this to work in 
Logic.  In fact, things will be working fine, and then suddenly ... 
*poof* ... Logic is gone.  I think I'll have to try SX out again.

One complication that I did not mention here is that you probably need 
to set the sequencer to receive on one MIDI Yoke port and send on 
another ... and make the same settings in MIDI-OX ... otherwise you 
might get direct communication between the two instances of MIDI-OX -- 
unless of course you want this, and the sequencer exists just as a 
"branch" for recording MIDI.  It's important to avoid MIDI feedback 
loops on your computer.

You need to:

1) Download MIDI-OX 7.0
2) Install the MIDI Yoke driver for Windows 9x and NT/2K/XP, available 
from the MIDI-OX website.

The documentation for both of the above is excellent.  Apparently MIDI 
Yoke does not work with Gigastudio, and the FAQ mentions another 
freeware utility that does the same thing.

Hope this helps -- read the docs for both products if you get stuck.  
Interestingly, if you need a Windows Help to HTML converter, chm2web is 
free for 15 days and works fine (nice because you can increase the font 
size in your browser).

Let me know if anybody gets this working *stably* :) :)

Cheers,
Chris

P.S.  To configure the ports in MIDI-OX, look at the MIDI devices entry 
in the options menu. 

P.P.S.  MIDI-OX is *really* nice in that it remembers different window 
layouts for the first and second instance of the program, even after 
you've closed it!  Neat!
