Revised PreenFM2 MIDI page
« on: July 26, 2017, 03:09:00 PM »
From the HTML it looks like this page is generated dynamically.  But I have edited it to include everything I have determined about the actual ranges and values of the various NRPN inputs.  I hope this is helpful.

I'll make a diff and update the page.

I've found a problem with the Preen's NRPN dumps violating its ranges.

Bank 3, Patch 2 ("Resolead  MB").  When loaded, OM Index 1 is 18.0 and Index 2 is 25.0.  This sends NRPN values of 1800 and 2500 respectively, outside the 0...1600 range specified.  This causes two problems:

1. You can't use the knobs on the machine to go to 18 or 25.  So you can *load* this patch but you cannot *create* it (!?)

2. It's not clear what the upper limit is over NRPN.  What should a patch editor do?  Should I bound it to 0...1600?  Then if I send it back, it's a different sound.

NRPN has no limit, but crash free is not guarantee.
The preenfm2 UI has a limit.
As simple as that ;)
