I did a little testing with 1.8 as well.  This is my first use of FactorLib so sorry if my questions are not 1.8 specific. 

when I try to load more than 1 preset from FactorLib to the pedal at a time, the display on the pedal says "BAD", then nothing else happens.

When I load the presets one at a time, the pedal says "upload ok",  the settings seem to be good, but then I need to save the patch name on the pedal manually, it doesn't keep the patch name from the FactorLib file.  does that sound right?

Also, what's the best way to re-arrange presets?  In FactorLib it's easy, drag and drop.  But since I can't do multiple uploads to the pedal at the same time, that makes it hard to move around presets without erasing other ones.  Example, keep it simple, i'm using banks 1 and 2.  I want to put 1-1 into 2-1, and 1-2 into 2-2.  Would be nice to be able to do that in FactorLib and do a dump to the pedal from the Computer and have patch names and parameters all adjusted.

If I'm missing a feature in FactorLib, please let me know,

thanks,
