Thanks for the suggestions so far.
I think what I may be doing along the lines of what gumtown is suggesting.
I'm gonna try 3 patches.
1 for the 6th string only
1 for the 5th string only
1 to enable strings 6,5,4, and 3
I'll have a patch that only has the 6 string enabled by default, however i'll have a controller that will allow me to turn on the 5th string where necessary.
I know this may seem a bit laborious, but i'll say this much...the GP-10 is wayyy better than that drop octave bass pickup thing. (not naming names here, but you know of which one I speak) I'm telling u now the GP-10 trumps everything and I mean every pedal and software solution that I have tried up to now. I would've saved sooo much money had i gone to this from the beginning....sigh... live and learn.
