Does the Low Bass Tuning Fix actually work, or what am I doing wrong? I've repaired the file and clicked the Fix Low Bass Tuning and hit save on a couple of files. None of them work any better after. Specifically, I've tried Poem by Taproot multiple different ways, still doesn't read the low A on my 5 string.

CFSM 'Repairs' option does not currently apply/support the low bass tuning fix to CDLC (I will add this as an option in future revision).  Currently you can use CFSM 'Custom Mods' 'Pitch Shift' which will apply the low bass tuning fix if necessary but this option will also pitch shift the CDLC arrangements to e-standard or drop-d which may not be what you want.

 

If you want to retain the original tuning then you should use the toolkit to apply a non-modded low bass tuning fix.  You can use either the toolkit's 'CDLC Creator' to 'Import Package' and then 'Generate'.  Alternatively you can use the toolkit's 'Packer/Unpacker'  to unpack and re-pack the CDLC both of which will fix the low bass tuning issue if it is present in a CDLC. 

 

If you use the toolkit, then make sure you have checked the box 'Fix Low Bass Tuning' in the 'General Config' menu settings first before using either of the above toolkit repair methods.

CFSM now supports low bass tuning fix.  See the 'Repairs' tab.
