In the end I had a major tidy-up, mostly successful but there are some remaining issues. I decide to uninstall ECO and BFD2, any legacy projects using ECO would only be snippets and ideas anyway. I deleted and reinstalled all the expansions that were in the ECO folder, selecting the BFD3 only options.
I deleted the orchestral and Drum Drops Folk Rock folders and copied back the original uncompressed versions – no distortion is apparent, so the distortion I experienced previously may well have been something to do with BFDLAC conversion. I may run it again at some stage, maybe staying with 24 bit and see what happens.
After moving stuff there seemed to be a few oddities so I did a complete re-scan, which seem to go into a loop on the Groove Monkee groove folders that had previously been in the ECO folder so I dragged them off to a archive, the ones in the BFD2 folder were fine. This needs further investigation to make sure I have everything.
The Nick Mason and Hugh Padgham Kits from Sonic Reality are not showing up in BFD3 after the scan. I seem to recall I had issues when I first installed them but never knew what resolved it. I am downloading fresh versions of the installers and will see if that helps.
And finally (for now) a number of kit pieces seem to have lost their icons and appear in the browser as a “document icon” and in the mixer as a microphone.
