You weren't kidding!
I have Chameleon and the "old" Alchemy, both installed in default locations, but I have no "Legacy" content in the new Alchemy.This should work. There is a legacy Content category in the Alchemy sound library. If you have your alchemy library installed correctly, the presets should be listed there.
There is no other software that has been my companion for so long in my musical life, thank you Gerhard Lengeling and the Apple Team, clearly again a model of excellence in the DAW market, may apple follow the same track for their other products !
I just checked and iBooks gave me updates for the Logic Pro X User Guide, Instruments and also Effects. Alchemy is included.The Logic manual in iBooks is still the one issued last January. Has anyone seen an updated manual that covers the additional features?
