I hook myself to this old thread and ask forgiveness in advance for the somewhat articulate and probably unusual request and for my poor English ...
In the iMac in signature (late 2009) I have a stable configuration with El Capitan which allows me to install up to Logic 10.3.3, of course. On an external HD I installed Sierra and Logic 10.4.1 to try if there are problems and, unfortunately, it is not so good. In Drum Kit Designer in Logic 10.4.1 there are new interesting drum kits. I tried to copy both the new Sampler instruments (HD> Library> Logic> Sampler Instruments> Drums and Percussion> Drum Kit Designer ...) and the missing samplers (HD> Library> Application Support> Logic> EXS Factory Samples> Drum Kit Designer Consolidated) from HD with Sierra to the one with El Capitan, in the hope of being able to use them with Logic 10.3.3. Unfortunately 10.3.3 sees the new kits (for example Speakeasy) but does not find some samples and asks me for the download, but being on 10.3.3 is not possible. Am I doing something wrong or do you think there is any incompatibility between the kits of 10.4 and 10.3?
Thanks...
