I thought the Editor and hardware were independent in that you could make changes in the Editor and then had to manually write those changes to the hardware -- the Editor and hardware are not "auto-synced" together.
However, when I Import a PCG into the Editor, the PCG settings are immediately sent to the hardware automatically.

I expected the PCG to just load into the Editor only; allow me inspect the programs/combis in there (and be selective and make changes if I want); and then I manually send over the Editor's copy of the current PCG settings (which would then be a program/combi load in the Editor and not a PCG as such) to the M3.
Instead, I can never use the M3 Editor to pre-inspect a PCG before loading it into the hardware -- which is really what I want to do. I have to have it load (and potentially overwrite) the hardware.

Am I just missing a "auto sync to hardware" option somewhere? I want to turn it off. Thanks for any assistance!
