Hi Bruce,
Yes, what you describe is the normal behavior (just like on previous models).
The parameters you mentioned are, as I said, the System Effect RETURN levels of the System Effects
Reverb and
Chorus. Normally these parameters are left at the default value (here 64). The desired effect proportion in each Style file / MIDI file set separately for each Part (MIDI channel) via the Effect SEND controller ("CC" means "Control Change"):
CC #91 = Reverb Send level
CC #93 = Chorus Send level
CC #94 = Variation Send level
Some users adapt the System Effect RETURN levels to the respective
room acoustics for live performances (especially for the System REVERB effect). To do this, the checkboxes for "Reverb Return Level" and, if desired, "Chorus Return Level" and "Variation Effect (System) Return Level" must be set in "Parameter Lock". The values set in the Mixer (e.g. Reverb Return Level lowered from 64 to 50) are then retained
until the keyboard is restarted.You CAN do what is described, but I have never used this option ...
If necessary, I always adjust the effect settings using the aforementioned Effect SEND controller, i.e. per Part, and then save this in Registrations or directly in the respective Style / MIDI file.
Best regards,
Chris
