Hi brucerez,
I very rarely use more than one Effect block / DSP per part. As far as I know, (unfortunately) the changed parameters are only actually saved in registrations
for the effect block assigned last. However, for the other previously assigned Effect blocks, changed settings revert to their
default values.In principle, however, when assigning several Effect blocks per part, they should all be/remain
active after memorizing in a registration.
It may help if you create User Effect types beforehand and then integrate them into registrations. Unfortunately I don't have the time to test this at the moment.
P.S.
To contact Yamaha, I recommend going to >>>

Best regards,
