I have downloaded from the files area the preset for the D-550 and it sends properly the parameter-values to my Roland D-50. Thanks so much. That's the good news.
The "bad" news is that the original PG-1000 programmer has a parameter request button, so it can read the 224 parameter-values of each four-part patch, before user starts editing an existed patch.
Is anyone aware if BCR-2000 could read the values of a patch, even with a dump from the D-50 ?
Thank you
