Seems related to having modified a MIDI file for a .sng crafted from REAPER then used the BB Mgr (126.96.36.199) edit function (simply reassigning channels to correct misaligned drum parts and adding a few beats) with a standard unmodified drum kit (StandardPBass). All is functional and plays on the Manager.
Attempting to synchronize for pedal use I get an ‘Unable to copy…Drumsets/8E08AD5D.DRM to…’ Retry attempts on both cards went forward following some random (and likely unrelated) actions on my part - rebooting Mgr, opening the folder and clicking on the specified offending DRM file.
Using the SD card now the drumkit is corrupt - sounds mis-assigned all over but still plays fine in Mgr.
DRM in question deleted via Mgr from the project but still shows in the folder labeled as ‘modified’. Reloading the DRM and attempting synchronization shows ‘Unable to delete/Volumes/Drumsets/ config.csv’
Rebooted everything and got the same error as earlier ‘Unable to copy same drumset…’
Currently Mgr plays everything fine but the .sngs on my pedal for any using this kit are corrupt.
