Bulk Protect - Yamaha P-100 Owner's Manual

Bulk protect

The bulk protect function protects the P-100's internal settings against incoming system exclusive messages.
When this function is turned on, as is normally the case, the P-100 will not accept any incoming bulk dump or param-
eter change messages. When it is set to bulk ("bul"), the P-100 will accept parameter change messages, but protect
against bulk messages. Finally, when turned off, the P-100 will allow its memory to be overwritten by incoming bulk
dumps and system exclusive messages.
