LexiconPCM 90 MIDI Implementation Details
0x01 Bank Dump
This is a bidirectional dump of an entire bank of effects. It is initiated from the front panel as a Bank Dump.

Note that it is possible for a bank to be sparsely populated (for example when a user has only a small
number of effects saved in bank 4 or 5). It is important to check the validity bit in the Flags byte for each
effect. (See Single Effect Data for a description of the validity bit.)
Note that after a bank is received, a period of approximately 2 seconds is required for the PCM 90 to sort
and merge the banks.
Note also that for any effect to be successfully transmitted or received by the PCM 90, the supporting
algorithm must be present (not necessarily running) in the unit. Internal algorithms are always present,
whereas Card algorithms are only present if the card has been loaded. If an effects packet is transmitted
without the algorithm present, an error message is displayed. Such cases also cause special formatting
of the effects packet. See Single Effect Data for details. If an effects packet is received without the
algorithm present, an error message is displayed and the destination remains unchanged.
