In some applications what would be considered a fairly large organ (e.g., one with say, 200 stops and 60 preset pistons), may also have the desirability for a considerable number of memory levels. The current µMIDI Board (A1-17530) has a limited amount of memory available for a combo action, and thus may allow only a half-dozen levels of memory for an organ of this size.
To obtain more memory, a new board had to be designed using a surface mount processor in order to achieve approximately 20 times the memory capability of the standard µMIDI Board. This translates roughly in allowing around 100 levels of memory for this µMIDI Board (A3-17530).
There is a one to one relationship in the Micro-MIDI Control System for the combination action. That is, a µMIDI Board and a Magnet Driver Board being required for each group of (up to) 48 stops; the hypothetical organ above would require (4) Magnet Driver Boards and (4) of the A3-17530 µMIDI Boards.
While this special µMIDI Board is intended for use in the combo action of any organ where several levels of memory are desired, it is, at the same time, interchangeable with any other µMIDI Board. The only exception is where a µMIDI Board is needed to allow for analog inputs. Analog inputs are excluded from this board.

Here is a normal setup of Micro-Midi Controllers with their power supply. Note the midi cables providing a pathway for the data flow within the system. Each Micro-Midi Controller in this system has a specific purpose for input or output.
