Custom PCB / Veroboard Info
This is the mapping for the MBQG_FP board itself–if you have the commercially produced PCB from
Sauraen, you don't need this info because it's already in the copper!
MIDIbox Quad Genesis supports its front panel controls in any valid MIDIbox button-LED matrix
configuration, with the following restrictions:
DOUT Restrictions
The same BLM must be used for buttons and LEDs, and it must have 8 rows.
LED display digits must be common anode, connected with their anode to a DOUT shift register
pin, and their cathodes to the row lines in the order 0-7 = A-B-C-D-E-F-G-DP.
DIN Restrictions
The same BLM must be used for buttons and LEDs, and it must have 8 rows.
Encoders must have their common pin grounded, and their two switching pins directly
