The midi data area starts at address 4D2h in the GFX-1. The Request Ram Area
and Receive Ram Area procedures may be used to update this area without
causing the GFX-1 to reset. (Ram Address = 4D2h + ram byte number - 1)
Data format for the GFX-1 Receive One Program procedure
Please note that each internal ram byte (d7 - d0) is transmitted as 2 midi
bytes. The first midi byte is 0000000xb where x is d7. The second midi byte
is 0xxxxxxxb where x is d6 - d0. Refer to the Receive One Program procedure
in the General Midi Implementation Manual for required header information.
