Emax

For my project I assume that the Emax indeed has no bulk load/unload 
command. But that's not necessarily a problem because it has a SYSEX 
implementation which covers (almost) all parameters available in a 
bank. So it is possible to use a set of these commands to simulate 
the load/unload of a full bank. The only question will be whether the 
large amount of SYSEX instructions will be acceptable from an end-to-
end response time point of view... That's subject of the experiment :-
)

It's interesting though to think about how the CDS3 cdrom drive 
communicated with the Emax. If the Emax behaves like the Emulator II, 
i.e. if the Emax acts as a slave of the device connected to the 
serial port, then they must have encountered exactly the same 
problem: either the computer in the cdrom drive could send a bulk 
load command to the Emax (which means that the Emax OS is equipped 
with this command), or it had to send individual SYSEX commands.
But if the Emax OS contains logic which can operate the CDROM drive 
as a slave device (the opposite), then the Emax may have instructed 
the CDROM drive in the same way as it did through SCSI.

As far as I know the CDS3 drives had a computer onboard so that they 
could instruct the Emulator II to execute commands. In fact these 
drives can be considered to be "very small computers including a 
cdrom drive" fitted in a handy box with numeric keyboard and running 
a small operating system in order to communicate with the num 
keyboard, the Emulator and the cdrom drive. 
Are these the very same drives that also could be used on the Emax ?
