Casio CZ/ VZ/ FZ - Pro Series

dreamend:

For whatever reason, the CZ-101/1000 doesn't spit out the
data in the perfect way so that you can simply reverse the
process. When requested, the CZ gives you the data you
asked for, which is what we went through with the multi-step
process.

To reverse the process, and to put that information BACK on
the CZ, you have to rephrase the header. You have to edit
the header a little bit to politely request the CZ to store
the data.

Every time you ask the CZ for a patch, it gives you some hex
data that starts like this:

F0 44 00 00 70 30 00 00 00 00 00 ... F7

For the purpose of this discussion, let's divide the big
message into a header portion, and the body of the message:

-----Header-------   ------Body------------
[F0 44 00 00 70 30] [00 00 00 00 00 ... F7]

The header portion needs to be edited so that the CZ will
know to store the data in a certain memory location.
With the header as it is, it is saying:
F0 "hello"
44 00 00 "Casio machine"
70 "using channel 1"
30 "okay"

You want to edit it to say something like:
F0 "hello"
44 00 00 "Casio machine"
70 "using channel 1"
20 "store a patch"
20 "In INTERNAL memory 1"

So the stored data you have looks like this at the beginning:
F0 44 00 00 70 30

You need to change it to say:
F0 44 00 00 70 20 20

Notice that YOU HAVE TO ADD A BYTE, a byte which says which
memory location to store it in. Without this, nothing will
happen. You can add this byte using a hex editor, but it's
much easier to do it with MIDIOX, right when the patch is
being saved.

You have to change the seventh byte so that each patch is
stored in a different location, like this:

F0 44 00 00 70 20 20 - store a patch in INTERNAL 1
F0 44 00 00 70 20 21 - store a patch in INTERNAL 2
F0 44 00 00 70 20 22 - store a patch in INTERNAL 3
F0 44 00 00 70 20 23 - store a patch in INTERNAL 4
...
...
F0 44 00 00 70 20 2F - store a patch in INTERNAL 16

I wish this was easier to do, but that's what you get
with old keyboards. Lucky it has sysex at all. The Casio
CZ-1 just gives out the data in ready-to-go format.

TO SUMMARIZE:
In the header of the sysex data you stored, change the
30 to a 20, and then add a byte right after the 20
that says what memory bank to store it in.

Let me know how it goes.
