(2) PROGRAM DATA DUMP REQUEST R
+----------------+--------------------------------------------------------+
| Byte | Description |
+----------------+--------------------------------------------------------+
| F0,42,3g,46 | EXCLUSIVE HEADER |
| 0001 1100 (1C) | PROGRAM DATA DUMP REQUEST 1CH |
| 00uu 000b (ub) | Unit(00:Prog/01:Bank/10:All),Bank(0:A/1:B) |
| 0ppp pppp (pp) | Prog No.(Ignored when Bank or All dump.) |
| 0000 0000 (00) | |
| 1111 0111 (F7) | EOX |
+----------------+--------------------------------------------------------+

The above table really confuses me. I hope there is someone who can help with explaining what is going on. I'd like to request a complete bank of sounds from the Z1 without having to do a manual dump but just can't work out how to do it.

So far I have successfully downloaded Bank B by using the sysex message:

F0 42 30 46 1C 11 00 00 F7 (84,270 bytes) Bank B
^^^^^^^^ Exclusive Header
^^ Program Dump request
^^ Unit(00:Prog/01:Bank/10:All),Bank(0:A/1:B)
^^ Prog No
^^ 00
^^ EOX

But when I try to download Bank A with a sysex message of:

F0 42 30 46 1C 10 00 00 F7

it appears to return both Bank A and Bank B, so there is twice the amount of bytes sent. Can anyone throw any light on this sysex conundrum?

Hi,

Looks ok what you are trying to do...

Hence, must be some documentation/implementation issue at Korgs side?
The byte 10 looks similar as the binary 10 (dump ALL) unit field. Maybe that was coded wrongly in the board?

Bye

Thanks for your reply OpAmp and I think you're right and the problem is with Korg's midi implementation. I have an old software editor from 1999 for the Z1 called "Zed" created by nooloop. It's abandonware now and has a few flaws but it has some very powerful features so it was worth looking at the messages it sends when requesting Bank A. The message was identical to the one I was sending to the Z1 and "Zed" returned both Bank A and B like I witnessed.

So it seems the fault lies with the Z1 itself. SoundDiver instead uses single requests for each program so uses a different system for retrieving bank sysex.
