Sysex problem with Roland Gaia

[theKI]

Hello everybody!

I am trying to send some SysEx to my Roland Gaia SH-01.
What I'm trying to do is to change the channel of the Rx/Tx Channel (the sending en receiving midi channel) over SysEx.
I have followed the Roland Gaia's manual to try to make my SysEx message, but I can't get it to work...

In the example underneath I try to set my midi channel to Ch.8

My message:
F0 ==> Start sysex

41 ==> Roland ID

10 ==> Device ID

00 ==> Model ID
00
41

12 ==> Bit to tell the Gaia I'm sending data, and don't want to receive data.

01 ==> The adres of the Rx/Tx-channel
00
00
11

00 ==> Value I want the Rx/Tx Channel to be set to
00
00
07

67 ==> Roland Check Sum

F7 ==> End of SysEx.
__

I can't seem to find where the problem is... I think it is somewhere in the adres or the value part, but I'm not 100% sure.
If I send this SysEx, the Gaia doesn't change it's value...

I hope there is someone who can help me!
If you need some extra information, let me know.

Anyway, thanks in advance everybody! ;-)
Keanu
