Hi everyone.
Just to clarify some things regarding the Yamaha Fb 01 (synthesizer)
sysex flow
I'll give an example and I attach a relevant page of the manual
in order to change the output level (value pp) on channel 1
i'm using the message

F7 43 75 00 10 24 pp F7

Please let me know if i'm correct?
I wonder why it doesn't work. Of course i may have made a connection mistake.

Thanks in advance

Wouldn't it be easier to change the channel volume using regular MIDI messages: B0 07 xx, B0 27 xx ?

Thanks for the reply. Yes it would be.
But that’s not the point.
I used the volume parameter as an example of a parameter with variable values.
If i’m correct to my sysex message it means i can use my translation to other parameters as well.
If i ‘m not i need to,kniwvwhat can be corrected.

Thanks a lot.Absolutely right.
But i think this is a typo. What about the rest of the message?

ps. Yes my message is correct. It needed a bit of correct port set up and all good.
Thanks everyone
