Just to clarify some things regarding the Yamaha Fb 01 (synthesizer)
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
