Clock messages

[igbro]

Hi Michael,

It would be really useful to have access to Midi Clock messages:

clock (decimal 248, hex 0xF8)
start (decimal 250, hex 0xFA)
continue (decimal 251, hex 0xFB)
stop (decimal 252, hex 0xFC)

And SPP chunk starting with (decimal 242, hex 0xF2)

Thanks for your concern.

Igor.
