[sdiy] Midi2cv Project Update

[phillip m gallo]

Tim,

"Running Status" does not neccesarily have to be implemented.  My Roland
A-33 kybd does not default to running status. My "Miracle" keyboard does.
My sequencers vary all over the map.

It's pretty easy to implement Running Status in code if you retain a
"context" status variable which contains the last command issued. This
variable is "re-written" when a new command (on your channel) occurs (which
isn't active sensing).

regards,
p

The $FE bytes are active sensing bytes and can actually occur
*between* the bytes of longer messages.  Some keyboards allow
turning active sensing off, but that would take all the fun
out of writing the code!
