Bc2000 (for the BCF2000 & BCR2000)

hope I dont double post here .. network dropped during first post!

Midi clock (0xF8) is sent 24 times per quarter note.
Recall BPM is the number if 1/4 notes per minute.
So at 100bpm you should see 2400 F8's.
NOTE: only my keyboards that have inbuild MIDI sequencer send this.
First time I encountered it I freaked ... then internet explained I just need to "deal" with it.
It can, and should be expected to, appear in the middle of messages.

The active sense seems to have gone out of favour.
But it is the heartbeat, as Mark suggests.

According to "MIDI for the Professionals",  by Paul Lehrman (page 28) .. active sense should occur at less than 300 ms intervals.
When a receive doesnt hear these, but was expecting one, it sends "all notes off" message. Some devices also send 0xFF to master reset.

At "Tempo 240" its around 100 signals/sec. (still F8 and FE signals interleaved but in the latter case much more F8 signals)
