The two suggestions discussed in the linked thread: A) Multiply the !BPM to create the on/off, this does not work as my clock signal is constant regardless of stop/start state. and B) Using OSC to piggy back messages is not ideal right now.
Q: Is there an object where I can capture specific MIDI bytes and translate them into !Messages?
Q: Could the Start and Stop messages be integrated into the Global Map?
