After reception of “speed result 2” SPEED2 is set on both

the master and slave device.

Possible Speed and Max Speed parameters:

SPEED | x 31.25 kbit |

1 | 1 |

2 | 2 |

3 | 3.33 |

4 | 4 |

5 | 5 |

6 | 6.66 |

7 | 8 |

Active sensing:

Active sensing should be sent from any device supporting

Turbo MIDI whenever a higher speed is used

(TM-1 approx 150ms between).

If a Turbo MIDI device receives active sensing and

then active sensing is lost for more than 300ms the device

will revert to normal MIDI speed.

Negotiation Timing:

Length of master timeouts: 30 ms minimum

Length of slave timeouts: 15ms minimum, 25 ms maximum

The timeout is for a byte, not a message, a message could

take 15xN ms to reach the slave.
