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 |
8 | 10 |
(9) | 13.3 |
(10) | 16 |
(11) | 20 |

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.
