6.13.4 MIDI Control 

Figure 6-31 MIDI SETUP

The MIDI setup window allows you to control fader 

values, channel mutes, and snapshots to be modified re-

motely from a sequencer or other MIDI-equipped device 

connected to the TT24’s MIDI IN connector. Addition-

ally, the TT24 can be configured to send MIDI messages 

from its MIDI OUT connector when these parameters 

are changed from the console surface.

Enabling MIDI Input and Output

MIDI messaging in the TT24 is disabled by default. To 

configure the TT24 to respond to supported incoming 

MIDI messages, click or press the RECEIVE button in 

the MIDI page to highlight it. Similarly, to configure the 

TT24 to send MIDI messages when supported param-

eters are changed, click or press the SEND button in the 

MIDI page to highlight it.

Configuring the MIDI channel

MIDI messages are transmitted and received using 

one of sixteen MIDI channels. In order for the TT24 to 

communicate with another device, both pieces of equip-

ment must be configured to use the same MIDI chan-

nel. To set the TT24’s MIDI channel, click or press the 

number of the desired MIDI channel in the MIDI page 

of the SETUP menu to highlight it. The selected chan-

nel will be used by the TT24 when sending or receiving 

supported MIDI messages.

Note: MIDI message bytes are represented using 

hexadecimal notation. See the table on the next page 

for decimal to hexadecimal conversion.
