B-CONTROL 

AUDIO

  BCA2000

6.4 MIDI connectors

The MIDI connectors on the rear panel feature the internationally

standard 5-pin DIN connectors. To connect the B-CONTROL to

other MIDI devices, you need a MIDI cable. In general, commercially

available cables can and should be used. Their length should not

exceed 5 m (15 ft.).

MIDI IN:

 This connector is used for receiving MIDI data.

MIDI OUT A/B:

 Data for controlling other MIDI equipment can

be sent through the MIDI outputs.

MIDI THRU:

 MIDI OUT B can be configured as MIDI THRU in the

control  panel  software,  allowing  any  data  received  via  the

MIDI IN to be passed on without being modified.
