INTERNAL MIDI CLOCK/CHANNEL NUMBER
From Version 2 firmware, the Xone:DB4 has the ability to
generate internal MIDI clocks which can be used to control the
tempo of a connected DAW via USB.
To activate internal MIDI clocks, press the MENU button and using
the SEL/ADJ encoder, scroll down the list to MIDI SETUP - press
the encoder to enter the MIDI SETUP menu.
Clock BPM: The current clock tempo is displayed in BPM to the
nearest decimal point. To change the tempo, select the item and
press the encoder once and rotate.
Enable: To activate MIDI clock, scroll to Enable and press the
encoder to turn On.
If the BPM RANGE (see page 24) is set to “MIDI Clock” and the
Internal MIDI clock enabled, global tempo for the effects and
loopers is set by the internal MIDI clock.
Channel: The DB4 defaults to MIDI channel 16, to change this
scroll to Channel, press encoder and rotate, then press again to
store the new value.
