Mute Automation

MIDI

When you want to use an external MIDI sequencer to provide mute automation,
instead of the X2's internal sequencer, you must select a MIDI channel and choose a
MIDI Map. There are several different sequencers to choose from, although we
recommend using a sequencer that provides "event chasing," so that you can locate
to any location on your sequencer and be confident that it will update the mixer
with its correct mute status for that particular section of the song.

MIDI Channel

The MIDI Channel value determines which MIDI channel the X2 will transmit and
receive mute events on as MIDI messages for recording and playing back on an
external MIDI sequencer. The messages that are sent representing the mute events
are determined by the currently selected MIDI Map (see next section). You can
transmit and receive on any one channel, from 1 to 16, or you can choose all 16
channels simultaneously; this is called omni mode. Use omni mode only when you
are using the MIDI sequencer exclusively for recording and playing back mute
events.
J
The MIDI Channel and Map displays are disabled if the Sync Source is set to "Ad" (ADAT
sync).
To set the MIDI channel:
1 Press the DISPLAY button until the CHANNEL LED is lit.
2 Use INC/DEC to change the value.
Choose 01—16 for MIDI channel 1 through 16, or 00 for omni mode (all 16).
It is recommended that you use a MIDI channel that is not being used by another
device (synth, sampler, drum machine) connected to the same source as the X2.

Selecting Songs via MIDI

Using MIDI program change messages, you can select any of the 100 Songs. These
messages can be sent by a MIDI sequencer or some type of MIDI controller
(particularly useful in live performance applications). The X2 responds to MIDI
program change numbers 000—099 to recall Songs 00—99, respectively. This means
every time you send a program change message, you can call up four entirely
different Mute Groups, thus giving you instant remote access to all 400 Mute
Groups.
Once you have selected a Song using program change messages. you can select any
mute on the console or Mute Group by sending the appropriate MIDI message. The
type of MIDI message that each Mute and Mute Group responds to depends on the
currently selected MIDI Map.
