28.5 MIDI Control
The hardware output which is set up as
Main Out can be controlled by the standard Control
Change Volume via MIDI channel 1 . With this, the main volume of the Fireface is controllable
from nearly any MIDI equipped hardware device.
Even if you don't want to control all faders and pans, some buttons are highly desired to be
available in 'hardware'. These are mainly the
Talkback and the Dim button, and the monitoring
options (listen to Phones submixes). Fortunately a Mackie Control compatible controller is not
required to control these buttons, as they are steered by simple Note On/Off commands on MIDI
channel 1.
The notes are (hex / decimal / keys):
Dim : 5D / 93 / A 6
Mono : 2A / 42 / #F 2
Talkback : 5E / 94 / #A 6
Recall : 5F / 95 / B 6
Speaker B : 32 / 50 / D3
Cue Main Out : 3E / 62 / D 4
Cue Phones 1 : 3F / 63 / #D 4
Cue Phones 2 : 40 / 64 / E 4
Cue Phones 3 : 41 / 65 / F 4
Cue Phones 4 : 42 / 66 / #F 4
Snapshot 1 : 36 / 54 / #F 3
Snapshot 2 : 37 / 55 / G 3
Snapshot 3 : 38 / 56 / #G 3
Snapshot 4 : 39 / 57 / A 3
Snapshot 5 : 3A / 58 / #A 3
Snapshot 6 : 3B / 59 / B 3
Snapshot 7 : 3C / 60 / C 4
Snapshot 8 : 3D / 61 / # C 4
Trim Gains : 2D / 45 / A 2
Master Mute : 2C / 44 / #G 2
Master Solo : 2B / 43 / G 2
Note: The hex va
lue is standardized, the key is not. If it doesn’t work try all notes one octave
lower.
Furthermore all faders of all three rows can be controlled via simple
Control Change com-
mands. The format for the Control Change commands is:
Bx yy zz
x = MIDI channel
yy = control number
zz = value
The first row in TotalMix is addressed by MIDI channels 1 up to 4, the middle row by channels 5
up to 8 and the bottom row by channels 9 up to 12.
16 Controller numbers are used: 102 up to 117 (= hex 66 to 75). With these 16 Controllers (=
faders) and 4 MIDI channels each per row, up to 64 faders can be controlled per row (as re-
quired by the HDSPe MADI).
