AUXILIARY OUTPUTS
THE FOLLOWING PARAMETERS ARE THE SAME FOR EACH AUXILIARY 1 TO 8
(where x is the auxiliary number)
AUX > x CHANNEL LINK
Connected to Chan > (A to H default: 1 to 8 set to A to H
respectively)
- assigns the auxialiary to which ever PRO-4 channel you wish to set it to, i.e. the auxiliary will respond to
MIDI controllers on the same MIDI channel as the PRO-4 channel it is assigned to.
AUX > x CONTROLLER
(pb, vel, aft, controllers 1-120, default: #16 general purpose
controller)
- sets the MIDI controller source to control the analogue auxiliary output level, to control filter cut-off, VCA
etc.
AUX > x OUTPUT LEVEL For cntrl Min
(-128 to +127, default: 0)
- sets the auxiliary output level for when the MIDI Controller Source is at its minimum.
AUX > x OUTPUT LEVEL For cntrl Max
(-128 to +127, default: 100)
- sets the auxiliary output level for when the MIDI Controller Source is at its maximum.
AUX > x OUTPUT LEVEL Reset Level
(-128 to +127, default: 0)
- sets the level that the auxiliary will reset to when a MIDI reset command is received.
The range of -127 to +127 corresponds to an output voltage of approximately -12.7 Volts to +12.7 Volts.
Most synths, such as Roland, for example, may only need a range of 0 to +10 Volts (0 to 100 on the PRO-
4). Some other synths may need a different range. Korg MS10s and MS20s, for example, use a range of -5
to +5 Volts to control their filter cut-offs, etc. (-50 to +50 on the PRO-4). By setting the Controller Minimum
to a higher number than Controller Maximum, the range can be reversed. Say you want a range of +5
Volts to -5 Volts (as opposed to -5 to +5), set the Max level to -50, and the Min level to +50. This way, when
your controller is at its minimum, the auxiliary output will be +5 Volts, and at -5 V when the controller is at
its maximum. Adjust these settings to what seems to work best with your synth.
AUX > x LFO DEPTH CONTROLLER
(pb, vel, aft, controllers 1-120, default: #1 mod
wheel)
- sets the MIDI controller source to control the LFO depth that will modulate the auxiliary output.
AUX > x LFO DEPTH For cntrl Min
(0 to 127, default: 0)
- set the minimum LFO depth that will modulate the auxiliary output when the MIDI controller is at a
minimum.
AUX > x LFO DEPTH For cntrl Max
(0 to 127, default: 64)
- set the maximum LFO depth that will modulate the auxiliary output when the MIDI controller is at a
maximum.
AUX > x LFO ASSIGN Use LFO number
(1 to 4, default: 1=1, 2=2, 3=3, 4=4. The LFOs
cannot modulate auxiliaries 5 to 8)
- lets you assign which of the four inbuilt LFOs will modulate the auxiliary.
