MIDI hook-up
The MAC 1 accepts program changes from most MIDI foot controllers, from another MIDI controlled unit or
manually by dialling the VALUE WHEEL (F5) in PLAY mode.
An important thing to know about MIDI, is the idea of MIDI Channels. Most MIDI messages are sent over a
MIDI Channel, of which there are 16. In order for one MIDI device to communicate with another, both devices
must be operating on the same MIDI Channel.
The MAC 1 can be set to operate on any one of the 16 MIDI channels (01-16) or in Omni mode (00).
In Omni mode the MAC 1 will respond to MIDI messages on all channels.
To Set The MIDI Channel
After pressing the PR/CH (F6) button the display will indicate the current MIDI Channel setting (00 - 16)
The default MIDI Channel is "01"
Use the VALUE WHEEL (F5) to select channels 1 to 16 or Omni mode.
Press the PR/CH button again to store the channel setting and return to play mode.
Controlling FX mix A and B via MIDI
You can control FX mix A and B via an expression pedal.
After pressing the PR/CH (F6) button choose mixer, either FX mix A or FX mix B.
The display will indicate the current CTL setting (000-127). At setting "000", the mixer can be controlled via
the VALUE WHEEL (F5) on the front panel. Every setting above "000" is controlled via an expression pedal.
Use the VALUE WHEEL (F5) to select the CTL-number to which the unit should respond.
When finished editing, press once again on the chosen mixer button.
Press the PR/CH (F6) button to store the setting and return to PLAY mode.
Note: When programmed for external control via expression pedal, the mixers FX A or FX B cannot be edited
as usual as they are now in "slave-mode"
VCA control
The VCA control allows you to control your master volume with an expression pedal connected to a MIDI
board.
The volume knob on the front panel adjusts the overall volume level from the VCA left and right
outputs. In middle position the signal volume is 1:1.
In maximum position the VCA boosts the signal 3dBu
Two ways to connect the VCA section on the rear panel:
1)
The VCA section is placed between the loop section and the FX mix section.This allows effects con
nected to the FX mix section, ex. delay or reverb, to fade out naturally when the VCA is turned
down.
2)
TheVCA section is placed at the end of the chain, after the loop section and the FX mix section, giving
you an instant master volume on all effects.
