When initially powered, after a short start up animation, MFX displays the active
effects program. Other available programs can be browsed by twisting the program
knob and made active by clicking the program knob. Once a program is made
active, its last edited parameter screen is displayed. Parameters can be cycled
through by turning the program knob. Clicking the knob will highlight the selected
parameter and turning will then set its value from a range of available values (and
cv assigns - see next para). Clicking again will exit. To return to the program
selection, press the back button.
Audio signals are patched in to either the left input (mono source) or both left
and right inputs (stereo source). The audio signals are then processed by the
selected effect program and sent to the stereo audio outputs. The red LEDs indicate
when audio signals are too high and are causing clipping at the inputs - if this
occurs, care should be taken to lower signal volumes into the MFX.
Assigning CV Control
On a parameter screen, scrolling left past the lowest value of a parameter will
select one of the assignable CV inputs to externally control that parameter.
Alternatively, when a parameter is highlighted, holding the back button + twisting
the program knob will immediately jump to the CV input selection.
Each CV assignment includes its own digital attenuation and offset settings for
scaling the incoming voltage. To adjust this, hold the program encoder for >1 sec.
with the CV assignment selected. (To exit press the back button). When a CV is
assigned, a small bar graph will be displayed indicating the CV level (after
attenuation and offset).
The expected input voltage range in unipolar 0-5 Volts (Euro voltages outside of
this range won’t damage the module but will be ignored). CV control of program or
preset selection is not currently supported.
Externally Clocking
Some effects programs include a parameter for setting internal ‘INT’ or external
‘EXT’ clock. When external clock is enabled, the MFX then follows a clock pulse at
the ‘Clk’ input. Additionally, some effect programs repurpose the clock input as a
gate input for controlling special functions. See the Programs section for specifics
on how the clock input is used by each program.
