MIDI SysEx: Off, On— When On, the synth will respond to received MIDI
SysEx messages, and will transmit them, when prompted, to the MIDI Out. See
Sysex Messages on page 56 for details.
MIDI Out Select: Out, Thru— MIDI Out can be switched to MIDI Thru to
daisychain multiple MIDI devices.
Poly Chain: Off, Out 1, Out 4, Out 5, Out 8, Out 12, Out 16 —Used to expand the
polyphony via the Poly Chain output and one or more DSI synths—Mopho,
Tetra, or Prophet. See Using Poly Chain on page 37 for more information.
Local Control: Off, On— When on (the default), the keyboard and front panel
controls directly affect Mopho x4. When off, the controls are transmitted via
MIDI but do not directly affect the “local” synth (that is, Mopho x4). This is
primarily useful for avoiding MIDI data loops that can occur with some external
sequencers.
Audio Out: Stereo, Mono—
Mopho x4 defaults to stereo operation. When set to
Mono, this parameter defeats all pan settings and modulation, effectively
making each of the outputs a mono output.
PotMode: Relative (default), Passthru, Jump— The rotary controls on Mopho
x4’s front panel are a mixture of “endless” rotary encoders and potentiometers
or “pots.” The pots are identifiable by their lined knobs and the fact that they
have about 300°of travel. There are three pot modes to determine how the synth
reacts when the programmable parameters are edited. (Master volume is not
programmable, so these modes don’t apply.)
When set to Relative, changes are relative to the stored setting. In Relative
mode, the full value range is not available until either the minimum or maximum
value and the respective lower or upper limit of the pot’s travel is reached.
For example, the R
ESONANCE
parameter has a value range of 0 to 127. Let’s say
the physical position of the R
ESONANCE
pot is the equivalent of a value of 100.
If you switch to a program that has a stored Resonance setting of 63 and turn the
pot all the way up, it will only go to 90. To get to the maximum value of 127,
you first have to turn down until the value is at the other extreme and the pot is
at the limit of its travel (in this case, 0 and fully counter-clockwise,
respectively).
In Passthru mode, turning the pot has no effect until after the edited value equals
the preset value (that is, until the edited value “passes through” the stored
value).
