Specifications

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).
