DIPs 5 & 6: Velocity Randomization Bandwidth
The keys of TPX2s/4s/6 are not velocity sensing, which means that the MIDI NOTE messages will be
sent from the unit with a constant velocity value. In some situations, constant velocity is preferable,
such as when controlling organ or harpsichord sounds; however, many patches will sound more
natural with some variation in the output velocities. To achieve more natural sounding output without
velocity sensing keys, a velocity randomization function may be used. DIP switches 5 and 6 control
the bandwidth of this randomization, from ± 0 to ± 15.

The velocity fader or pedal control is used to vary the overall velocity output. When either DIP
switches 5 or 6 are ON, the velocity fader value serves as the center of a randomized velocity band.
For example, if the velocity fader is located around the value 80, and setting 2 above is used (where
DIP switch 6 is ON), the velocity values in the output will vary randomly between 75 and 85. To
change the velocity randomization settings, turn the unit OFF, change the positions of DIP switches 5
and 6 to the desired function, and turn the unit back ON.
DIP 7: Global Pitch Bend Mode
Because the Tonal Plexus uses MIDI Pitch Bend to retune pitches, the conventional expectation of
Pitch Bend control is lost. However, the internal synthesizer allows global pitch to be altered using a
special MIDI Modulation Pitch mode, which is part of the Roland GS standard. Using a combination of
MIDI messages to initialize global transposition and Modulation parameters at startup, the
conventional Pitch Bend function can be imitated, in which the MOD Fader controls global pitch. In
