Clock Jack Function
 Ticks: The Clock Jack is expecting a standard clock signal. Hysteresis occurs at 2.5 volts. That is,
when the voltage on the jack rises above 2.5 volts, it is considered on, and when it drops below 2.5
volts, it is considered off. Any waveform of any pulse width can be used to clock the Trigger Man,
including, but not limited to square, triangle, and saw tooth waves. More complex waveforms may
give unpredictable and interesting results as they pass through the 2.5 volt hysteresis point. As soon
as a tick is detected, the Trigger Man switches over internally to expect an external clock signal.
When receiving external clock signals, the Tempo Knob acts as a clock divider. The external clock is
divided by 1, 2, 3, 4, 6, 8, 12, 16, or 32 as indicated on the panel. If you want the Trigger Man to be
clocked at the same rate as the incoming clock signal, just turn the Tempo Knob all the way to the
left to divide by 1.
When receiving external clock signals, pressing the Start/Stop button works differently. After an
external tick is received the Trigger Man is “running.” At that point, pressing Start/Stop resets the
Trigger Man to the first step, and it is not considered to be running. Pressing Start/Stop will then
restart the internal clock, which will continue to run until Start/Stop is pressed again, or an external
tick is received.
 Voltage Controlled Tempo: The Clock Jack is expecting zero to 5 volts, which will produce a clock
rate of 40 to 295 BPM, just like the Tempo knob does. A voltage over 5 volts is interpreted as 295
BPM. If the Clock Jack function is set to VC Tempo, and nothing is plugged into the jack, the Tempo
will always be 40 BPM. When the Clock Jack Function is set to VC Tempo, the Tempo has no effect.
VC Tempo is not the same as an external clock; it merely sets the speed of the internal clock. The
Start/Stop button functions normally.
Control Jack Voltage Controlled Pattern Change
When in Pattern Play mode, a voltage on the control jack sets the currently playing pattern. The control
jack is expecting zero to 5 volts. The 5 volt range is divided into 9 equal divisions of approximately 0.55
volts. A voltage under 0.55 volts has no effect on the currently playing pattern, just as if nothing was
plugged into the control jack.
 On First Step: The currently playing pattern, as determined by the voltage on the Control Jack,
changes on the first step. Voltage changes during the playing of the sequence are ignored.
 Immediate: The currently playing pattern changes immediately in response to the voltage on the
Control Jack. The current step does not reset to the first step when that happens, the pattern
changes right away. Immediate changes to the currently playing pattern can produce chaotic
results, which may or may not be desirable.
