Controls In Detail – standard operation
Clock In
The SQ8 requires a +5V clock signal. Each clock signal will advance the sequencer 1 step. When the last step is
reached, it resets back to the first step. Take the clock signal from a square wave LFO, Clock module or MIDI to Clock
converter.
Clock Thru
The clock signal appearing at the CLOCK IN socket is buffered and transferred to the CLOCK THRU socket, so it can
be daisy chained to another sequencer.
Reset In
A 5V signal in here will reset the sequencer to step 1.
Step 1 Out
Each time step one is played, the step 1 gate socket will go high (output +5V). This socket can be used to trigger
other devices, such as a cymbal sound at the start of each bar, or to trigger another sequencer. The step 1 out will give
a clock signal that is the main clock in divided by out.
CV Out
This socket will output a control voltage set by the pot for the current step. It can be changed in real time.
Gate Out
This socket will output a 5V gate signal at each step where the CV control is not at the zero position (i.e. Gate
‘on’).
Step Button
This allows the sequencer to be manually stepped by one step at a time whilst the clock is not running. It can also
be used to reset the sequence. As with most analogue sequencers, step it to the last step (8 or whatever is patched)
so that when you start the clock, the sequencer starts on position 1.
Note: The step button will only work when any clock input signal is at a low state (0V). So it will note work when the
clock input is high. This situation will note arise in normal use, as one would only normally use the step button when the
master clock is stopped (making the clock signal low). If the sequencer is being clocked by a clock divider, even when
the clock is stopped, it is possible that the clock signal may still be high until reseted.
CV / Gate pots / Range switch
The CV and Gate functions are built into a single combined pot/switch. Turning the pot fully left will turn the Gate
off. You will fell the switch click off.
There are 8 CV pots, 1 for each step. When the range switch is HI the range is approximately 0 to 10V, when LO
the range is approximately 0-5V. LO is best for use when controlling a VCO as this gives better abillity to fine tune each
step.
The CV pots have a built in Gate switch. Pull the knob out to turn off the gate for that step, push it in to turn the gate
on.
LED Indicators
There are 8 LED’s. These will light in turn to show step position.
