Rubicon
2
Manual
B. SYM attenuator - You can modulate the SYMMETRY value with a control signal
patched into the Rubicon
2
SYM input . The SYM attenuator adjusts the extent to which
that control signal is added to the value set with the SYMMETRY knob .
NOTE: External CV control of SYMMETRY is possible even with the LOCK switch
turned on (up position).
C. REV/FWD LEDs - These lights indicate whether the oscillator is running in the standard
“forward” direction, or if it’s running in reverse. Every time the oscillator switches
direction, it’s performing thru-zero FM.
D. LOCK switch - This switch enables the Rubicon
2
to function as a perfectly symmetrical
Thru-Zero FM oscillator without significantly changing the oscillator’s output pitch or its
v/oct tracking accuracy.
When you switch on LOCK (up position), the Rubicon
2
ignores the position of the
SYMMETRY knob, internally setting it to a balanced position while simultaneously
adding compensation voltage to bring the oscillator back to its original base frequency.
Using the LOCK switch, you can directly compare the sound of Linear FM and TZFM
without having to re-tune your oscillator or suffer v/oct tracking issues. Specifically, with
the
SYMMETRY knob fully clockwise and the LOCK turned off (switch is down), then
Rubicon
2
produces standard Linear FM. If you then turn on LOCK (switch is up), it
produces Thru-Zero FM (TZFM) at the same frequency as Linear FM.
NOTE 1: When LOCK is on, turning the SYMMETRY knob has no effect, however CV
control of SYMMETRY is still possible.
NOTE 2: At higher frequencies, engaging the LOCK switch can have a minor effect on
the output pitch. For this reason, you should keep the LOCK switch turned off if you’re
not frequency modulating the Rubicon
2
via its TZFM input.
