Options

BITS selects the bit-depth of the data sent to DAC.
RATE selects the refresh rate of the DAC. Note that a handful of models are internally
rendered at 48kHz (instead of 96kHz); so the difference between 48kHz and 96kHz might be
inexistent for the most complex models. Note also that reversely, to reduce aliasing, the
simplest models are rendered internally at 192kHz or 384kHz.
TSRC selects a trigger source. EXT. uses the gate/trigger jack; AUTO additionally tracks
changes in the V/OCT frequency input larger than a semitone and generates a trigger on
each of these. This allows, for example, the physical models to be controlled by a note
sequencer which does not provide gate outputs.
DLY applies a delay between the moment the trigger is received and the moment the note is
"struck" on the physical models. We have observed that some CV-gate converters or
sequencers sometimes have slow settling times, or have a short timing errors between the
refresh of their analog and digital outputs. Delaying the processing of the trigger allows the
physical model to sample the accurate CV rather than a fluctuating one – which can cause
unwanted glitches or portamento-like effects at note onsets.
TDST selects what happens when a trigger is received on the TRIG input. SYNC simply
resets the phase of the oscillator to zero. TIMB applies an AD envelope to the TIMBRE
parameter. LEVL applies an AD envelope to the signal level (like a digital VCA). Finally,
BOTH applies both a timbre and level modulation with the internal AD envelope.
TENV selects a preset shape for the internal AD envelope. This envelope is triggered by the
TRIG input, and its destination is selected by the TDST parameter described in the previous
paragraph.
META allows the synthesis model to be selected by the FM CV. When this mode is active,
frequency modulation through the FM CV input, its attenuvertor, and the FINE knob are no
longer possible – but is replaced by CV-controlled model selection. This option is great for
creating sequences featuring the different synthesis models. Keep in mind that
discontinuities might be heard when switching from one model to the other! The EDIT
encoder can still be used to scroll through synthesis models; and the CV applies to the FM
input allows you to scroll forward (positive voltage) or backwards (negative voltage) in the
list.
RANG chooses the range of the "coarse" knob. EXT. adjusts the range of this knob +/- 4
octaves around the note received on the V/Oct input. Because of this, when no frequency
CV signal is sent to the module (which would be the equivalent to sending a CV of 0V –
corresponding to a very low note!), the coarse button will have a bias towards low
frequencies, which might not always be desirable. FREE adjusts the range of the coarse
knob to +/- 4 octave centered around C3 (261.5 Hz). This setting is recommended when the
module is used with no external signal on the V/Oct CV input. XTND (extended) provides a
larger frequency range, but disables accurate V/Oct scaling as a side effect. The last option
(440) locks the oscillator frequency to 440 Hz exactly – helpful for tuning another VCO.
OCTV is a transposition (by octave) switch.
QNTZ applies a quantification to the incoming V/Oct signal. The frequency can either be
quantized to semitones or to quarter tones. It is still possible to create smooth modulations of
the frequency, such as vibratos, by using the FM input – which is not quantized.
FLAT applies a detuning in the lower and higher frequencies, to recreate some of the tuning
imperfections of VCOs.
