SWEEP
The SWEEP knob modulates VCF 1’s center frequency with
sawtooth waves from the LFO. SWEEP is a bi-polarity control. Its
zero position (no modulation) is close to straight-up 12 o’clock. Turn
SWEEP clockwise for falling sawtooth modulation. Turn SWEEP
counter-clockwise for rising sawtooth modulation.
Pulling the SWEEP knob up activates the multi-saw waveform. This
adds in a second sawtooth waveform at the TEMPO rate. The
resulting modulation shape depends on the relative setting of
TEMPO and LFO.
SHAPE
The SHAPE knob controls the symmetry of the PULSE and MOD
waveforms. It is similar to a swing ratio control. When SHAPE is
fully counter-clockwise, the modulations are symmetrical (no
swing). As SHAPE is rotated clockwise, the modulations will
become asymmetric.
SHAPE also controls the symmetry of the SLIDE effect. When
SHAPE is fully counterclockwise, the SLIDE effect has the same
crossfade time at every transition. Turning SHAPE clockwise makes
the even slides longer, and the odd slides shorter.
Pulling up the SHAPE knob disables its effect on PULSE and MOD
symmetry (no swing). SHAPE symmetry is still affected.
Modulation Controls
PULSE
The PULSE knob controls the depth of modulation to Drone
Commander 2’s lters. The pulse waveform can be as simple as a
square wave or a more complex combination of sloped and straight
line segments with syncopation and polyrhythmic character.
PULSE’s push-pull switch gives a quick change of tone when
contrast is needed. It can modulate either VCF 1 (the original Drone
Commander bandpass lter), or VCF 2 (4-pole low pass ).
Ÿ
In push position, PULSE modulates VCF1. VCF2 is biased to its
high frequency range (brighter tone).
Ÿ
In pull position, PULSE modulates VCF2. VCF1 is biased to its
middle range (darker tone).
Expander
: There is a patch point for the PULSE waveform ouptut.
Its amplitude is variable (post- PULSE knob).
Expander
: There is a patch point for SWEEP LFO output. Its
amplitude is variable (post- SWEEP knob)
The sweep effect can be varied with the SWEEP CV input. Position
the SWEEP knob straight up when using SWEEP CV IN.
TIP: When the clock is paused (TEMPO knob fully off), you can use the
PULSE knob as a cutoff frequency control for the 4-pole lter. Pull up the
PULSE knob. Turn PULSE counterclockwise for a darker tone. Note that the
cutoff frequency is still affected by the envelope generator.
