When listened to dry the overall effect is like an odd form of panning and vibrato at the same
time. But when the balance pot is turned to around 50% a subtle chorus sound is heard.
Stereo Ensemble Mode
This mode is similar to the dimension mode but features four LFOs and not just two. Instead
of the right hand BBD being modulated by the inverse of the same LFOs that control the left
hand side, this time the right hand BBD gets its own pair of triangle and sinewave LFOs.
However, these LFOs are not completely independent of the left hand side ones. The rate and
frequency controls are shared with the left hand LFOs. Therefore the right hand side LFOs
will track the frequency and amplitude of the left hand side LFOs. The only difference between
the two sides are that the right hand side LFOs always run 20% faster than the left hand side.
This keeps things relatively stable across the stereo panorama, yet, because of the free running
nature of all four LFOs, things are different enough between the channels to give a wide
ensemble sound.
Quad Ensemble Mode
The RS or VP ensemble mode. The third mode is the most complex. The basic behaviour is
the same as the stereo mode, but the quad mode adds an extra BBD line to each stereo
channel. This additional BBD is only controlled by the triangle LFO and not the sine wave
LFO. However, it responds inversely to the other BBD on its channel. So as the other BBD is
increasing in delay, the extra one is decreasing. And because it doesn't respond to the sine
wave LFO, the output of the BBD can be very different to the other BBD on the same
channel. This creates a rich rolling sound. The classic RS or VP string sound involves only the
effected sound, ie. 100% wet. The triangle wave LFOs being set to fairly slow (one cycle
around 5 seconds) but deep modulations. And then with a much smaller amount of faster
(around 5Hz) sine wave modulation added.
POWER LED
This will light when power is applied to the unit. To be precise, it lights when the positive
power supply rail is up and running.
OUTPUT LEVEL
This adjusts the output level of the unit. The gain of the whole module is +6dB when being
driven with an unbalanced audio signal.
