Product Description
The ELECTRIC ORGAN voicecard makes internal
connections of the Bullfrog to emulate pipe organ, when
several notes are played together. It also illustrates the
principles of ADDITIVE SYNTHESIS. In additive synthesis
several simpler waveforms are mixed together to generate
more complex sounds. On this voicecard the pulsewave is
sent to the DIVIDER and all outputs of the divider are
mixed together with the original pulsewave and sent to
the VCF and then to the VCA. Both ENVELOPE
GENERATORS are involved in the same way as on the Acid
Bassline voicecard. As we figured out previously, the
DIVIDER divides an original frequency by even numbers
and as result produces a pitch that is even octaves down
form the original pitch. Faders on the voicecard determine
an amplitude of each suboctave. Set the VCA OFFSET all
way counter clockwise, PULSE OUT to the max. Push the
MANUAL GATE button to check the sound. Tweak settings
of the faders and observe the difference in the sound.
Tweak CUTOFF and RESONANCE knobs. Add some echo
by setting the DRY/WET knob to 12:00 and find the best
DELAY TIME and FEEDBACK settings. Now, connect the
keyboard and you are ready to perform Toccata and
Fugue in D minor
