You may wonder - what's that strange connector on the top of the Bullfrog? This is the VOICECARD slot. Voicecards expand functionality of the Bullfrog and make it even more versatile. Essentially, the voicecards replace patch cables - they connect the "modules" of the Bullfrog internally. But that's not all about them - some voicecards have built in mixers, signal generators and advanced electrical circuits to control the synthesiser, for example, sequencer that sends CV to control pitch and gate to start events on the synthesizer (Figure 40). When inserting voicecards, make sure, the front panel of the voicecard faces the main interface of the Bullfrog. It is recommended that you turn off the Bullfrog when inserting a new voicecard. The WIND AND STARS voicecard makes internal connections of the Bullfrog so that it automatically emulates randomly evolving wind sound and blinking stars are controlled by the divider. Toddlers fall asleep better when they hear sounds like these. The NOISE is patched into VCF and the VCF is patched to VCA. Set the VCA OFFSET to 12:00, ENVELOPE GENERATOR 1 to LOOP mode, NOISE LVL all way clockwise. Then manipulate SAMPLE & HOLD RATE setting, VCF CUTOFF, RESONANCE and CV 1 LVL settings, and well as ATTACK 1 and RELEASE 1 settings. Add some echo by setting the DRY/WET knob to 12:00 and find the best DELAY TIME and FEEDBACK settings. Enjoy and goodnight!
