Erica Synths

Notes: We wanted to organize patch cables that were hanging on all possible objects in our Lab, therefore we decided to make patch cable holders.

Rigid, 2mm aluminium powder coated cable holders can host over 100 patch cables in perfect order! Two screws for fixing the cable holder are included.

Notes: 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 synthesiser.

When inserting voicecards, make sure, the front panel of the voicecard faces the main interface of the Bullfrog. It is recommend that you turn off the Bullfrog when inserting a new voicecard.

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. 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.

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!

As it's name suggests, the HIGHPASS VCF voicecard expands the sound treatment capabilities of the Bullfrog by bringing a highpass filter into the game. This allows for exploring highpass and bandpass filtering. The voice card features typical VCF controls - CUTOFF frequency, RESONANCE and CV LEVEL. The CV source switch allows for selecting between three CV sources - envelope generator 2, Sample & Hold LFO, which is a pulsewave generator in the Sample&Hold "module". The voice card features internal audio connections - the output from the MIXER is patched into the highpass VCF, the output of the highpass VCF goes into the input of the onboard lowpass VCF which is then connected to the VCA. For more flexibility, no CV connections for the Bullfrog are present on the voice card, so you have to do the patching yourself.

Notes: Rack ears to install your SYNTRX in a studio deck.

Replace wooden side panels with rack ears and integrate the SYNTRX in your studio rack.
