Modular synthesizer enthusiasts looking for a complete system capable of extreme sounds will be impressed with the erica synths Fusion System II, a Eurorack modular system that uses vacuum tubes to create a wide range of sounds that are deep, saturated, and complete with unprecedented pressure.
The system is housed in a 104 HP skiff case with a lid and provides 63 patch points for extensive experiments in sound design with an all-analog signal and CV path. The system consists of two Fusion VCO2, a Fusion VCF3, a Fusion Modulator, a Fusion VCA/Waveshaper/Ringmodulator, and a Fusion Delay/Flanger/Vintage Ensemble. A set of 20 patch cables and an external power supply are included.
Modular synthesizer enthusiasts in search of massive analog sound source will be thrilled with the erica synths Fusion VCO V2, a full analog VCO with a ton of distinct features. Based on the highly stable AS3340 circuit, the provides three simultaneous waveforms which track great over 8 octaves.
The VCO is coupled with a transistor-based suboscillator and detune function, which utilizes two BBD delay lines that function as a frequency shifter that mimics two detuned VCOs. The tube crunch knob provides distinctive tube overdrive, while an external input mixes an additional signal with the principal oscillator, resulting in sonic mayhem. The module includes a power ribbon cable and a set of mounting screws.
- Full analogue design
- Great tracking over 8 octave range
- Detune function for thickening the sound
- -1 oct transistor based suboscillator
- Tube overdrive circuit
- External audio input
- VCO synchronization
- Simultaneous waveform outputs
- Power consumption: +228mA / -55mA
- Module depth: 1.7" / 42mm
Modular synthesizer enthusiasts in search of a unique filter with tons of character will be thrilled with the erica synths Fusion VCF3, a Eurorack compatible analog voltage-controlled low-pass filter that utilizes a vacuum tube and vactrols to provide a distinct soft-filtered sound.
Some special features include an independent 3-channel audio mixer and a 1x3 buffered multiple that splits a signal into three outputs. A CV recorder records the motion of the potentiometer, so you can design advanced filter modulation patterns and even use the recorded CV and gate elsewhere in your system. The module includes a power ribbon cable and a set of mounting screws.
- Full analogue design
- Vacuum tube and vactrol based filter circuit. (Because of vactrol lag, the VCF will not accept audio rate modulation. The maximum modulation frequency is 10Hz)
- Input signal mixer with gain 2 for signal overdrive
- Buffered multiple for splitting audio and CV signals
- Potentiometer motion record unit with CV and gate outputs
- Record CV motion 0 to +5V
- Multiply and Divide CV playback: past 12 o'clock multiplies the recorded CV playback by 2, 3, 4, and 8; before 12 o'clock divides the recorded CV playback by the same amounts
- Power consumption: +160mA / -10mA
- Module depth: 1.4" / 36mm
Modular synthesizer enthusiasts in search of a complex modulation source will be thrilled with the erica synths Fusion Modulator, a Eurorack-compatible all-analog modulation source with tons of inspired functions. The Fusion Modulator features two EMS Synthi functionality inspired looping envelope generators with simultaneous unipolar (0 to 10V) and bipolar (-5V to +5V) outputs, VCA, noise generator, and sample-and-hold circuit.
The Fusion Modulator is a versatile modulation source for advanced modular setups, especially drone-music-oriented ones. The module includes a ribbon power cable and a set of mounting screws.
- Full analogue design
- Two looping envelope generators with Attack, On, Decay, and Off time control
- CV control over Decay time
- Simultaneous unipolar (0 to 10V) and bipolar (-5 to +5V) envelope outputs
- Manual trigger button
- End-of-cycle output
- VCA with the offset control
- Zener-diode-based white-noise source
- Sample-and-hold circuit with internal and external clock source
- Attack time: 6 to 850 ms
- On Time: 0 to 1.5 sec
- Decay Time: 16 ms to 2 sec
- Off Time: 14 to 1.3 sec
- Sustain Level: +10V
- Power consumption: 125mA at +12V / 74mA at -12V
- Module depth: 1.4" / 36mm
- Panel width: 22 HP
Modular synthesizer enthusiasts in search of analog time-based effects with tons of character will be thrilled with the erica synths Fusion Delay / Flanger / Vintage Ensemble, a distinct multifunctional analog effects module that combines BBD chip-based effects with an adjustable tube overdrive in the delay output with a feedback path for extra thickness of the sound.
The flexible low-pass filter is fully adjustable from none to extreme. The Vintage Stereo Ensemble is an effect that's common on vintage synthesizers to create a moving and thick spatial sound from a monaural tone generator. The module includes a power ribbon cable and a set of mounting screws.
- 2 BBD chips (1024 and 4096 stages)
- Delay and Flanger effects
- Vintage Ensemble Stereo effect
- Tube overdrive in the delay output and feedback path
