MFOS Euro Multimode VCF (Silver)

We acquired music from outer space in 2016 in order to carry on the great work of ray wilson-- and we are proud to announce another module in the series of new mfos eurorack modules, the multimode vcf

We've taken ray's design and brought it up to date for eurorack:

- conversion to DIY-friendly SMT design for most pcb parts

- retained certain through-hole parts to help maintain that classic analog richness (styrene cap, tempco resistor, et al)

- aluminum panels in a beautiful new design aesthetic by grayscale, 14hp wide

- 'either way' eurorack power circuitry (by neutron sound) to eliminate the risk of cable reversing- no blown ICs!

- all pcb-mounted panel components- pots, jacks, leds and switches-- no hand wiring!

If you are relatively new to modular synthesis, this would be a great choice!

- there is a lot of documentation about the construction, calibration, testing and operation of this module, including the legacy filter, of which thousands have been made

- it's designed to be DIY-friendly with 'large' SMT parts (SOIC, 0805 and 1206 packages)

- it's the filter foundation for a full modular synth rig, with the forthcoming MFOS eurorack modules to create a cohesive, classic analog synth in 84hp or 104hp 

- the functions are 'foundational'-- learn the capabilities of 'basic' filter functions

if you're still intimidated by DIY SMT soldering, we'll offer the pcbs, bundles and kits with SMT parts pre-soldered for you. 

full kits include everything you need!

• State Variable VCF 12dB/Octave With VC Resonance
• Simultaneous High-Pass, Low-Pass and Band Pass Filter outputs.
• Log Response to Control Voltage (1V/Oct Tunable)
• Sine Wave Oscillator at full resonance
• Voltage Controlled Resonance (Linear control)

From Ray Wilson: 

"Voltage Controlled Filters are, in my opinion, one of the coolest modules in any synthesizer. They can subtract or add harmonics from the original signal and dynamically change the harmonic content as they are swept by external control voltages or track the keyboard voltage used to control your oscillators. I love the sound of a couple of oscillators tuned low and close to unison put through a low pass filter with a fair amount of resonance. As you modulate the cut off frequency (also in the low range) it has the sound of an airplane passing overhead or a hoomy singer modulating the frequency content of their droning chant by formant filtering with the mouth and throat. And of course white noise through a slowly modulated resonant filter sounds like you're out on the frozen tundra. This filter includes simultaneous high-pass, low-pass and band pass outputs, voltage controllable cut off frequency and resonance (or Q) giving your imagination even more variables to play with as you experiment with sounds. Additionally it provides inputs for a three-signal mixer. "
