DIY MFOS VCF 24dB KB
We always recommend visiting the MFOS website before building where the latest 'offical' information and news can be found. Here on the Soundtronics website, you will find selected information from the MFOS site plus additional information and resources to aid the building and maintaining of your MFOS synth. This is not going to happen over-night but during the course of 2014, it will start to take shape as we document our experiences in the construction of these modules. We would also like to include any experiences, hints and tips from customers as well so feel free to contact us or simply post a comment using the form at the foot of this page.
Introduction to the MFOS VCF 24dB
Voltage Controlled Filters 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. This filter includes voltage controllable cut off frequency and resonance (or Q) that gives you more variables to play with as you experiment with sounds from your imagination. Additionally it provides inputs for a three-signal mixer.
