DIY MFOS VCA Log / Lin 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 VCA Log / Lin
VCAs are essential to your synthesizer. They provide ring modulation effects, stereo panning, delayed vibrato, not to mention the normal envelope shaping of your sounds. This VCA works nicely with 10V PP (+/-5V) signal levels. If you are using +/-15 volt supplies you will probably need to mess with some values to get this to work for you.
Features
- Log and Linear Response to Control Voltage
- DC Coupling Throughout
- Excellent for Ring Modulation Effects
- Power Supply Range +/-9V up to +/-15V
