Weekend Studio Fun

I decided to stay home this weekend. I stopped by Control in Williamsburg and picked up a new module for my Eurorack system. I bought a Toppobrillo Multifilter. You can hear it in the above videos filtering a Wiard Oscillator, Make Noise Echophon and a iPad Police Scanner. The clock and drums are from a Korg Rhythm 55. An Analog Solutions Telemark is providing some LFO modulated white noise snares and a Korg Monotribe is joining in with some resonant rides and a synth line. Both the Telemark and Monotribe are being pinged by an Intellijel uStep. There’s also an Intellijel uVCA and Pittsburgh Modular ASDR doing some utility work. There’s won’t end up as songs as sometimes it good to just play around.

“The so-called state-variable filter has a long history in electronic music- traditionally the most versatile voltage-controlled filter at any analog synthesist’s disposal. there were several classic design examples and variants produced throughout the heyday of analog synthesis, such as those implemented in the Oberheim SEM, the EDP Wasp, and the fabled,albeit lesser known filters such as the famous Serge filters and Arp 1047; the classic SVF configuration is simple and versatile- with several different filter responses available simultaneously ‘for free’ by nature of it’s design with no elaborate mixing schemes. traditionally there have been some considerations when designing a wide-range filter with variable Q using this topology, for instance, relative instability/ generally poor sound and behaviour at very high Q, many designs get around this by limiting the maximum Q available, among other things. those that are designed to allow for self-oscillation will often become unstable at the threshold and have inconsistencies initiating or mantaining oscillation across the entire audio range. The Toppobrillo Multifilter is a new/ traditional state-variable design based on a great modern quad VCA chip, the SSM2164. this, in part, helps make the Multiflter what it is, a clean, quiet, stable and very controllable filter at it’s core, without limiting its palette, well suited for processing anything you can run through it.” – toppobrillo.com
