Welcome to Learning Modular: a site for musicians and sonic dabblers alike who are new to modular synthesis. Here you will find a growing list of in-depth articles, thoughtful musings, and videos on subjects such as choosing modules for your system, and putting them to work creating both new and familiar sounds.
The Synthrotek Verb is a lo-fi reverb module based on a trio of PT2399 delay chips set up as a resonator to simulate vintage reverb effects. One of its more unusual features is a voltage-controlled Mod parameter, which alters the tuning of the three delay lines. When...read more
The Sputnik Modular West Coast Random Source is a very capable Eurorack-format update on the classic Buchla Source of Uncertainty module. In this movie, I focus first on uses for those 1:2 switches, including using them to send alternating note-on gate or triggers to alternating drum sounds. Then I move on to showing the sample and hold itself, first with the typical “science fiction soundtrack” random pitch technique, and then for something more subtle such as randomly changing the pulse width.read more
A favorite “West Coast” module that synthesists of all tastes should check out is the LPG: the low-pass gate, which acts like a VCA but with a filter element that also dampens the high frequencies. A new “hybrid” application I’ve found LPGs to be useful for is to process the output of dedicated percussion modules. An LPG naturally damps both the amplitude and harmonics of the input to mold most sounds into a typical percussive shape, freeing you up to dial in the initial noise and harmonic mix you like without worrying about the original sound ringing out too long or taking up too much room frequency-wise in a mix.read more
You hear many users search for an “extreme” filter to add to their system, looking for one that is unstable when pushed, screams when provoked, and otherwise makes their instrument more aggressive, less predictable, and in general fun to play with (if you’re the type of person who likes to play with knives). Filters based on the Vladimir Kuzmin’s design in the Russian Polivoks synthesizer fit this description. My favorite variation of the classic Polivoks design in the Erica Dtech VCF, which extends the original design. In this video, I explore how to push the Dtech filter into unstable, aggressive territoryread more
