Second Oscillator, or Waveform Animator?

Second Oscillator, or Waveform Animator?

Many semi-modular synths have just one VCO. They usually feature a square wave with pulse width animation, but if you want to use the sawtooth wave instead, the sound can be rather static. A common addition is a second oscillator; an interesting alternative is a “waveform animator.”

Patching a Ratcheting Sequence

Patching a Ratcheting Sequence

Ratcheting is a Berlin School sequencing technique where an individual note in a sequence has its envelopes retriggered multiple times, usually at a musical subdivision of the sequence’s tempo – such as playing 1/32 notes in the middle of an 1/8 note sequence – to create a roll. Although used since the 70s, not everyone knows how to create a ratcheting patch on their modular. In this article I demonstrate creating and performing several typical ratcheting patches.

Matching Octaves in Your Modular

Matching Octaves in Your Modular

Different oscillators and MIDI to CV converters may have varying ideas of what voltage a given note produces, and what pitch should you hear as a result. If there is a difference, in most cases it can be dialed out with a pitch knob or transpose switch. However, there are occasions when you need the assistance of an additional module to settle these disagreements.

Multiples: Passive, Buffered, and Logic

Multiples: Passive, Buffered, and Logic

Sometimes, you need to send a signal to more than one place. With Eurorack in particular being a small format to begin with, it’s not common for a module to have multiple outputs to cover you, so you need to find a way to split the signal yourself. There a few ways to do it, some with disadvantages you may not have been aware of.

Choosing Utility Mixers for Your Modular

Choosing Utility Mixers for Your Modular

When you’re configuring your modular synthesizer, it’s easy to leave out the all-important utility modules that will help glue together a patch as well as open up creative options. In this note, we’re going to talk about what I call “utility mixers” – not the final mixer with optional effects sends and the such, but tools to combine signals in the middle of a patch.
