How can you create and blend synthetic trumpet and French horn sounds on the ARP 2600 using a sawtooth oscillator, the low-pass filter, ADSR envelope and different audio signal paths?

Learning the ARP 2600 by analysing patches

The ARP 2600 is an iconic synthesizer, and there is no shortage… read more

How does Pigeon Plink's continuous carrier-to-modulator ratio control work, and how can it be used for experimental FM synthesis in VCV Rack?

Introduction

Pigeon Plink is an FM-oriented oscillator for VCV Rack based on Kitchen Sink. The two modules share much of the same general approach to… read more

How Can ADSRs Create Smooth Transitions Between Voices?

Dynamic Voice Morphing with ADSRs and VCAs

Simple voice switching often creates abrupt transitions.

Many musical situations benefit from smoother changes.

One effective solution is to combine ADSRs with VCAs.

Beyond On… read more

How Can Multiple Voices Be Switched On and Off Automatically in a Modular Patch?

Voice Switching in Generative Modular Synthesis

One of the most effective ways to change the character of a generative patch is not by changing notes, rhythms, or timbres, but by changing which voices are… read more

How Can Quantized Notes and Pitch Glitches Have Different Dynamics?

Separating Quantized Melodies and Pitch Glitches with Different Envelopes

Once quantized and non-quantized pitch streams exist, they do not need to share the same dynamic behaviour.

The chapter presents a technique… read more

How Can Filters and VCAs Control Random Voltages?

Shaping Randomness with Filters and VCAs in Modular Synthesis

Many musicians assume that random voltages generated by a Sample & Hold module must remain completely random.

In reality, the character of randomness can be shaped and… read more
