Analog and digital synthesizers

Synopsis
Modular synthesizers changed music making, starting in the 1960th. Many models have been developed over the past decades. The 6-day workshop will cover some of its history but mainly use the digital clone VCV Rack to teach the building blocks of synthesis. Each student will learn patching principles with oscillators, filters, envelope generators, etc., to build essential sound production patches. From there, we will develop a more complex improvisation environment with several sound layers and real-time parameter control. The final project is a live improvisation using the virtual synthesizer they constructed.

Aims
Students will understand sound synthesis more deeply with just a small set of digital tools. By the end of the course, students will have created their synthesizer environment and can improvise with it. Critical listening and feedback throughout the week encourage risk-taking and develop confidence in the student’s artistic and technical abilities.

Presentation
The last day offers the opportunity to showcase each student’s work with group feedback. Participants should outline their creative process and reflect on elements that were easy to integrate and the direction they wish to take in the future.

Prior knowledge
No prior knowledge of sound synthesis is required. Knowledge of a Digital Audio Workstation like Reaper, Logic, Ableton Live, Cubase, is beneficial.

Schedule (can be adapted to institutional needs)
There are typically two lectures daily, followed by individual, practical work. 

 

Lecture 01

Building blocks of sound synthesis, Introduction to the VCV Rack environment, creating a user account, downloading libraries

practical work:

Use the first introduction patches to familiarize yourself with the environment. Create a simple patch with VCO, LFO, VCF

Lecture 02

History of synthesis, overview of module types

practical work:

use the remaining introduction patches to understand gates, triggers, etc.

Lecture 03

Complex oscillators: Tidal and Macro Oscillators

Practical work:

create an evolving sound texture with these two oscillators, use LFN and slow LFO to shape micro and macro time

Lecture 04

Complex oscillators: Texture synthesizer, Granular Synthesis

Practical work:

augment the evolving sound texture with these two oscillators, use again LFN and slow LFO to shape micro and macro time

Lecture 05

sequencers and clocks, mixers

Practical work:

use traditional and stochastic sequencers to control your sound textures, combine sounds with mixers

Lecture 06

mixers with sends, reverb and controlled sends to effects

Practical work:

incorporate effects

Lecture 07

organizing sounds into layers, mute unused strips, MIDI control, multiple parameter mapping

Practical work:

Map your layers to an external MIDI controller, reorganize your instrument into a playable patch

Lecture 08

intermodulation, polyphony, delay feedback, audio feedback

Practical work:

augment your instruments to create polyphonic voices

Lecture 09

introduction to my personal improvisation environment

Practical work:

finalize your improvisation environment and sketch a plan for a 3-minute piece, practice a performance

Lecture 10

extending the work environment with sound sends to a DAW, automating parameter control

Practical work:

using the Blackhole sound driver, we will send the sound results into Reaper and understand how to automate sound control inside the DAW to compose, beyond an improvisation

Day 6

Presentations, critique, and final discussion
