In Part 2 of Pyramind’s Synthesizer Architecture Workshop, instructor Quinn Grodzin goes deeper into modulation, signal routing, clocking, MIDI control and multi-oscillator synthesis using VCV Rack.
Building on the foundations from Part 1, this session explores how modulation sources interact, how LFOs can be synced to clock signals, how multiple oscillators can be layered and detuned, and how the same concepts translate directly into modern software synthesizers and DAWs.
Part 2:
Understanding LFO Shapes and MIDI Controls
• MIDI keyboard aftertouch
• Modifying LFO waveforms with hardware controllers
Syncing LFOs with Clock Signals
• Connecting clock signals to LFOs
• Clock division and tempo syncing
• LFO hardware modules in software
• Precise modulation with clock modulators
Advanced Signal Routing
• Combining multiple modulation sources
• Adding a second oscillator
• Fine-tuning detuning
• Octave switching and oscillator layering
Signal Flow & Modulation Techniques
• Audio signals vs. control signals
• Automating waveform switching
• Pulse-width modulation for thicker sounds
From Modular to Modern Synths
• Mapping modulation in Ableton Wavetable and Analog
• Polyphony and multi-voice routing in VCV Rack
• Applying modular concepts to sound design across different synthesizers
Understanding these concepts gives you a transferable framework for working with almost any synth — hardware, software or modular.
The goal is not simply to learn VCV Rack. It’s to understand **how synthesis works underneath the interface** so you can design sounds with greater intention and confidence.
Develop your sound. Deepen your craft. Tell your story. Find your people.
