Introduction to Modular with Bread Modular

Bread Modular is a modular synth platform built from scratch. Unlike VCV Rack, which is based on the Eurorack standard, Bread Modular takes a completely different approach. However, the core concepts you've learned still apply.

This guide will help you map your modular knowledge to Bread Modular.

0. About Bread Modular#

1. You can power a Bread Modular case over USB-C, making it truly portable.
2. Both headphone and line-level outputs are built into the base.
3. You can host up to 12 modules in a single base.
4. Most modules accept MIDI, giving you more control with fewer cables.
5. The platform runs on 3.3 V, so analog circuits such as Moog-style filters and noise generators are harder to implement; we often rely on digital solutions instead.
6. It is more affordable than Eurorack, though it is still expensive.

1. Supersaw Oscillator#

The 8bit Supersaw oscillator is a good starting point. It has two sawtooth oscillators running one octave apart.

The diagram above shows how to patch modules in Bread Modular and the recommended knob positions for this setup. Hover over a knob to see how changing it affects the sound.

It also indicates any available mode states. In this patch, it highlights the MODE LED.

2. Mixing with Noise#

Here we mix noise with the Supersaw oscillator to create a more complex waveform.

3. Using a Filter#

Here we use a filter to shape the Supersaw sound.

4. Using Overdrive#

This patch builds on the previous one, but the SVF output now runs through an overdrive module.

Increase OD1, OD2, and GAIN to hear how the overdrive reshapes the sound.

5. Let's Use an LFO#

This patch is similar to the previous one, but the SVF cutoff frequency is modulated by an LFO.

Here, the LFO is an 8bit module running the LFO firmware.

6. Using a VCA#

Here we control a VCA with an LFO.

7. Using an Envelope#

Here we use an envelope to control the VCA, with MIDI triggering the articulation.

The LFO isn’t part of this patch, so try routing it to the SVF cutoff for additional movement.

With these building blocks, you can translate your modular experience to Bread Modular and start exploring more advanced combinations. Happy patching!
