Signal flow

Signal flow is the path a signal takes through your patch.

The simplest version is audio going from a source to the speakers.

Sources and effects

Section titled “Sources and effects”
  • A source creates signal, like osc, const, mic, or sampler.
  • An effect changes signal, like flt, amp, dly, or reverb.
  • out is the final sink.

Audio and control

Section titled “Audio and control”

In blzr, a handle can carry audio-rate signal or a slower control signal depending on what you connect.

That is why the same graph language can describe sound generation and modulation.

For example:

osc -> out

is audible signal flow, while

const -> osc.detune

is control flow changing another node.

Visual convention

Section titled “Visual convention”

blzr enforces a consistent visual layout:

  • Audio signal flows top to bottom — sources at the top, out at the bottom.
  • Control signal (CV) flows left to right — modulators like const or midi sit to the left of their targets.

Press Space l to automatically relayout your patch following this convention. If you have nodes selected, only those nodes are rearranged.

Why this matters

Section titled “Why this matters”

Once you understand signal flow, filters, envelopes, LFOs, and MIDI routing all become easier to read.
