Detailed Description

Step sequencer-style LFO with programmable values per step.

StepLFO provides a stepped low-frequency oscillator where each step can have an independently programmed value. Unlike smooth LFOs, this creates stepped/ quantized modulation patterns useful for rhythmic effects and sequenced modulation.

Key Features:

Configurable number of steps
Independent value per step (-1.0 to 1.0)
Adjustable frequency (rate)
Phase reset on note-on for tempo-synced patterns
Constant output per step (no interpolation)

Usage:

StepLFO stepLFO;
stepLFO.setSampleRate(44100.0);
stepLFO.setNumPoints(8); // 8-step sequence
stepLFO.setFreq(2.0f);   // 2 Hz (complete cycle every 0.5 seconds)
 
// Program step values
stepLFO.setPoint(0, 1.0f);   // Step 1: max
stepLFO.setPoint(1, 0.5f);   // Step 2: half
stepLFO.setPoint(2, 0.0f);   // Step 3: center
stepLFO.setPoint(3, -0.5f);  // Step 4: negative
stepLFO.setPoint(4, -1.0f);  // Step 5: min
stepLFO.setPoint(5, -0.5f);
stepLFO.setPoint(6, 0.0f);
stepLFO.setPoint(7, 0.5f);
 
stepLFO.noteOn(); // Reset to beginning
 
// In audio callback
float modValue = stepLFO.process(numSamples);
