PHRASE TERRAIN

Epoch-Driven Sequence Navigator

• Generates complete original MIDI phrases up to 64 bars long, starting from a track header right-click rather than any existing clip
• Evolves each of eight generation parameters independently through a random walk, governed by an Anchor (starting value), a Min/Max deviation range, a Chance probability, an epoch interval (Bars), and a pattern length (Steps)
• Re-rolls each parameter at every epoch boundary, a point spaced Bars apart, with a Chance% probability of nudging the working value within its Min/Max range
• Adds up to seven additional polyphonic voices, each with its own scale-degree offset and independent drift range
• Pushes a single Bars, Chance, or Steps value across every parameter at once as a starting point before fine-tuning rows individually
• Splits the finished phrase into evenly sized segments and distributes them across Take Lanes for manual recompilation afterward

• Bars sets how often, in bars, a parameter gets a chance to evolve at all, the macro-level rhythm of when the phrase's character can shift
• Steps sets the length of the internal pattern that repeats within a single epoch, the micro-level rhythmic cycle between those shifts
• A short Steps value produces tight, repetitive internal patterns; a long Steps value allows more melodic and rhythmic variety inside each epoch before the next evolution point arrives
  
• Octave displaces individual notes up or down by whole octaves on top of the main pitch walk, at each epoch
• Transposition shifts the entire phrase, all notes at once, up or down in semitones at each epoch boundary, as if capo-ing a finished passage rather than altering the melody itself
• Transitions inserts a brief preparatory passage before an epoch change when its Chance is above 0%, smoothing the shift instead of letting parameters jump abruptly
