Navigate logical layers of code changes, visualize relationships, and explore their blast radius. WalkthroughSamplePlayer now applies the default scale before submitting loaded audio and updates the processor’s pitch-preservation threshold when scale or root-note settings change. Macro period snapping and processor threshold handling are updated, with tests for two loop lengths. ChangesSample loop pitch preservation

Send an unnormalized duration to the processor.
When setScale() uses normalize, longestPeriod is not in seconds. The processor multiplies this value by sampleRate, so it uses the normalized scalar as a duration and classifies loop lengths against the wrong threshold. Preserve the unnormalized longest period and send that value instead.

Retain getValue() for compatibility.
This removes a public method. Existing callers that use macro.getValue() will fail after the upgrade. Keep getValue(): number { return this.value; } while adding the value getter, or document this as a major-version migration.

SamplePlayer now sends the loop-end macro's longest period to every processor after scale or root changes, so playback's pitch-preservation cutoff follows the loop-point snapping range. The processor converts seconds to fractional samples and keeps its 61 ms fallback until configured.

longestPeriodis normalized when normalization is enabled; sending it as seconds is only correct withnormalize: false. Retain the original duration to support normalization.getValue(); decide whether to retain an alias or document the API break before release.Summary by CodeRabbit
