build_for()

void MayaFlux::Kriya::SamplingPipeline::build_for

(

uint64_t

milliseconds

)

Finalize configuration and start processing for a bounded duration.

Converts milliseconds to pipeline cycles via sample rate and buffer size, then starts execution for exactly that many cycles. When the cycle count exhausts, the pipeline stops unconditionally regardless of voice state. Any active voice is cut immediately with no fade or drain.

Must not be called if build() has already been called.

Parameters

milliseconds

Duration in milliseconds.
