◆ m_fUsedTickSize

float m_fUsedTickSize

private

TransportPosition::m_fTickSize used to calculate m_nNoteStart.

If m_nNoteStart was calculated in the presence of an active #Timeline, it will be set to -1.

Used to check whether the note start has to be rescaled because of a change in speed (which occurs less often and is faster than recalculating m_nNoteStart everywhere it is required.)

This member is only used by the #AudioEngine and #Sampler during processing and not written to disk.
