Method Detail

isBetweenInFrames

boolean isBetweenInFrames(int from,
                          int to)

Check if the position of this event is inside the duration specified in the parameter. See MetroTrack.progressCursor(int, List) for further information. This methods is called as a callback of JACKAudio processing; this method should return as soon as possible. The heavy processing that blocks for longer time than the current setting of JACK's frame rate causes JACK to XRUN.

Parameters:

from - Specifies the beginning point of the duration to check. The value is inclusive.

to - Specifies the end point of the duration to check. The value is exclusive.

Returns:

true if this event is inside the duration.

prepareBarOffsetInFrames

void prepareBarOffsetInFrames(int barLengthInFrames)

getBarOffsetInFrames

setBarOffsetInFrames
