Thin Out - Yamaha QY100 Owner's Manual

"Thins out" specified types of data by removing every other event of
the specified type. This is particularly useful for reducing the volume of data
required for pitch bends, aftertouch and other control change operations,
thus making more efficient use of the available memory.
Data type
parameter
The "TR" parameter selects the track to be affected by the Thin Out
job: "01" ... "16" for the sequencer tracks, or "Tm" for the tempo track.
The "M" parameters above the graphic bar are used to specify the
first measure:beat and last measure:beat of the range to be modified.
The data type parameter determines the type of data to be thinned.
