Thinning out sequencer data – 12 Data Thin
Continuously variable controllers such as aftertouch, pitch
bend, and expression tend to create unexpectedly large
amounts of data when operated. Data Thin will strip out
redundant data to increase the amount of memory available
for the sequencer.
✳ Tempo changes and the way data changes will deter-
mine how much data can be thinned out before it has a
degrading effect, so a general rule is hard to state. Try
various different settings.
Target track
Selects the track(s) or Pattern(s) in which data will be
thinned.
TRK ALL: Phrase tracks 1–16 and the Tempo track
TRK 1–TRK 16: The specified Phrase track
PTN 001–PTN 100: The specified Pattern
Measure (From), for (to) (Editing area)
Specifies the area of measures in which data will be thinned.
Value
For thinning data which incorporates rapid changes, use
higher settings. If you don’t want to thin that much data
even though it is subject to rapid change, use lower settings.
Time
If you are thinning data that changes gradually over time,
use higher settings. If you don’t want to thin that much data
even though the changes are gradual, use lower settings.
Status
Selects the type of data to be thinned.
ALL: All following sequencer data types
P.AFT: Polyphonic Aftertouch
C.C: Controller numbers
C.AFT: Channel Aftertouch
BEND: Pitch Bend
Range
If P.AFT or C.C is selected for the Status parameter, use this
parameter to specify the area.
To thin all Polyphonic Aftertouch data, set “C-1–G9.” To
thin C4 Polyphonic Aftertouch data, set “C4–C4.” To thin
Polyphonic Aftertouch data from C3 to C4, set “C3–C4.”
To thin all Controller numbers, set “0–127.” To thin number
4, set “4–4.” To thin numbers from 3 to 14, set “3–14.”
Channel (MIDI channel)
Selects MIDI channel of the data to be thinned. To thin all
sequencer data, set this parameter to ALL. To thin sequencer
data of just one specific MIDI channel, select that MIDI chan-
nel.
<Procedure>
❶ Make sure that the Track Edit Menu display
(SEQ/TrkEdit) is up.
❷ Press [F6] (Menu) to select Menu 3, then press [F2]
(Thin) to call up the Data Thin display (SEQ/TrkEdit).
This display can also be called up by moving the cursor to
“12 Data Thin” and pressing [ENTER] on the Track Edit
Menu display (SEQ/TrkEdit). Or press the numeric keys [1]
and [2], then [ENTER].
❸ Move the cursor to Target track and select the track(s)
or Pattern containing data you want to thin.
❹ When assigning the editing area by measures, move
the cursor to “Measure” and specify the measure num-
ber at which thinning will begin, then move the cursor
to “for” to specify measure length to be thinned.
When using Locate positions, press [LOCATE], and move
the cursor to “From” to select the Locate number where thin-
ning is to start. Move the cursor to “to” and select the Locate
number where thinning is to end.
❺ Move the cursor to “Value” and specify the amount of
data you want to thin.
❻ Move the cursor to “Time” and set the time interval at
which data will be thinned.
❼ Move the cursor to “Status” to select the data to be
thinned.
If you select P.AFT or C.C, move the cursor to “Range” and
specify the area. For P.AFT, you can specify the key range by
pressing keys of the keyboard.
❽ Move the cursor to “Channel” and select the MIDI
channel of data to be thinned.
❾ Press [F6] (Execute) to thin out data.
