Thinning out performance 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 performance 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

performance data, set this parameter to ALL. To thin perfor-

mance data of just one specific MIDI channel, select that

MIDI channel.

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 XP-80’s 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.
