Per-Split Settings
Overview

Per-Split Settings are settings that generally need to have different values for each of the two keyboard splits. For example, MIDI Channels is a Per-Split Setting because the left and right splits need to send over different MIDI channels.

To view or change the Per-Split Settings, press the Per-Split Settings button and the button will light. Now notice that all the lights on LinnStrument's playing surface have changed:


Now the upper four rows of lights indicate the status of the Per-Split Settings printed directly above each column. For each column, the status of the uppermost printed setting is indicated by the uppermost note pad; the status of the second-from-top printed setting is indicated by the second-from-top note pad; etc. For example, if the highest note pad in column 1 is lit, this indicates that "One Chan" is selected.

The Per-Split Settings button has both momentary and toggle action:

If held for more than 1/2 second, it is momentary, staying on only as long as you hold it. This is use for fast changes: hold Per-Split Settings, change a setting with your other hand, then releasing Per-Split Settings.

Or if tapped briefly (held less than 1/2 second), it toggles between on and off with each press. This is better for one-handed use: turn on Per-Split Settings, change a setting, then press Per-Split Settings again to turn it off.

Each of the Per-Split Settings is explained below.


Select Split
(columns 15 & 16)

The Per-Split Settings screen includes two sets of settings-- one for the Left Split and another for the Right Split.

If LEFT is selected here, the settings in the leftmost 14 columns apply to the Left Split.

If RIGHT is selected, the settings in the leftmost 14 columns apply to the Right Split.

Also, when Split mode is off, the entire playing surface will use either the Left or Right Split's settings, depending on which Split is selected here. And you can quickly switch between them while playing by double-tapping the Split button.

 


MIDI Mode
(column 1)

There are three different ways that LinnStrument can send its MIDI information:

1) One Chan (One Channel)
All touches are sent over a single MIDI channel, called the Main channel. This is LinnStrument's default setting, making it compatible with every MIDI sound generator in existence, because all traditional MIDI keyboards send over a single MIDI channel. Click here to learn about LinnStrument's Smart MIDI, which prevents conflicts over a single MIDI channel when playing simultaneous pitch slides or Y-axis movements.

For best compatibility with standard one-channel (not MPE) synths and their preset sounds, which are optimized for traditional MIDI keyboards, use these settings:

MIDI Mode: One Channel
Main Channel: 1
Bend Range: 2
Timbre/Y: CC74
Loudness/Z: Poly Pressure

2) ChPerNote (Channel Per Note, also called MPE for MIDI Polyphonic Expression)
Each touch is sent on its own unique MIDI channel, permitting independent 3D control for each simultaneous touch. Played notes are rotated through the assigned Per-Note Channels (see "MIDI Channels" below). Messages common to all notes (like Program Change, Sustain/CC64 or Volume/CC7) are sent over the Main channel (See "MIDI Channels" below).

Hidden Setting: Force MPE Settings
Hold this button for more than 1/2 second to instantly change other relevant Per-Split Settings for MPE compatibility, for example to play our sounds file for Logic or MainStage. The button's light will turn light blue and these settings will be set as follows:

Left split: Main Ch 1, Per-Note Chs 2-8
Right split: Main Ch 16, Per-Note Chs 9-15
Bend Range: 24
Timbre/Y: CC74
Loudness/Z: Chan Pres

3) ChPerRow (Channel Per Row)
Each row’s touches are sent on a unique MIDI channel. By default, the lowest row is sent over channel 1, the next over channel 2 and the highest row over channel 8. Messages common to all notes (like Program Change, Sustain/CC64 or Volume/CC7) are sent over the Main channel (See "MIDI Channels" below).

Hidden Setting: Reverse Row Order
Normally the lowest row uses the lowest of the assigned 8 Per-Row Channels and the highest row uses the highest numbered channel. This can be a problem for some guitar synthesizers that always use channel 1 for the highest row/string. In such cases, hold the ChPerRow button to reverse the channel order so that the highest row uses the lowest of the 8 assigned channels and the lowest row uses the highest channel number. The button's light will change to the split's accent color.


MIDI Channels
(columns 2 - 6)

Columns 3 through 6 are used to select the MIDI channel(s) over which MIDI messages are sent. Depending on the selection in the View column (column 2), one of three MIDI channel assignments can be viewed or changed:

1) If VIEW is set to Main Chan (main channel), you can view or change the Main MIDI channel in columns 3 - 6. By default, LinnStrument uses channel 1 for the left split and channel 16 for the right split. If MIDI Mode is set to One Channel, then this setting determines the single channel over which all MIDI messages are sent. If MIDI Mode is set to Per-Note Channels or Per-Row Channels, then this setting determines the channel over which messages common to all touches (like Program Change, Sustain Pedal / CC64 or Volume / CC7) are sent.

2) If VIEW is set to PerNoteChs (Per-Note Channels), you can view or change in columns 3 - 6 which of the 16 MIDI channels are used for Per-Note messages. This is only useful if MIDI Mode is set to Channel Per Note. You can turn any of the channels on or off. By default, LinnStrument selects channels 2-8 for the left split and 9-15 for the right split.

3) IF VIEW is set to PerRowChs (Per-Row Channels), you can view or change in columns 3 - 6 which of the 16 MIDI channels are used for Per-Note messages. A contiguous block of 8 channels is always selected. To change the selection, select the lowest channel of the 8-channel continuous block you wish to use.

 


Bend Range
(column 7)

When you slide your finger left or right to perform pitch slides or bends, LinnStrument sends standard MIDI Pitch Bend messages. This setting determines the number of columns you must slide your finger left or right in order to send the minimum or maximum MIDI Pitch Bend value, equivalent to moving a MIDI keyboard's Bend Wheel fully forward or backward. For example, a setting of 12 means that sliding left or right 12 columns produces the maximum bend value. This should be set to the same Bend Range as in your synth. If set correctly, performing a pitch slide will finish on the same pitch as if you pressed the destination note pad directly. If not, this setting is wrong.

By default, LinnStrument's Bend Range is set to +/- 2 semitones, because nearly all standard preset sounds on common synthesizers use a bend range of 2 semitones. Though this provides compatibility with common sounds, it also prevents pitch slides over 2 columns. To increase the range/distance of pitch slides, set the Bend Range in both LinnStrument and your synthesizer to a higher value. A value of 24 is ideal for LinnStrument because it permits pitch slides of up to 2 octaves, which is the length of each row in the large LinnStrument model.

The options are +/- 2, 3, 12 or 24 semitones.

Hidden setting: Any Bend Range
To select any Bend Range from 1 to 96 semitones, hold the "+/-24" pad and the screen will display the current value in large numbers. Swipe left or right to adjust it from 1 to 96. If other than 24, its light in the Per-Split Settings screen will change to the split's accent color.

 


Pitch/X
(column 8)

Left-right movements (X axis) are always sent using MIDI Pitch Bend messages. The settings in this column are:

1) ON
If on, Pitch Bend messages are sent when you move your finger left or right, permitting smooth performance of vibrato or pitch slides.
If off, Pitch Bend messages are not sent, so pitch slides or vibratos cannot be performed. In this case, sliding left or right will play a series of consecutive semitone notes, as if gliding your finger up or down a piano keyboard or sliding up or down a guitar neck.

2) QUANTIZE
If on, striking a new note anywhere within the note pad will result in the same perfectly quantized semitone.
Then after you strike the note, moving your finger will produce unquantize pitch slides or vibratos. This is the equivalent of having frets when you strike the note but no frets (permitting vibrato or pitch slides) while holding the note after the initial strike.  This permits fast play in perfect tune, yet with the ability to perform expressive pitch gestures at any time.
If off, striking different locations within the pad will produce different pitches. For example, striking exactly between 2 note pads will produce a 1/4 tone that is exactly between the center pitches of the 2 note pads.

3) QUAN HOLD (Quantize Hold)
If on, pitch will be gradually corrected after a vibrato or pitch slide is finished. This permits you to stay in perfect tune while performing vibratos and pitch slides. This is especially useful when performing 2- or 3-part pitch slides on chords.

4) QHOLD FAST (Quantize Hold Fast)
Same as Quantize Hold but with a faster pitch correction after the vibrato or pitch slide is finished. This is useful for faster playing but may correct very slow vibratos or pitch slides.
For slower pitch correction, Press Quantize Hold + Qhold Fast together. This can be helpful when performing very slow vibratos or pitch slides because they will not be mistaken for the end of a pitch movement and mistakenly corrected.
For no Quantize Hold, turn off both Quantize Hold and QHold Fast.

Hidden setting: Reset On Release
Press the 5th pad from the top to turn on Reset On Release, which sends a Pitch Bend value of zero when a note is released. Normally this should be off to prevent pitch change upon release for sounds with long releases. However for sounds with fast releases, if you're hearing an occasional fast pitch sweep at the beginning of notes, it's because a previous note's bend value is remembered by the synth and is quickly being zeroed at the start of the new note. Turning this on will correct that.


Timbre/Y
(column 9)

These settings are related to forward/rearward finger movements, which are limited to the 17 mm depth of each note pad.

1) ON
If on, MIDI messages are sent in response to Y-axis finger movements.
If off, they are not.

Hidden setting: Timbre/Y High/Low Limits
Normally the value sent for Timbre/Y has a range of 0 to 127. However, you can change the low and high limits so that the sent values will be scaled between these limits. To change these range limits, hold the On pad and the screen will display large characters. Swipe up or down to switch between the following two settings, and left or right to edit each setting’s value:

"L 0": the Low Timbre/Y limit, from 0 to 127.
"H127": the High Timbre/Y limit, from 0 to 127.

If these settings are changed from their default values of L 0 and H127, the On pad in the Per-Split Settings screen will be lit in the accent color. Note that if the high limit is lower than the low limit, the output range will be inverted.

2) CC1
If selected, MIDI Control Change #1 messages will be sent in response to Y axis movements.

3) CC74
If selected, MIDI Control Change #74 messages will be sent in response to Y axis movements.

Hidden setting: Y Axis Message Select
Hold this button to select any CC number from 0 to 127, or Poly Pressure or Channel Pressure messages, for sending Y-axis information. The current assignment will be displayed in large characters. Slide left or right to adjust the CC number (0 to 127), followed by Poly Pressure and Channel Pressure. If Poly Pressure is selected, this permits polyphonic Y-axis data over a single MIDI channel. If a value other than CC74 is selected, the button will light in the split's accent color.

4) RELATIVE
If off, CC messages reflect absolute finger position within note cell.
If on, a CC value of 64 is sent at first regardless of the position of  touch, and subsequent Y-axis movements increase or decrease that value.

Hidden setting: Y-axis Relative Initial value
Hold to set the starting relative value from its default of 64 to any value from 0 to 127. For example, if using Y-axis to add a modulation amount, the Y-axis value at first touch will be zero, then moving your finger forward will increase the value.


Loudness/Z
(column 10)

These settings are related to the sending of MIDI data in response to varying pressure on the note pads.

1) ON
Enables sending of pressure (Z axis) messages. If off, no pressure messages will be sent.

Hidden settings: Loudness/Z Range Limits and High Resolution Pressure

Normally the value sent for pressure control has a range of 0 to 127. To change these range limits, hold this button and the screen will display large characters. Swipe up or down to switch between the following 3 settings, and left or right to edit each setting’s value:

"L 0"
This is the Low Loudness/Z limit, from 1 to 127. Normally this is set to 0.

"H127"
This is the High Loudness/Z limit, from 1 to 127. Normally this is set to 127.

Note that if the high limit is lower than the low limit, the output range will be inverted. Also, if these settings are changed from their default values of L 0 and H127, this button in the Per-Split Settings screen will be lit in the split's accent color.

"7 BT"
Normally pressure is sent as a 7-bit value from 0 to 127. Swipe right to send a 14-bit value as two CC messages. Then you must hold the “CC11” note pad and select a CC from 0 to 31. LSB data will be sent on the CC number that is 32 higher than the selected CC. For example, select CC11 to send MSB (Most Significant 7-bit Byte) on CC11 and LSB (Least Significant 7-bit Byte) on CC43.

2) POLY PRES (Polyphonic Pressure)
Send pressure data using Poly Pressure messages, also called Polyphonic Aftertouch.

3) CHAN PRES (Channel Pressure)
Send pressure data using Channel Pressure messages, also called Channel Aftertouch.

4) CC11
Send pressure data using Control Change 11 messages.

Hidden setting: CC Select
To change the CC number to something other than CC11, hold this pad and the current value will be displayed in large characters. Swipe left or right to change the CC number (0 to 127). If anything other than the default 11 is selected, the CC11 pad in the Per-Split Settings screen will change to the split's accent color

Note that either Poly Pressure, Channel Pressure or CC11 may be selected. You cannot select more than one.


Color
(column 11)

Select red, green, blue, cyan, magenta, yellow, white, orange, lime or pink for each of the following:

1) MAIN
By default, these are the note pads used to light all scale notes except C. The default color for the left split is green and for the right split is blue. Press this button to change the Main color, rotating through the 10 available colors.
Note that you can change the scale that is lit in Global Settings > Note Lights On/Off.

2) ACCENT
By default, these are the note pads used to light only the C notes within the scale. The default color for both splits is cyan (light blue). Press this button to change the Accent color, rotating through the 10 available colors.

3) PLAYED
When a note pad is touched (or a Note On message is received over MIDI), the note pad will change to the color selected here. Red is selected by default. Press this button to rotate though the 10 available colors or none.

Hidden setting: Light Animations
Hold to select one of a number of light animations that appear around the played note:

• Cell (Only the pressed note pad is lit. This is the default setting.)
• Same (When pressed, all note pads with the same pitch on other rows will light.)
• Crosses
• Circles
• Squares
• Diamonds
• Stars
• Sparkles (Roger's favorite, best in white)
• Curtains
• Blinds
• Targets
• Up
• Down
• Left
• Right
• Orbits

4) LOW ROW
This is the color of the Low Row when turned on. See the description of Low Row feature below.)


Low Row
(columns 12 and 13)

The lowest row can be changed to have a variety of alternate functions, conveniently operated by the thumb while the fingers are used to play notes on the other rows. The options are:

1) NORMAL
The Low Row feature is turned off and the lowest row is used for normal note play.

2) RESTRIKE
Striking the low row will restart all notes held in the upper 7 rows.

3) STRUM
Dragging your finger left and right across the Low Row will restart notes held directly above the current position on the Low Row, effectively strumming the notes above where you touch on the Low Row.

4) ARPEG (Arpeggiator)
Pressing the Low Row enables the Arpeggiator (at the selected Rate in Global Settings > Arpeggiator) for as long as you hold it.
Also, sliding your finger left or right from the initial position of touch will change the Arpeggiation rate between the 7 possible rates: 1/8 notes, 1/8 triplets, 1/16 notes, 1/16 half swing, 1/16 triplets, 1/32 notes and 1/32 triplets.

5) SUSTAIN
Pressing the Low Row acts as a momentary sustain pedal to sustain any held notes after release.

6) BEND
Pressing the Low Row and sliding left or right bends the pitch of all held notes. The bend range is set by the Bend Range parameter.

7) X=CC1
Pressing and sliding left/right on the Low Row acts like a continuous control strip, sending Control Change #1 messages.

Hidden settings: Low Row CC1 Mode and CC#
Hold the CC1 button to access two hidden settings. Swipe up or down to switch between the following two settings, and left or right to edit each setting’s value:

1) Hold/Fader select:
The 2 options are:
a) Hold Mode: Press anywhere on the Low Row to send an initial CC value of 0, then slide right (up to a distance of 7 pads) to increase the sent value up to 127, then release to send a zero value. This is the default mode, intended to use your thumb as a momentary sound change while your fingers are playing notes above.
b) Fader mode; In this mode, the Low Row acts like a long linear Mod Wheel control strip. Press the left end of the Low Row to send a CC value of 0, the right end to send 127, and anywhere between for a proportional value. The sent value remains after releasing the Low Row.

2) CC#
The options are 1 (default) though 127, followed by Channel Pressure. If other than 1 is selected, the “X=CC1” pad’s light in the Per-Split Settings screen will change to the Accent color.

8) XYZ=16-18
The low row acts as a three-dimensional control strip, sending CC16 from X axis movements, CC17 from Y-axis movements and CC18 from Z-axis movements.

Hidden setting: XYZ CC Assign
To change the CC number used for X, Y or Z and more, hold "XYZ=16-18" and the screen will display large characters. Swipe up or down to switch between the following four settings, and left or right to edit each setting’s value:

1) X-axis Hold/Fader select: Select “HLD” (Hold mode; press anywhere to send an X-axis CC value of 0, slide right up to 7 pads to increase the sent value to 127; release to send a zero value) or “FDR” (Fader mode; press to send an X-axis CC value of 0-127 proportional to your finger position that persists after release).

2) X CC#: Select CC for X axis (X1 - X127, Channel Pressure)

3) Y CC#: Select CC for Y axis (Y1 - Y127, Channel Pressure).

4) Z CC#: Select CC for Z axis (Z1 - Z127, Channel Pressure).

If any of the above CC numbers are not set to the default values, the “XYZ=16-18” pad (in the Per-Split Settings screen) will light in the accent color.


Special
(column 14)

Engages one (or none) of four special playing modes:

1) ARPEG (Arpeggiator)
Turn on to enable the Arpeggiator for this split, using the Arpeggiator settings in Global Settings.

2) CC FADERS
Changes the selected split into 8 horizontal sliders sending Control Change 1 through 8 messages over the Main channel.  Notice the CC1 through CC8 printing on the right edge of the playing surface. An example of using CC Faders would be to use the left split for normal play while using the right split to adjust 8 sound parameters in real time.

Hidden setting: CC Fader CC#
To change the CC number used for each fader, hold CC FADERS. The screen will display a large number and 8 blue lights on the right edge, one of which is lit in green to indicate which of the 8 faders is selected. Select one of these 8 lights to select a fader, then adjust its CC number from 0 to 127 (or select Channel Pressure) by swiping left or right. Note that these 8 assignments are unique for the left and right splits. Press Left Split or Right Split to view/edit the left or right split’s 8 assignments. If any value is changed from its default, the CC FADERS pad in the Per-Split Settings screen will be lit in the split's accent color.

3) STRUM
If on and Split is also on, you can strum this split to play any notes fingered on the split. For example, select STRUM in the right split, turn the SPLIT button on, then drag your finger forward and backward over the rows in the right split to "strum" any notes fingered in the same row of the left split, similar to strumming a guitar. As your strumming finger passes each row, the notes fingered in that same row on the other split will sound. Note the following:
a) When you finger a note in the opposite split, the note will not sound until you strum it in the Strum split.
b) If you strum a row that contains no touched notes in the other split, its lowest note pitch will play, similar to strumming open strings on a guitar.
c) If multiple notes are fingered in a single row, only the highest-pitch note will play.
d) Hammer-ons and pull-offs can be performed on each row.
e) Sensitivity of the Strum split is increased while Strum is on.

4) Sequencer
This enables LinnStrument's Step Sequencer. To learn about it, click the "Sequencer" tab at the top of this page.
