Global Settings are settings that apply to both keyboard splits. These settings are printed in small rectangles below the playing surface. Hold or tap the Global Settings button to display or change any of these settings. (Hold for momentary, tap to toggle on/off.)
Each column contains up to 4 settings. The status of these settings is indicated by the lights in the four note pads directly above the printed settings.
Each of the Global Settings is explained below.
NOTE LIGHTS ON/OFF
While in Performance mode, the natural notes are lit in the Main color (green by default) and the C within each octave is lit in the Accent color (light blue by default). These settings permit you to change which notes within the octave are lit in the Main color, and which are lit in the Accent color.
For example, you may wish to light the notes of a scale other than the standard major scale.
The VIEW column has 2 options: Main and Accent:
If VIEW = Accent, the 12 settings at right (C through B) display the notes within each octave that are lit in the selected Split's Accent color. By default, only C is selected.
If VIEW = Main, the 12 settings at right (C through B) display the notes within each octave that are lit in the selected Split's Main color. By default, the natural notes (C, D, E, F, G, A and B) are selected. Press any of these 12 note pads in order to turn it on or off.
Left-Hand Mode (hidden setting).
If on, the pitch of each row increases in the right-to-left direction instead of the normal left-to-right direction.
Hold this button to alter its function to one of 3 options:
1) REV: reverse pitch direction of both splits.
2) REVL: reverse pitch direction of left split only, for mirrored outward-increasing pitch.
3) REVR: reverse pitch direction of right split only, for mirrored inward-increasing pitch.
Note Lights Presets (hidden setting)
If the 3rd row from the bottom is selected, the 12 settings at right (C through B) are used to select one of 12 presets, each containing a unique set of both Main and Accent light settings. This permits quickly changing the lights of one musical scale to another. Though all 12 presets are editable, the default contents are:
C: Major (default), C#: Natural minor, D: Harmonic minor, D#: Major Pentatonic, E: Minor Pentatonic, F: Major Blues, F#: Minor Blues, G: Diminished, G#: Whole Tone, A: Spanish (Phrygian Dominant), A#: Gypsy (Hungarian Minor), B: Arabic (Major Locrian).
Note that you can set any note pad's light to any color by sending LinnStrument a series of three MIDI Control Change messages:
1) CC20: Column number of note pad to change (control key column is 0, left play column is 1, right play column is 25)
2) CC21: Row number of note pad to change (bottom row is 0, top is 7)
3) CC22: Color to change it to (0=as set in Note Lights settings, 1=red, 2=yellow, 3=green, 4=cyan, 5=blue, 6=magenta, 7=off, 8=white, 9= orange, 10=lime and 11=pink).
First send CC20 and CC21 to select the column and row to be lit, then send CC22 to light it.
LinnStrumentalist Ben Fuhrman has created a Max patch--as well as standalone mac and windows apps-- that allow you to graphically set each of LInnStrument's note pads to any color. Click here to download it.
This setting determines the pitch offset between rows. The default setting is +5, so that the leftmost pitch of each row is 5 semitones higher that the leftmost pitch of the row below it, just like the 4 lower strings of a guitar. The options are:
+3 through +7 for an interval of 3 to 7 semitones between rows.
+OCTAVE for each row to be one octave higher than the row below.
To change this selection to any row offset from -16 to +16, hold +OCTAVE and the screen will display “12” in large letters. Swipe left or right to edit the value, including the leftmost value "-GUIT" (upside down guitar tuning). If set to any value other than the default 12, the +OCTAVE pad will light in light blue instead of the normal blue.
GUITAR for guitar tuning on the upper 6 rows + 2 extra bass strings below on the bottom, each tuned 5 semitones below the row above it.
NO OVERLAP for each row to continue at a pitch one higher than the end of the previous row.
Note: To select no offset (all rows start with the same pitch), press the lit selection to turn it off.
ASSIGN FOOT/PANEL SWITCHES
There are 2 foot switch inputs, plus two assignable switches to the left of the playing surface. To view or change the assigned function of any of these 4 switches:
1) In the SELECT SW column, select the switch to be viewed or changed. Its current assignment will be display in the ASSIGN SWITCH area.
2) To change the selected switch's assignment, press the desired assignment in the ASSIGN SWITCH area.
The assignment options are:
1) TAP TEMPO (directly above Octave Up) Tap 1/4 notes to set the tempo for the Arpeggiator and Step Sequencer.
Hold this button to change its function from TAP TEMPO to one of the following, selected by swiping left/right:
TAP: Tap Tempo (default).
LEG: Legato. While switch is on, notes or chords are sustained after release until the next note or chord is played.
LAT: Arpeggiator latch. If Arpeggiator is on then while switch is on, each pressed & released note will be added to the arpeggiated chord.
PR+: Preset +. The Preset in Preset screen is incremented.
PR-: Preset -. The Preset in Preset screen is decremented.
PCH: Pitch slide on/off. Reverses the selected state of Per-Split Settings > Pitch/X column > On. This is useful, for example, to quickly switch between smooth pitch slides and semitone slides as on a guitar.
Plus the following 3 only for the Foot switches:
PLAY: Start or Stop the internal step sequencer. This can also be controlled by MIDI NRPN messages.
PREV: Previous Sequence, of the 4 sequences in the Step Sequencer. This can also be controlled by MIDI NRPN messages.
NEXT: Next Sequence, of the 4 sequences in the Step Sequencer. This can also be controlled by MIDI NRPN messages.
2) OCTAVE DOWN and OCTAVE UP
3) SUSTAIN (CC64)
To change the control change number sent, hold then swipe left or right to change the displayed value. If set to any value other than the default 64, the “SUSTAIN” pad will light in light blue instead of the normal blue.
To change the control change number sent, hold then swipe left or right to change the displayed value. If set to any value other than the default 65, the “CC65” pad will light in light blue instead of the normal blue.
5) ARPEGGIATOR on/off
6) ALT SPLIT: when Split mode is off, this alternates between the left and right split playing across the full playing surface.
Because the foot switch assignment is global, there is a single assignment, and that assignment applies to whichever split is selected, left or right. And if the Split button is on (split keyboard play), then the foot switch only affects the Selected Split. (The Selected Split is the split selected in the Per-Split Settings screen, and is also indicated by the color of the Split button.) For example, if Split is on and the Left Split is the Selected Split, the sustain pedal will only sustain notes on the Left Split.
However, if BOTH SPLITS is on, then when the Split button is on (split keyboard play), the foot switch will affect both splits. For example, if Split is on, the sustain pedal will sustain notes on both the Left and Right Splits.
Velocity & Pressure Sensitivity
FIXED: Regardless of how hard or soft you play, a velocity value of 96 is always sent.
Fixed Velocity Value (Hidden Setting)
Hold the Fixed Velocity pad to adjust the fixed velocity value that is sent by swiping left or right. Default is 96.
Low (for players with a heavy touch)
High (for players with a light touch)
Low and High Velocity Limits (Hidden Setting)
Hold either Low, Medium or High to access the Low and High Velocity limits, shown in large characters. All velocities played will be scaled between these two values. Swipe up to view the Low Velocity Limit (L1 by default) or swipe down for the High Velocity Limit (H127 by default). Swipe left of right to adjust the displayed value.
Aftertouch: If on, LinnStrument's sent pressure messages behave like the traditional Aftertouch on MIDI keyboards: they only exceed zero once you've pressed the note pad approximately 80% of its normal finger pressure range. If off, it behaves as normal with pressure values exceeding zero with a very light touch.
Low (for players with a heavy touch)
Touch Sensor Prescale (Hidden Setting)
This setting scales the raw output of LinnStrument's touch sensor before pressure and velocity processing, so that the Low, Medium and High Sensitivity settings for both Velocity and Pressure will be optimized to your unit's touch sensor, but can also be used to fine-tune the touch sensitivity to your personal playing style. This setting is calibrated at the factory in LinnStrument units from 888 up, and LinnStrument 128 units from 122 up, so you should not need to change it. If it shows a value of 100, it has not been calibrated and we suggest changing it to 60 for LinnStrument or 75 for LinnStrument 128.
To change the setting, hold Calibration (col 16, row 4) while pressing this button to see a number in large digits. If it doesn't show "100", write it down because that's the factory-calibrated value, and you may wish to return to it. The displayed value can be changed from 50 to 100 by swiping left or right on the lowest row only. 100 = highest sensitivity, requiring only a medium pressure or strike force to produce high output pressure or velocity values close to 127. 50 = lowest sensitivity, requiring a much harder pressure or strike force to produce high output pressure or velocity values. Very light touches are unaffected by this setting. Note also that the lowest row acts as a pressure meter when you press any of the note pads in the upper 7 rows, visually indicating the output MIDI pressure value (0-127) for how hard you are pressing.
The upper right note pad appears in light blue and is used for calibrating the displayed value. If you wish to try calibrating it to your personal style, first write down the calibrated value so you can set it back if you want. Now hold a note pad in the center area with a pressure level that you feel is appropriate in your playing style to produce the maximum output MIDI pressure value of 127, then also press the upper right note pad with your other hand. The displayed value with change to a value that will produce MIDI pressure of 127 at the pressure you were holding. At the factory, this value is calibrated by placing a 500 gram weight with an 11mm diameter rubber foot on the center of the note pad at column 9 (from left) and row 5 (from bottom), then pressing the upper right note pad. This results in a value of approximately 60 for LinnStrument and 75 for LinnStrument 128.
High (for players with a light touch)
LinnStrument's Arpeggiator works similarly to arpeggiators in MIDI keyboards, arpeggiating the individual notes of a held chord in various ways.
To use the Arpeggiator, set these settings as desired, then turn the Arpeggiator on in the desired Split (left or right) in the Per-Split Settings / Special column. You may also assign the Low Row (in Per-Split Settings) or the Foot or Panel Switches (in Global Settings) to momentarily turn the Arpeggiator on or off. The settings are:
REPLAY ALL, RANDOM, UP or DOWN:
UP arpeggiates in the upward direction though the held chord, DOWN arpeggiates in a downward direction and RANDOM picks notes randomly. Hold UP and DOWN simultaneously to select UP & DOWN. Select REPLAY ALL to restrike the entire held chord. In each case, vary the pressure of the held chord to vary the velocity of the arpeggiated notes.
1/32, 1/16, 1/8 and TRIPLETS:
Select the Arpeggiator rate (1/8, 1/16 or 1/32 notes) relative to the tempo. Select Triplets for 1/8, 1/16 or 1/32 note triplets. Hold 1/8 and 1/16 simultaneously to select SWING for swing-time 1/16 notes. This swing timing is exactly halfway between no swing and full triplet swing, providing a more human swing feel.
TAP TEMPO: The light will flash 1/4 notes at the current tempo. Tap 1/4 notes here to change the tempo for both the Arpeggiator and the Step Sequencer. When pressed, the numeric tempo will be displayed in the upper half of the screen, which you can change by sliding your finger left or right over the displayed number.
+1, +2 OCTAVES:
Select whether to add none, one or two upper octaves to the arpeggiated notes.
Note: If MIDI Clock is being received, the Arpeggiator and Step Sequencer will sync to received tempo and Song Position Pointer. LinnStrument will send MIDI Clock only if not also receiving MIDI Clock, in order to avoid a MIDI Clock feedback loop in your DAW.
("MIDI I/O" in older models)
The two lower choices are used to select whether to send and receive MIDI over the MIDI jacks or USB. By default, USB is selected, which is 3.7 times faster than the MIDI jacks.
Note also that if UPDATE OS (explained below) is ON, no MIDI data will be sent over USB.
If USB is selected, your computer should show "LinnStrument MIDI" as the name of the MIDI device.
MIDI Thru (hidden setting)
Hold “MIDI JACKS”. Swipe right to select “THRU”. Now the DIN MIDI OUT jack will both send MIDI OUT data and also echo received MIDI IN data.
USB MIDI Data Reduction (hidden setting)
If LinnStrument's high volume of MIDI data sent over USB is overloading your computer or sound generator, you can slow down the transmission rate of MIDI messages. Hold MIDI I/O to view the delay time (in microseconds) that is added between sent MIDI bytes. Swipe left or right to change the value. Default is 235. As a point of reference, a value of 300 slows it down to the speed of the MIDI jacks, and a value of 600 slows it down to half the speed of the MIDI jacks.
Low Power mode:
If ON, LinnStrument is placed in a special Low Power mode that permits it to be powered over USB from any Lightning-equipped iPad or iPhone. While on, the panel lights will be dimmed.
If OFF, LinnStrument is in normal full-power mode and the panel lights are full brightness.
When connecting an iDevice to LinnStrument for the first time, you can force LinnStrument to wake up in Low Power mode by holding the Octave/Transpose button while connecting power.
Press to enter Sleep mode. Pressing any note pad turns them back on. You can also enter Sleep mode by press Per-Split Settings and Global Settings simultaneously.
Hold this pad to adjust two Sleep parameters. Swipe up/down to select the parameter and left/right to edit its value:
1) Sleep display select:
“SLP”: all lights off. Note: you can immediately enter Sleep mode at any time by pressing Per-Split Settings and Global Settings together.
“STR”: a looping promotional animation, intended for stores.
"XMS": a looping Christmas animation with snow falling on Christmas trees.
2) Timer select:
“NOW”: Pressing Global Settings > Sleep immediately enters Sleep mode, or
“D1-D30”: The Global Settings > Sleep button is a toggle. If on, then after the selected number of minutes of Delay after not touching LinnStrument, Sleep mode is entered.
CALIBRATE: Your LinnStrument is calibrated for accurate X- and Y-axis precision at the factory and never needs recalibration. However, there may be circumstances where we ask you to perform a recalibration as demonstrated in this video. DO NOT do this unless we ask you to because it probably doesn't need it and you may do it incorrectly, resulting in less accuracy.
UPDATE OS: Select before receiving an OS update from the LinnStrument Firmware Updater.
NOTE: No MIDI data is sent while UPDATE OS is on.
OS VERS: Select to see the current OS version.
NOTES OFF: Select to turn off any stuck notes.
RESET: Press UPDATE OS and NOTES OFF together to reset all settings in LinnStrument (except Calibration) to factory status.
Hidden Settings: Scrolling Audience Messages
AUDIENCE MESSAGES: Pressing the note pads in column 1 through 16 of the top row causes one of 16 text messages to scroll across the screen. The text is upside down so that if you're holding your LinnStrument as a guitar, the messages will appear correctly for the audience to read.
To edit any of these messages:
1) Hold the button of the specific message to be edited for 2 seconds. This will enter Edit Mode.
2) Slide your finger up or down within a single column over a letter to change it, or slide your finger left or right within a single row to scroll other letters of the message onto the screen. The maximum message length is 30 characters.
3) When finished, exit Global Settings.
Note that your edits remain after powering off and on, as well as after an OS Update.
