How to Update Your LinnStrument Software

• Download the LinnStrument Software Updater using the links below under "LinnStrument Software Version History'. If necessary, double-click on the LinnStrument Firmware folder to uncompress the file.

Mac users only:

• Download the ".dmg" installer file and double-click it to open the folder containing the Updater app.

Windows Users only: You will need to manually install the LinnStrument Updater's Driver for Windows:

• Navigate to the LinnStrument Firmware folder you just un-compressed, and open the LinnStrument Driver folder

• Double-click dpinst-x86.exe (for 32-bit Windows) or dpinst-x64.ex (for 64-bit Windows) to begin installing the LinnStrument Windows Driver for the updater.

• Follow the on-screen instructions for installing the LinnStrument Windows driver.

• Navigate to the LinnStrument Firmware folder.

• Disconnect other USB devices from your computer, then use a USB cable of 10 feet or less to connect your LinnStrument directly to your computer, not through a USB hub.

• On your LinnStrument, turn on 'Global Settings > Actions column > OS UPDATE'. (Briefly press it to turn the button's light on. Do not hold it.) You're now ready to update your LinnStrument. DON'T DISCONNECT POWER DURING THE UPDATE.

• Double-click the LinnStrument Updater app to open it.

• In the LinnStrument Updater app, Click 'Update Firmware' then 'Go Ahead'. (If the 'Update Firmware' button is not clickable, recheck the above steps.) Your LinnStrument is now being updated, which will take about 2.5 minutes.
(If you're having problems updating, search the
LinnStrument FAQ page for "LinnStrument will not accept an OS Update from the LinnStrument Updater app. What's wrong?")

To confirm that the update was successful, check your LinnStrument's version number as explained at the top of this page.



LinnStrument Software Version History

2.1.0 (May 5, 2017. Current version)


• Mac:  linnstrument-firmware-2.1.0-macosx.dmg

Windows: linnstrument-firmware-2.1.0-windows.zip


• New Feature: You can now turn on light animations that surround and emanate from the played note pads, responding to velocity and pressure. In Per-Split Settings > Color column, hold PLAYED. Swipe L/R to select one of the following options:

Cell (only lights pressed cell)
Same (lights notes of same pitch on other rows, as in previous software versions)
Sparkles (Roger's favorite, because its shorter duration is less distracting from the note lights. Try it in white.)


• New Feature: additional Panel/Foot Switch options have been added. In Global Settings > Assign Switch, hold Tap Tempo then swiping L/R to select one of the following options, independent for the 4 switches:

TAP: Tap Tempo.
LEG: Legato. While switch is on, notes or chords are sustained after release until the next note or chord is played.
LAT: Arpeggiator latch. While switch is on, each pressed & released note will be added to the arpeggiated chord.
PR+: Preset +. The Preset number shown in Preset screen is incremented.
PR-: Preset -. The Preset number shown 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.

• New Feature: added support for negative row offsets and inverted guitar tuning.
In Global Settings > Row Offset columns, you could previously hold OCTAVE then swipe L/R to select any row offset from 0 to 16. Now the options include -16 to -1 and -GUI (inverted GUItar tuning).

• New Feature: Mirrored split pitch direction. Previously, turning on Left-Handed Mode (Global Settings > Column 1, 4th note pad from bottom) would reverse the pitch direction (R to L instead of L to R). Now you can reverse the pitch direction for one split only, permitting mirrored split tunings.
In Global Settings > column 1 > hold the 4th note pad from the bottom and Swipe L/R to select one of 3 options:
1) REV: reverse pitch direction of both splits (same as previous versions).
2) REVL: reverse pitch direction of left split only.
3) REVR: reverse pitch direction of right split only.
Note that you must turn on the note pad (col 1, row 4) for the selected pitch reversal to be on.

• New Feature: The Step Sequencer now responds to MIDI Song Position Pointer messages, thereby maintaining correct sync position if the external DAW is started from a position in the song other than the start.

• New Feature: in Assign Switches, permit SUSTAIN and CC65 to be reassigned to any CC, and independently for the 4 switches.
In Global Settings > Assign Switch columns, hold SUSTAIN or CC65. Swipe L/R to select option.

• New Feature: For Low Row's CC1 and XYZ=16-18 options, as well as for the CC Fader options, you can now select Channel Pressure in addition to the CCs 0-127.
In Per-Split Settings > Low Row columns, hold either CC1 or XYZ=16-18, then swipe all the way to the right.
In Per-Split Settings > Special column, hold either CC FADERS, then swipe all the way to the right.

• New Feature: added support for a configurable start value for the CC value sent when Per-Split Settings > Timbre/Y column > Relative is turned on. Previously it was always 64. Now it can be any value from 0 to 127. For example, if using Y-axis to add a modulation amount, this now permits the value at first press to be zero, then increased by tilting your finger forward.
In Per-Split Settings > Timbre/Y column, hold Relative. Swipe L/R to adjust value.

• New Feature: Channel Per Row mode's channel order can now be reversed, permitting for example the highest row to send on channel one and lowest on channel 8. This is useful when using some guitar synthesizers that prefer the high E string to use channel 1 and the low E string to use channel 6.
In Per-Split Settings > MIDI Mode column, hold ChPerRow. It will light in the accent color to indicate reversed channel order.

• New Feature: Previously, if the Arpeggiator was on and LinnStrument was synced to an external source, the Global Settings button would blink 1/4 notes. Now it also blinks if Arpeggiator is on and using internal tempo. This helps by showing you the Arpeggiator tempo before you start playing.

• Improvement: Previously if using One Channel mode and you played two note pads of the same pitch, releasing one of them would terminate both notes, because MIDI only permits one note of the same pitch per channel. Now the heard note is terminated only after releasing both note pads.

• Improvement: When synced to external MIDI clock, LinnStrument no longer also sends MIDI click. This prevents MIDI clock loops with external DAWs.

• Improvement: Incoming MIDI handling and response to external MIDI clock are now more reliable.

• Improvement: The 4 All-Settings Presets (on the right side of the Preset screen) now store and recall the status of the Split button, as well as which split is current selected.

• Improvement: When changing the MIDI Mode (in Per-Split settings), zero values are sent for the X, Y and Z messages, thereby preventing the external synth from adding the last-sent One Channel and Channel Per Note values.

• Improvement: the fourth/highest "All Settings" preset (on the right side of the Preset screen) is now configured by default for playing auto drumbeats on the left split and auto bass lines on the right split, as shown in the LinnStrument Introduction video at 4:36.

• Improvement: the entered tempo value is now saved after disconnecting and reconnecting power.

• Bug Fix: A rare bug existed in version 2.0.0 and later that causes the upper 2 note pads in columns 4 and 5 to stop working. This was due to a bug that caused the calibration values for these pads to be corrupted. We believe we fixed the cause of the bug but in case it happens in future and you notice that these 4 notes pads aren't working, simply remove and reconnect power to make them work again.

• Bug fix: the sequencer's Event Edit sliders (lower right of sequencer screen) would sometimes not return from the numeric display when a touch was released. Now fixed.

• Bug Fix: Previously, there were small inconsistencies in quantized pitch bend ranges. This is now corrected.

• Bug Fix: Previously, if Split was on, and a panel switch was assigned to Arpeggiator, is was sometimes impossible to turn the Arpeggiator on/off using the panel switch. This is fixed.


2.0.2 (December 12, 2016)


• Mac:  linnstrument-firmware-2.0.2-macosx.dmg

Windows: linnstrument-firmware-2.0.2-windows.zip


• New setting "Touch Sensor Prescale" permits adjusting the touch sensitivity over a wide range to better fit your personal playing style, so that the 3 fixed settings (low, medium, high) will be more useful to you. In Global Settings, hold Calibration while pressing Pressure Sens > Medium. Swipe left or right to adjust from 50 (most force required to produce velocity/pressure value of 127) to 100 (least force required to produce velocity/pressure value of 127). This does not affect very light touches, which always respond to the lowest possible force. The default value for LinnStrument (large model) is 60 and for LinnStrument 128 is 75 (to produce the same touch sensitivity).

• Strum mode (Per-Split Settings > Special column > Strum) improved to be more guitar-like:
• Only highest note on row (string) is recognized
• Hammer-ons and pull-offs can now be performed
• Fingered notes do not sound until strummed.
• Strumming area is much more sensitive to touch

• New Sleep animation: Snow Falling on Christmas trees. In Global Settings, hold Sleep (column 15, row 3) and swipe right to show “XMS”. Then swipe down to set delay before sleep animation starts.

• Split on/off status is now remembered after power off/on. After changing Split status, press Per-Split Settings or Global Settings once to save it.

• Default USB MIDI data rate (hold Global Settings > USB) is slightly slower (235) to avoid overloading slower computers or synths.

• Bug fix: Sometimes when syncing the Sequencer or Arpeggiator to external MIDI clock, the internal tempo would jump to very fast setting. Fixed.



2.0.1 (November 6, 2016)


• Mac:  linnstrument-firmware-2.0.1-macosx.dmg

Windows: linnstrument-firmware-2.0.1-windows.zip


• Bug fix: Sometimes, pressing the bottom or top of a cell would not always send a Y-axis value at the start. This is fixed.

• Bug fix: If the pressure was very soft, Quantize Hold would sometimes not correct the pitch as it should. This is fixed.

• Bug fix: The lights of the control switches would sometimes be lit incorrectly when a sequencer is active. This is fixed.

• Bug fix: The new colors white, orange, lime and pink could not be set using over MIDI messages CC20-22. This is fixed.



2.0.0 (October 27, 2016)


• Mac:  linnstrument-firmware-2.0.0-macosx.dmg

Windows: linnstrument-firmware-2.0.0-windows.zip


• Feature: Added polyphonic step sequencer for each split. See new Sequencer tab in the Panel Settings page:
http://www.rogerlinndesign.com/ls-sequencer.html  (See top of page for information on panel labels with Sequencer parameters.)

• Improvement: Significantly better velocity response, range and consistency, tuned for piano play with PianoTeq.

• Feature: Release velocity now supported in Note Off messages. LinnStrument is now “5D” in ROLI-speak. :)

• Feature: Four new LED colors: white, orange, lime and pink. Note that for these four new colors, if you move your eyes quickly across the playing surface, you will briefly see the individual RGB colors that comprise the combined color.

• Feature: Support for 14-bit Loudness CC values. In Per-Split Settings > Loudness/Z column:
1) Hold “On” for large character display. Swipe down three times then swipe right to select “14 Bit”.
2) Hold “CC11” for large charger display. Select any 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 on CC11 and LSB on CC43.

• Feature: Added support for using the DIN MIDI OUT jack as a MIDI THRU jack. In Global Settngs > MIDI/POWER column ("MIDI I/O" on older units), 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.

• Feature: Tap tempo has been added as a new option in the Assign Switch options, located above Octave Up.

• Improvement: Before when a note was played with Quantize on, the tuning would slide to the quantized pitch on initial touch. It now immediately jumps to the quantized pitch.

• Improvement: Removed occasional flicker when switching between LED displays.

• Improvement: The timing of send USB MIDI messages has been optimized so that slower hardware synthesizers are less likely to misinterpret some of LinnStrument’s sent MIDI messages.

• Improvement: The last-loaded "All Settings" preset is now remembered after rebooting.

• Bug fix: If a MIDI "Pitch Bend Sensitivity” RPN message was received, LinnStrument responded by setting the Bend Range incorrectly. Fixed.

• Bug fix: Updater application would sometimes not work correctly on Windows and MacOS Sierra. Fixed.

• Bug fix: The data sent through updater application could be corrupted with slower computers or certain USB connections. Fixed.



1.2.5 (June 9, 2016)


• Mac:  linnstrument-firmware-1.2.5-macosx.dmg

Windows: linnstrument-firmware-1.2.5-windows.zip


• Bug fix: some LEDs could sometimes flash brightly when exiting Per-Split Settings, Global Settings, and Octave/Transpose, and at the end of a OS update. Fixed.

• Bug fix: when a note was released, a MIDI pressure message of zero value was sent after the Note Off message. It should have been sent before the Note Off. Fixed.

• Bug fix: it is possible to start LinnStrument in Low Power mode by holding Octave/Transpose while connecting power, useful when first connecting to an iDevice. Previously, if Update OS mode was on when this was done, Update OS mode mode would not be automatically turned off. Fixed.

• Bug fix: sometimes a MIDI message could be sent with a slight time delay between its individual bytes, causing some receiving devices (particularly Linux systems) to misinterpret the first part of the message as incomplete. Fixed.

• Bug Fix: in low power mode, Polyphonic Pressure with a value of zero would not be sent. Fixed.

• Bug Fix: Switch 1 and Switch 2 would sometimes light after returning from sleep. Fixed.

• Bug Fix: if Sleep mode was set to enter sleep after a period of inactivity, it was possible to enter Sleep even while holding a note for a very long time because the delay timer didn't recognize Note Off messages. Fixed.

• Bug fix: when holding the Octave/Transpose switch to enable low power mode at startup, the Octave/Transpose page was shown instead of the normal Performance Mode lights. Fixed.
