DL4 MkII 1.10 Release Notes

DL4 MkII 1.10 Release Notes

DL4 MkII 1.10 (released 8. October 2024) includes important bug fixes, and is recommended for all users of DL4 MkII and DL4 MkII 25th Anniversary Limited Edition.

 
NEW FEATURES
New Global Setting—Tap Pitch
With certain delay types, adjusting delay time via Tap Tempo generates cool pitch artifacts; this behavior is accurate to the original gear. However, you can now set DL4 MkII to minimize these artifacts for more transparent tempo changes:

1. Hold ALT/LEGACY and press TAP to enter Global Settings.
2. Turn the model encoder to PITCH ECHO.
3. Press ALT/LEGACY to select the desired setting:
   • Authentic (Red, default)—Pitch artifacts are heard during tempo changes, such as heard on vintage tape and mechanical echo machines
   • Transparent (White)—Tempo changes are more transparent and pitch artifacts are minimized
4. Press any footswitch to exit Global Settings.

 
New Global Setting—LED Ring Brightness
When a preset is bypassed, you may now choose whether the LED ring is dim or off:

1. Hold ALT/LEGACY and press TAP to enter Global Settings.
2. Turn the model encoder to GLITCH.
3. Press ALT/LEGACY to select the desired setting:
   • Off/Bright (Red)—The LED is off when bypassed and bright when enabled (This is the same as the original DL4)
   • Dim/Bright (White, default)—The LED is dim when bypassed and bright when enabled
4. Press any footswitch to exit Global Settings.

 
Euclidean Delay—16 Steps
Euclidean Delay now supports a 16-step (was 8-step) sequence for more flexibility, which is the same range as in Helix.

• REPEATS controls the overall number of repeats heard for the entire sequence. If you want to hear all fills in the sequence only once, set this to 0%
• TWEAK adjusts the number of total Steps (from 1 to 16) to be filled in by the TWEEZ KNOB
• TWEEZ adjusts Fill, which is the number of echoes heard within the number of selected steps

TIP: To more easily hear the results of your changes, try sustaining a chord while adjusting the TWEAK and TWEEZ knobs.
 
 CHANGES

• The MIDI CC4 (Preset Bypass) value ranges have been swapped to maintain consistency with other Line 6 pedals. Now values 0-63 bypass the preset and values 64-127 enable the preset (prior to 1.10, 0-63 would enable the preset and 64-127 would bypass the preset)
• The DL4 MkII Owner’s Manual has been updated to 1.10: [URL]
   

BUG FIXES

• With certain combinations of overdub, reverse, and 1/2-speed, loop playback can become fragmented—FIXED
• When using delay models with a shorter max delay time at a very slow tempo, the TAP LED may flash out of sync—FIXED
• In certain rare cases, an expression pedal assignment might swap min and max values—FIXED
• With Bypass Trails on and Dry Path set to Analog, dry signal may no longer be heard on Preset A—FIXED
• While in Looper mode, setting the simultaneous delay to a subdivision may reference 120 BPM instead of the current tempo—FIXED
• In rare cases with Glitch Delay, quickly turning the Time knob to minimum may cause the delay signal to disappear—FIXED
• MIDI OUT/THRU only passes thru MIDI messages on the DL4 MkII’s global MIDI channel—FIXED
• If Global Settings were accessed while the classic 4-switch Looper was active, the 1 Switch Looper could become inoperable—FIXED
• In rare cases, tempo may not be stored and recalled correctly with every preset—FIXED
• If DL4 MkII was bypassed via built-in footswitch, sending it a Loop Record MIDI message may not successfully record a loop—FIXED
• Other minor improvements and fixes
