Line 6 | DL4 MkII | Part Two - Secret Functions

This DL4 MkII tutorial shows some of the secret functions, including tap tempo subdivision, accessing/modifying the secret reverbs, morphing knob positions with an expression pedal, and customizing the global settings.
The DL4 Delay Modeler has remained one of the most widely used delay pedals in the world for more than two decades. The DL4 MkII includes all the sounds and features of the original, while introducing new sounds and features. The 15 new MkII delays were drawn from our HX® family of amp and effects processors and the 4-Switch and 1-Switch looper types offer up to 240 seconds of record time (expandable to several hours using an optional microSD card). There's an XLR microphone input, MIDI In and Out/Thru connectors, heavy duty footswitches, three bypass options, and a jack for connecting an optional expression pedal or two footswitches. The DL4 MkII is also smaller and lighter than the original, making it an even more appealing choice for modern musicians.
• Identical knob and footswitch layout as the original DL4
• 30 Delays: 15 MkII plus 15 Legacy DL4
• 2 Looper types-mono/stereo and pre/post signal path options
• Up to 240 seconds of looping time, or several hours with optional microSD card
• XLR dynamic microphone input for vocal processing and looping
• MIDI In, Out/Thru DIN connectors-receives PC and CC messages
• 128 Presets via MIDI, with footswitch control of up to six
• Switchable true, buffered, or DSP bypass
• Input for optional expression pedal or two additional footswitches

I’d appreciate a deep dive video on the MIDI features of the DL4 MkII.

[@filipdinevmusic]

amaaaaaaaazing, dl4 mkII should feature an app for customizing presets. :)

[@meinbherpieg4723]

This is the way.

[@MoreShowCyberstore]

Excellent Delay!

[@THE-CRT]

Mine makes a little buzz following the tap tempo when the delays are off, any reason why?

[@shellsjoint]

Excellent video!!

[@333baxter333]

You'll have to explain for us how to set parameters when using two footswitches at the same time

[@meinbherpieg4723]

This is great stuff. Where do I take the test to become a certified DL4 MKII technician?

[@addy_hits]

any chance on an in-depth midi function video? Suggestion for a firmware update: more midi integration with the Looper. Specifically I think it would be cool to have the loop length or play once controled by the midi clock so you coudl sync the DL4 MkII up to a drum machine/sample/sequencer. As far as I can tell the midi clock sync only really controls the delay time.

[@neilhawk]

midi integration with both looper modes would be awesome as a firmware update!

[@bunjumun]

does it do this yet? that's really a deal breaker for me on a loop pedal

[@Ebotronix]

I want to connect it to a Mixer FX Send / Return .I miss a Global dry kill switch !

[@tomastroia]

Hey, just bought the pedal, really good, but theres some thing i need help with: whenever i set the time subdivision for example for triplets and save the preset, once i press another preset and go back to the one i put triplets it returns to 1/4 sub division. May anyone help me? i really need this function to work

[@Guitar_Sounds]

Hi there the delay effects will not play through the looper when selecting it via foot switch 5 on my unit can you help? Cheers Anthony

[@AndrewStottisTheIndiWerWlf]

I cant get an MXR Tap to work. I have it in the FS5 mode and tried every option on the tap. Then I even tried just shorting the tip and sleve and nothing.

[@blueguitar1958]

Not yet available on Europe, is it?

[@FR-pp4qh]

is there a gated reverb in it ?

[@yoav282]

I’m trying to use the MK2 tap tempo without the time stretch effect whenever I’m changing the tempo. Like it was in the old DL4. Please help!

[@jackgilbert5914]

Did you ever sus this out? I’m having the same issue. It’s super annoying!!

[@yoav282]

​@@jackgilbert5914 Nope. i bought the old one again. MKII can't do that.

[@einsonwahyu1146]

really need to tap tempo with transparent audio... without pitch changing effect.

[@aperezdeal]

Can you run the reverb while the delay is off?

[@KettchGER]

Can anyone answer this? Am curious about this too.

[@addy_hits]

@@KettchGER short answer: Yeah, pretty much. The delay settings are independent of the reverb settings, so you can set the reverb however you want and the turn the delay time/repeats all the way to zero, effectively turning the delay off.

[@KettchGER]

@@addy_hits Thanks for the reply. So, if I wanted to replace my reverb-pedal with just the DL4 I could do the following?: Turn the delay-mix down and find myself a nice reverb-sound. -> Save as Preset A: Reverb only Dial some nice delay-sounds back in. -> Save as preset B, C, D, E, F (Delay + Reverb). Seems very usable for my live-rig. Think I will have to get myself a new pedal. 🙂

[@felipealonso8409]

New DL-4 killed my Quad Cortex…

[@jumpingman8160]

... it was a mistake

[@justincase4925]

I have no time to memorize the cheat sheet and 20 page Manuel. How about just clear bold names and fuctuin footswitches. Bpm led display. No guessing

[@tjancijr]

I'm officially too old for this pedal.

[@rcanderson4328]

What about the significant volume drop from the first DL4, is that fixed? Why not have a dedicated looper shortcut? As it sits, it’s still a “looper only” “delay only” style pedal… This is very sad to see.

[@Jamesjimjimmy]

Not true. You can use a simplified version of the looper with the delays. And the looper has always had delay capabilities anyways

[@DominiqueWillkins]

You can now set to looper, record something and go back to the delay mode with the looper playing in the back. Volume drop fixed, along with stomp switches. Massive improvement!

[@spacedusted999]

I had an old dl4 with a extra tap button that would do that! Other that… always use the xpression to control your loop volum as well as tweez or delay mix

[@boyan.guitar]

My B switch stopped working after only a few uses. How about you make a hidden feature where your stuff actually works for longer than five minutes? Or have customer support that actually works. I’m selling what few line6 things I have and never buying this amateur brand cr*p ever again.

[@fabronaut7478]

there's this thing you may have heard of called a warranty

[@iansmirna5183]

@@fabronaut7478 If something like a switch fails on me after a few uses, I won't use warranty either, that's a direct one way back to the seller. MK1 have actually a fair bit of a bad reputation concerning the quality of the hardware.

[@Supernautiloid]

I mean, it’s not really secret if you’re telling us about it. Just saying.
