A Comprehensive Master Controller

The Doepfer LMK4+ keyboard controller is ready to be the command center for your electronic music rig. Featuring 88 piano-style keys with hammer mechanics, and packed into a rugged flight case with removable lid, the LMK4+ is designed for maximum playability and portability. You have two MIDI outputs plus a USB MIDI output for controlling your gear, plus a MIDI input for working with a second keyboard or bass pedal. Complete with 128 memory slots to save your custom configurations, the Doepfer LMK4+ MIDI controller offers everything you need for masterful control over your synthesizers.

Comprehensive MIDI control

With the Doepfer LMK4+ controller keyboard, you'll be able to send MIDI program change and program bank messages, MIDI Start, Stop, Continue, and Clock, and all notes off (panic). In addition, the wheels, sliders, aftertouch, rotary control, pedals, and footswitch can all be assigned to any MIDI control parameter.

Exceptional playability and customization

You can fine-tune the feel of the LMK4+ keyboard controller to suit your playing style, with 32 selectable velocity response curves and 8 aftertouch response curves. The LMK4+ supports eight overlapping keyboard zones that you can assign as you wish, providing comprehensive control over multiple synths. Each zone can be assigned its own velocity and aftertouch curves, MIDI channel, MIDI output, transposition, controller activity, program change and bank number, and more.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:

2-year Total Confidence Coverage Warranty™!
Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!

In love!
One of the reasons I wanted one was because of influence, Hans Z, Junkie XL, and few others. I came here knowing that it was going be shipped from Germany, so theres a little waiting game from a few weeks, all depends on delays. Worth the wait since its represented by Sweetwater and they are highly responsible.

A few fundamentals to go with. Get a VFP1 or 2, I am actually waiting on more info to see if the the studioloigc pedal is the same as Doepfers, if not, I will have to place an order for the Doepfer double pedal. Luckily my nektar pedal has a switch where I was able to switch it, and it worked well. Also, get the power adapter SW offers, the LMK 4 doesn't power with the USB, I recommend you getting it if you're from the USA. The settings for sustain pedal and everything else is off so every time you turn it on you'll have to manually turn them on via the settings. Manual is pretty easy to read.

This masterpiece looks beautiful in any setup and any pianist will feel motivated to play. Feels great and I am happy with this product.

Es un gran Teclado MIDI. La sensación de las teclas es muy buena. Es un controlador resistente, hecho para durar, su configuración es intuitiva, es muy paramétrico y fácil de usar. Funciona correctamente con MAC y WIN y se acopla muy fácilmente a tu SET actual. Viene sin el adaptador de corriente, pero es sencillo construir una (punta XLR de Micrófono acoplada a un adaptador de corriente de 9V DC de 500mA).

He usado diferentes VST de piano, como Keyscape, The Grandeur, Ivory Pianos. Una Corda, Alicia Keys, Scarbee (Epianos) y todos funcionan muy bien.

Sin duda, recomiendo este controlador.

Muchas gracias a Will quien fue la persona que me estuvo ayudando en Sweetwater con la entrega y despacho. Todo fue excelente y según lo acordado.
