Alesis V49 MKII

The short version

What to know.

A 49-key USB MIDI keyboard controller, around $149 street, built to a deliberately narrow spec: full-size velocity-sensitive synth-action keys with no aftertouch, eight LED-backlit velocity-sensitive pads with Note Repeat and Full Level, four assignable 270° knobs, pitch and modulation wheels, a quarter-inch sustain jack and a USB-2.0 socket that carries both power and MIDI — no faders, no transport buttons, no display, no 5-pin MIDI out. Sources agree closely on four things: it is class-compliant and works the moment you plug it in, on Mac and on Windows, with no driver to install; the MKII layout is a real improvement on the original's left-hand cluster; the arpeggiator is unusually deep for the price, with six modes, tap tempo, eight time divisions, gate, four swing settings, latch and external clock sync; and it is light enough at 6.1 lb to travel on one cable. Opinion splits on three axes. The keybed: three magazine hands-ons describe a springy, responsive action that is the best part of the keyboard, while a steady minority of owners report the opposite failure — keys that read almost nothing until hit hard, with no way to change the response on the unit itself. The build: reviewers call the chassis sturdy and substantial for the money, some owners call it noisy plastic. And the software bundle, which is generous on the box and awkward in practice. The control set is minimal by design, and that is the one thing nobody disputes — only whether it is a virtue.

About this product

The second-generation V49, announced October 2021. The MKII moved the pads, knobs and function buttons from the left-hand side to the centre above the keys, enlarged the pitch and mod wheels, and replaced the original's four freely assignable buttons with fixed Arpeggiator, Note Repeat, Full Level and Tap Tempo controls. Not the 2014 V49, which bundled Ableton Live Lite 9 and Xpand!2 rather than MPC Beats. The V25 MKII (25 keys) and V61 MKII (61 keys) are the same instrument in other sizes; the Alesis Q-series are a separate, plainer line with no pads or knobs.

Alesis redrew its V range in October 2021, and the change was structural rather than cosmetic: the pads, knobs and function buttons that used to sit in a column down the left-hand side moved up to the centre, above the keys. Sound On Sound called that the biggest difference in the range, and it is what makes the MKII a different keyboard to play than the 2014 original — you no longer cross your left hand over the keybed to reach a pad.

What arrived with the redesign is a very specific proposition: 49 full-size velocity-sensitive synth-action keys, eight backlit pads, four knobs, two wheels, a sustain jack, a USB socket and nothing else. No faders, no transport, no screen, no 5-pin MIDI. Reviewers liked it and owners mostly agree — but the two things you can only judge with your hands on it, the keybed and the chassis, are exactly where the agreement stops.

A good fit for

  • First-time producers who want four octaves of full-size keys plus pads for around $149
  • Anyone who wants a controller that works in any DAW with no drivers, scripts or proprietary software
  • Players who want a properly deep arpeggiator on a cheap keyboard — latch, swing, gate and external sync included
  • Sketching beats where eight pads with Note Repeat and Full Level is enough

Think twice if

  • You have a piano background or care a lot about touch — this is the axis people argue about most, and there is no way to retune the response on the unit itself
  • You want faders, transport buttons, a display, or more than four knobs; several rivals add them for a little more
  • You need to drive hardware synths or drum machines — there is no 5-pin MIDI out, only USB
  • You expect DAW auto-mapping or a Mackie Control mode; this is generic MIDI you map yourself
  • You are on Windows and want the editor to be a supported part of the package rather than a work in progress

Common ground6

  • Class-compliant and driver-free — plug in the USB cable, select it in the DAW, play
  • Full-size synth-action keys are the point of the thing at this price, where most rivals go mini
  • The MKII layout, with pads and knobs above the keys rather than down the left side, is a real improvement on the original

Points of contention3

  • The keybed reads as springy and responsive to reviewers and as barely responsive until struck hard to a persistent minority of owners
  • The chassis reads as sturdy and substantial or as noisy plastic, with no middle position
  • The software bundle is generous as listed and awkward as delivered — the editor is registration-gated, unsupported on Windows 11, and MPC Beats has its own problems

Band: opinion spread · Dot: weighted average

The headline disagreement, and it is not about taste so much as about two different experiences of the same keyboard. Every magazine that put hands on one describes a springy, responsive full-size action and treats it as the reason to buy — Produce Like A Pro calls it where the V49 MKII shines. Against that sits a smaller but consistent group of owners reporting a specific failure: the keys register almost nothing unless struck hard, with no in-between. Nobody claims the action feels premium, there is no aftertouch on any V MKII, and — unlike several rivals at the price — there is no way to change the velocity curve on the unit itself.

Measured

Alesis specs 49 full-size velocity-sensitive synth-action keys — Sound On Sound describes them as 'waterfall' keys — with no aftertouch, and the user guide documents no on-board velocity-curve control: the only listed way to retune key response is the free downloadable V49 MKII Editor.

vs. listeners — That software-only adjustment is what both camps talk past. A response that reads as 'lively' to one player and 'super quiet' to another may be the same default curve landing differently, and on many rival boards you would simply change it with a key combination. Here you cannot: the editor is the only route, it is delivered through a registered Alesis account rather than the box, and Alesis's own Windows 11 compatibility table still lists the V MKII Editor as 'In Testing' while listing the hardware itself as Supported. So an owner who finds the curve wrong may have no fix at all on their machine.

What to keep in mind 6

  1. This is a read of where opinion sits as of September 2026. The MKII arrived in October 2021 and has not changed since, so the impressions have had years to settle — but the $150 controller bracket is the most crowded in music gear and rivals keep moving the goalposts.

  2. The keybed is the most personal part of this keyboard and the part sources disagree about most. If you can put your hands on one before buying, do — ten minutes of playing settles it faster than any review.
