Melbourne Instruments Roto-Control

The motorised knobs are the reason to buy it and are praised almost everywhere: they jump to the current value when you switch track, plug-in or MIDI setup, follow automation, stop at a parameter's ends, click through stepped parameters and notch at centre for pan — quickly and nearly silently, with no wobble reviewers could find. The per-knob colour displays and the clicky mechanical-key buttons are liked too. The reservations: until June 2026 the displays showed names but not values, so reviewers kept glancing at the computer screen for things like EQ frequency; some owners find the centre indent too soft, or a knob a tick off-centre; and one reviewer argues that motors add less over plain endless encoders than they seem to when a screen already shows the value.

“They really are impressive and practically silent, too.”

Rory Dow · Sound On Sound

“The knobs on this thing are actually amazing.”

“Sadly, however, they don’t display values.”

Rory Dow · Sound On Sound

“The only small gripe for me here is that the indent (when enabled) feels too soft and a bit inconsistent.”

Mostly positive, with the grumbles concentrated in two places. In Ableton Live, MIX mode mirrors track names and colours, the knobs follow volume, pan and sends, and buttons handle mute, solo and arm; reviewers call it tight and intuitive, if not as deep as a Push. Bitwig support (from mid-2025) is often described as even smoother, since remote-control pages map automatically. PLUGIN mode uses a learn-once approach: you pick the parameters you care about and the controller recalls them for every instance of that plug-in — some reviewers prefer this to automatic mapping, others found the lack of auto-mapped devices and rack macros at launch a chore. Logic Pro support arrived only in February 2026: one early review got little out of Logic, and a Logic owner reports dropped connections. Outside the three supported DAWs it is a generic MIDI controller, which one Gig Performer user found glitchy with value feedback.

“It doesn’t manage the same level of detail, but it does the basics extremely well.”

Rory Dow · Sound On Sound

“I have a Push 3 but use the Roto more, it’s so useful for mixing and really intuitive to use, feels so tightly integrated.”

“Roto control does not automap device parameters at least not in the current firmware”

“Frequently stops communicating and requires complete reboot to recognise again.”

Sources split: one camp points to a firmware that has grown fast — Bitwig, Logic and Max support, group tracks, MIDI notes and program changes, value display and meters in eighteen months — and to support that answered quickly and replaced faulty units without fuss. The other camp finds the Roto-Setup editor tedious and limited (no copy/paste, awkward stepped buttons, one mapping per plug-in), reports updates that removed features or overwrote stored plug-in maps, first-press bugs and a Windows firmware updater that wouldn't run, and describes support emails that went unanswered for weeks — or, in one long case, a replacement that took months. Experiences of support are genuinely bimodal rather than middling.

A strong list for the size — two USB-C ports and a full 5-pin DIN MIDI in, out and thru, so it can drive hardware synths without a computer, with incoming CCs moving the knobs. The caveats are power and routing. Several reviewers and owners found the motors or touch sensing unreliable on bus power and needed the supplied adapter (the maker's FAQ recommends it for touch problems), which means two cables; there is no power switch or sleep mode, so the screens stay lit until you unplug it. At launch the thru port couldn't act as a second output and MIDI arriving at the input wasn't merged through, and the controller doesn't send or receive SysEx.

“It’s also nice to see a full complement of 5‑pin DIN MIDI in, out and thru ports for direct hardware control.”

Rory Dow · Sound On Sound

“The motorized encoders need external power, so you can’t run this device solely from bus power on a weaker port.”

Will Vance · Magnetic Magazine

“There is one design choice they made I find annoying: the unit does not have a power switch or sleep mode.”

Consistently described as compact and desk-friendly — about the width of a 15-inch laptop, 715 g, slim enough to sit in front of a keyboard or under a laptop — and a carry bag is included. The only portability complaint is the second cable for the power adapter.

“Kompakte Größe, ideal für kleine Setups oder mobile Workflows”

Felix Klostermann · Bonedo ('compact size, ideal for small setups or mobile workflows')

“It doesn’t take too much room up either”

Andy Jones · MusicRadar

Sources split: most reviewers and a majority of owners describe a solid, weighty unit with wobble-free knobs and satisfyingly clunky mechanical keys — though opinions differ on whether the plastic-and-metal case feels premium. A persistent minority of owners, on Elektronauts, Reddit and Thomann, report knobs with uneven resistance, grinding or motor noise, knobs a tick off-centre, touch sensors firing on their own, a loud internal whirr or knobs spinning until unplugged — several on exchanged second units. The maker says a little motor noise in a quiet room is normal, and in 2026 added a registered 10-year warranty on the motorised knob assemblies.

Sources split, close to evenly: for one camp the price buys something no rival offers — motorised recall, haptics and per-knob screens in a compact box — and Sound On Sound calls it low-cost for what it does. For the other, roughly $400–450 is a lot for eight knobs and eight buttons, particularly given the quality-control reports, the time needed to build mappings and the 64-plug-in storage limit; Bonedo lists the high price as a con. Cheaper screened alternatives (Faderfox EC4) and pricier deeper ones (Electra One) come up as the comparison points.
