Verdicts come from published specs and measurements, structured reading of owner reviews, and our own weekly price record. ## Short answer For most people the best midi interface is the CME U6MIDI Pro, $49.99 when we checked it on 2026-10-19. Two or three pieces of MIDI gear that need to route to each other, not just to a computer. - **Best on a budget:** Roland UM-ONE Mk2 ($46.99 on 2026-10-19). One synth or keyboard that just needs to reach a computer. - **Best for most people:** CME U6MIDI Pro ($49.99 on 2026-10-19). Two or three pieces of MIDI gear that need to route to each other, not just to a computer. - **Best if you want the most:** iConnectivity mioXM ($249 on 2026-10-19). A whole studio's MIDI gear, or a stage rig with several computers and instruments, routed through one hub. ## Overview A MIDI interface has one job: get 5-pin MIDI hardware talking to a computer, or to other MIDI hardware, without adding lag or dropouts. The three picks here sit on a straight port-count ladder, from one cable in and out, to three ports with routing, to a four-port network hub built for a whole studio. There is no single dominant Reddit thread behind this pick set. It comes from the manufacturers' own specs, Amazon owner-review counts and ratings as of August 2026, and where each product sits on mid1's price ladder for the category. What separated the picks: - Port count against the job, since one synth needs one port and a rack of gear needs a router - Class compliant versus driver installs, because plug-and-play only holds if the OS already knows the device - Where routing lives, on the box itself or buried in a software utility - Wired reliability over Bluetooth convenience, which trades a few milliseconds of latency for freedom from cables ## The picks compared | Pick | Tier | Price when we checked | Our rating | Best for | | --- | --- | --- | --- | --- | | [Roland UM-ONE Mk2 USB MIDI Interface](https://mid1.com/product/roland-um-one-mk2-b00967un50) | Budget Pick | $46.99 on 2026-10-19 | 7.8/10 | One synth or keyboard that just needs to reach a computer. | | [CME U6MIDI Pro 3-in-3-out MIDI Interface](https://mid1.com/product/cme-u6midi-pro-b0bffqgb33) | Best Value | $49.99 on 2026-10-19 | 8.6/10 | Two or three pieces of MIDI gear that need to route to each other, not just to a computer. | | [iConnectivity Interface with 4 in x 4 Out 5-pin DIN-MIDI Ports (mioXM)](https://mid1.com/product/iconnectivity-mioxm-b07y2rn1d4) | Premium Pick | $249 on 2026-10-19 | 9.1/10 | A whole studio's MIDI gear, or a stage rig with several computers and instruments, routed through one hub. | ## How to choose midi interfaces Start with how many pieces of MIDI gear need to reach the computer, then work outward. - Class compliant: the device needs no driver install, it just works when plugged in on macOS, Windows, iOS or Linux. Most current interfaces are class compliant, older or cheaper ones sometimes are not. - USB host vs USB device: a USB device interface only talks to a computer. A USB host port can power and read a class-compliant USB-MIDI controller directly, with no computer in the chain at all. - Merge and thru: thru repeats an incoming MIDI signal out to another device unchanged. Merge combines two incoming streams into one output, which is what lets two controllers play the same synth. - Latency: on a wired 5-pin or USB interface, latency is a non-issue, well under a millisecond in practice. It only becomes real over Bluetooth MIDI, where a few milliseconds are added by the wireless link itself. - Bluetooth MIDI: adapters like the WIDI Master trade a small amount of latency for no cables at all, useful on stage or with a keytar, less useful in a fixed studio where a cable was never the problem. Buy for the number of ports you will actually fill, not the number printed on the biggest box. ## Our take The CME U6MIDI Pro is the default pick. Most home studios land on two or three pieces of MIDI gear sooner or later, a keyboard plus a drum machine or a second controller, and the U6MIDI Pro is the cheapest box that routes between them instead of just passing one cable through. 3 in / 3 out over a single USB-C port covers that rig with room to grow into it. The Roland UM-ONE Mk2 is the right call for one instrument and nothing else, a simple one-cable interface that does the one job it has cleanly. The iConnectivity mioXM is for a studio built around routing itself, several synths, a couple of computers, maybe a stage rig, where the Ethernet networking and four USB host ports earn their price. For a lighter routing job than the mioXM but heavier than a single cable, the iConnectivity mio in our catalog covers one USB-MIDI connection at a lower price than either the UM-ONE or the U6MIDI Pro, and the CME WIDI Master, CME WIDI Jack and Yamaha UD-BT01 cover the wireless route for anyone who wants to lose the cable rather than add a router. The Kenton THRU-5 is worth knowing about too, a dedicated 1-in, 5-thru box for anyone who needs to fan one clock or controller out to a rack of synths rather than route between a handful of them. Basis: no single dominant Reddit thread drove this pick set. Specs are the manufacturers' own, owner review counts and star ratings are pulled from Amazon as of August 2026, and picks are placed on the price ladder from budget to premium. Ratings score each interface on the merits with price left out, so the premium pick sits highest and the tier label only tells you where it sits on price. We track listings and prices; we have not hands-on tested these. ## Full breakdown ### Budget Pick: Roland UM-ONE Mk2 USB MIDI Interface Our rating: 7.8 out of 10. Best for: One synth or keyboard that just needs to reach a computer. The Roland UM-ONE Mk2 is the one-cable answer to a simple problem: one piece of 5-pin MIDI hardware talking to a computer. Roland has made a version of this same one-cable interface for years, and this is that idea shrunk down to 1 in / 1 out and nothing else. FPT processing, Roland's low-latency circuitry, keeps clock timing tight enough for a drum machine or arpeggiator locked to a DAW. It runs on USB bus power with no separate adapter, works with Mac, Windows and iPad via Apple's Camera Connection Kit, and the USB and MIDI cables are built into the unit rather than sold apart. The tradeoff is in the name: one port each way, no merge, no thru, nothing to configure because there is nothing to configure. For a single synth it is the right amount of interface. For a rig with three or four pieces of MIDI gear, it is the first cable you outgrow. **What we like** - 1 in / 1 out with the USB and MIDI cables built into the unit - FPT processing keeps latency low and clock timing tight - Works with Mac, Windows and iPad via Apple's Camera Connection Kit - USB bus powered, no separate adapter to carry **Watch outs** - Only one MIDI in and one MIDI out, no merge or thru - No routing or filtering, it only passes MIDI straight through - Becomes a bottleneck the moment a second device joins the rig - Ports: 1 in / 1 out - Connectivity: USB MIDI cable interface, built-in USB and MIDI cables - Compatibility: Mac, Windows, iPad via Apple Camera Connection Kit - Power: USB bus powered - Processing: FPT for low latency and clock timing - Weight: 3.2 ounces - Dimensions: 1.2" x 2.4" x 0.6" Product page: https://mid1.com/product/roland-um-one-mk2-b00967un50 ### Best Value: CME U6MIDI Pro 3-in-3-out MIDI Interface (Editor's Choice) Our rating: 8.6 out of 10. Best for: Two or three pieces of MIDI gear that need to route to each other, not just to a computer. The CME U6MIDI Pro is what you reach for once one MIDI cable stops being enough. It packs 3 in / 3 out of 5-pin routing behind a single USB-C port, built as a standalone router rather than a plain pass-through interface. Split, thru, merge and filtering are configured through CME's free UxMIDI Tools software for Mac and Windows, and the box passes MPE, sysex, MIDI timecode and clock alongside ordinary notes and controllers, so it holds up behind synths and controllers that lean on those messages. A high-speed optocoupler keeps the signal clean between ports. The catch is that the configuration lives entirely in software, so there is nothing to see or adjust on the box itself once it is set. Three ports is also a ceiling, fine for a small rig, tight the moment a fourth piece of gear shows up. It has a shorter Amazon track record than the budget pick, with under a thousand reviews so far. **What we like** - 3 in / 3 out routing over a single USB-C cable - Free UxMIDI Tools software configures split, thru, merge and filtering - Supports MPE, sysex and MIDI timecode alongside standard notes and CC - High-speed optocoupler for clean, error-free signal transfer **Watch outs** - All routing configuration lives in software, nothing to adjust on the box - Three ports is a ceiling once a fourth device joins the rig - Under 1,000 Amazon reviews, a thinner track record than the budget pick - Ports: 3 in / 3 out, 5-pin DIN - Connectivity: Single USB-C port - Routing: Standalone router and filter, configured via free UxMIDI Tools software - Protocol support: Notes, CC, clock, sysex, MIDI timecode, MPE - Compatibility: macOS, iOS, Windows, Android, Linux, Chrome OS - Weight: 3.49 ounces - Dimensions: 2.56" x 3.29" x 1.32" Product page: https://mid1.com/product/cme-u6midi-pro-b0bffqgb33 ### Premium Pick: iConnectivity Interface with 4 in x 4 Out 5-pin DIN-MIDI Ports (mioXM) Our rating: 9.1 out of 10. Best for: A whole studio's MIDI gear, or a stage rig with several computers and instruments, routed through one hub. The iConnectivity mioXM is a routing hub for a studio, not an interface for one synth. 4 in / 4 out of 5-pin DIN pairs with 4 USB-MIDI host ports and an Ethernet RTP-MIDI network port, so DIN gear, USB gear and networked computers all land in the same box. The Ethernet MIDI networking is the real feature: 12 virtual network ports can be assigned across the DIN, USB and networked connections, which gets around the USB cable-length and port-count limits that force smaller interfaces to sit right next to the computer. A capacitive touch panel stores up to four user-definable presets, and class-compliant USB devices need no drivers. None of that is free. At roughly five times the budget pick's price and 3.4 pounds in a full-size box, it is built for a rig with real routing to do, not a single keyboard. Buying it for one synth means paying for ports that never get used. **What we like** - 4 in / 4 out 5-pin DIN plus 4 USB-MIDI host ports for class-compliant gear - Ethernet RTP-MIDI networking with 12 virtual ports removes USB cable-length limits - Capacitive touch panel stores up to four user-definable presets - Plug and play, class-compliant devices need no drivers **Watch outs** - Overkill for anyone with one synth and no routing to do - Costs roughly five times the budget interface for routing most players never need - 3.4 pounds in a full-size box, not something that lives in a gig bag - DIN ports: 4 in / 4 out, 5-pin - USB host ports: 4, for class-compliant USB-MIDI devices - Network: Ethernet RTP-MIDI with 12 virtual network ports - Computer connection: USB port, Mac and Windows - Controls: Capacitive touch panel, 4 user-definable presets - Compatibility: Mac OS X 10.11 or later, PC, iOS via Camera Connection Kit - Weight: 3.4 pounds Product page: https://mid1.com/product/iconnectivity-mioxm-b07y2rn1d4 ## Frequently asked questions ### Do I need a MIDI interface if my keyboard already has USB? No, if the keyboard has USB-MIDI built in, plugging it straight into a computer works without an extra box. A dedicated interface like the Roland UM-ONE Mk2 or CME U6MIDI Pro is for connecting older gear that only has 5-pin DIN ports, or for routing between more than one device. ### What is the difference between MIDI merge and MIDI thru? Thru repeats an incoming signal out to another device unchanged, so a message received on the in port shows up identically on the thru port. Merge combines two separate incoming MIDI streams into a single output, which is what lets two controllers drive one synth from the same cable. ### Is Bluetooth MIDI reliable enough to use on stage? For most performers, yes. Adapters like the CME WIDI Master are rated around 3ms of latency, which is not noticeable while playing, and the tradeoff is freedom from a cable rather than a real drop in reliability. A wired interface is still the safer choice if the connection absolutely cannot fail mid-set. ### What does class compliant mean on a MIDI interface? It means the operating system already recognizes the device without installing a driver, so it works the moment it is plugged in on macOS, Windows, iOS, Android or Linux. All three picks in this guide are class compliant. ### Is the iConnectivity mioXM overkill for one synth? Yes. Its four DIN ports, four USB host ports and Ethernet MIDI networking are built for routing between several pieces of gear or across a stage rig. One synth into one computer only needs the Roland UM-ONE Mk2 or a similarly simple single-port interface. ### Can a MIDI interface add noticeable latency to a wired setup? Basically no. Wired 5-pin and USB MIDI interfaces run well under a millisecond of added latency, which is inaudible while playing. Latency only becomes a real factor once Bluetooth MIDI enters the chain. --- Disclosure: mid1 may earn an affiliate commission on purchases made through our links, at no extra cost to the buyer.
