Murphy was at work. It was just over a year after I received my Edirol UM-3ex that I finally had the time to take it out of its packaging and try it out. It didn't work. No signs of life at all. I tried it with four different computers, four different drivers, four different operating systems and got no response at all. The warranty is 3 mo/ 1 year. I'll have to see if I bought it on a credit card with extended protection. The moral to the story is do every thing you can to try out a piece of gear right after you receive it, even if you don't have time to really get into it. This model is discontinued now. It's getting harder and harder to find a good mid-level midi interface. The 1-in-1-out midi interfaces are a dime a dozen, and the high end jobs are also available. Its in this multiple-in&out/under$100 level that the products are hard to find. It's a shame this one didn't work. ### ⭐⭐⭐ 3.0 out of 5 stars No Windows 10 Support *by T***S on Reviewed in the United States on December 25, 2015* I purchased one of these a number of years ago, and was happy with it. My only gripe was the form factor: Having ports on both the front and back side of the device leaves a mess of chords.The problem is that in order for the UM3EX to work correctly, it needs Roland's driver. The last driver update was for WIndows 8, and there is no support for Windows 10 planned. ### ⭐⭐⭐⭐ 4.0 out of 5 stars so much for so little. *by M***. on Reviewed in the United States on January 5, 2007* As is the case with many Edirol products, this little device gives you quite a bit for your dollar. It functions simply and flawlessly as a 3x3 midi interface, and you can daisy-chain up to 3 devices for 9x9 midi ports.My only real complaint is with the midi-thru functionality. There are no dedicated midi thru ports; instead, edirol has provided switches which, when enabled, echo the input ports at the output ports. This would be great, except, when you have the thru switch enabled, the device doesn't capture midi from the input port (at least not with my software). snaaaaaarfoh well, at this price, just buy a couple. You won't regret it.~Maitland --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/29041176-edirol-um-3ex-3-x-3-usb-midi-interface](https://www.desertcart.tn/products/29041176-edirol-um-3ex-3-x-3-usb-midi-interface) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-25*
