I needed tech support through Audio PC but the device works fine. As always, Rob Amaral is the best at getting me the perfect solution for all my musical needs

Happy to report this connection works as promised, though one must keep in mind that everything must be plugged in, before plugging an adapter into your iPhone or it doesn't register. Yes you can control virtual instruments on garage band with this adapter without using the software disc included which is for PC connections.

In the very 1st moments of my purchase I was kindly greeted and had a talk about my musical likes.
With this info and great conversation we began to find the best yet cost effective product for my needs.
It seemed everyone had good Ideas and great info to help me get the job done for my needs.
I'm glad I choose Sweetwater.They make me feel like we're in the same group helping to achieve each others golds

After some research I bought this Midi Interface Cable because it was the cable of choice for my needs. I am using it to interface my Korg Volca FM2 with my Macbook Pro and Arturia Keystep 32 Keyboard. This allows me to connect the Volca FM2 to my MacBook Pro in order to us the DEXED and SYNTHMATA Applications (and some others) to edit the Volca FM2 sounds and also to Upload Sysex Files into the Volca FM2. At the same time I can use my Keystep 32 to play the Volca FM2.

Part of this review is to help others as the included instructions were useless.

It's important to first download the Drivers for the MacBook Pro (or what ever computer you are using, such as Windows), install them and then Restart youy computer. Once you do this the Roland UM-ONE-MK2 should be recognized by your computer. Also there is a little switch on the side that needs to be in the COMP position. It's TAB (Tablet) to the left and COMP (Computer) to the right as you face the unit. Make sure you set this before you connect it to your Computer (or Tablet). The switch is recessed and a bit tricky to see and move, I needed a thin paperclip to set it and was not sure at first if the switch even moved so I tried it a few times just to be sure and it did. Roland could have designed this a little better.

One of the important points about the Roland UM-ONE-MK2 is it handles Sysex File Transfer perfectly. Many of the off brand Midi Interface cables do not, they either drop parts of the file, corrupt it or won't transmit them at all.

Pros:
It works for my needs and has been 100% reliable
Cables lengths are long enough for most applications.
LED lights let you know it's functioning

Cons:
A bit Pricey but hey if it works it's worth it
Mode Switch could be easier to see and use
Included Instructions are useless
Not really a bit deal but I would have preferred they used the newer USB C Connector instead of the older USB A, so I am using an adaptor.

4 Stars because of the Mode Switch, Poor Instructions and Price

When Windows 11 couldn't find a workable driver for my Juno Gi Roland US suggested that I try the UM-ONE.
When it arrived from Sweetwater, I connected it to the Juno Gi and Windows 11 and my DAW recognized it and now I'm able to use my Juno Gi like before.

Simply put, modern electronic music wouldn't exist without Roland. Many of the electronic musicians here at Sweetwater cut our teeth on TR Rhythm machines and fondly remember programming our first TB-303s. We owe a good part of our careers to this amazing and innovative company. It's been fun to watch and grow right alongside Roland, as they've introduced wave after wave of revolutionary keyboards, digital pianos, and more. For example, Roland's V-Drum Kits continuously redefine the possibilities of electronic drums, beginning with SuperNATURAL technology to the latest Prismatic Sound Modeling. We're huge fans, and we'd love to tell you all about them. Whether you want a pocket-sized synth or a cutting-edge video mixer, if Roland makes it, then Sweetwater is 100% behind it.
