Works Great!

We were having trouble making our older Roland Fantoms work with a Mac using MainStage 3 since Roland no longer supports drivers for the Fantoms. By using the UM-One cable, you can run out of the keyboard using MIDI and do not need drivers (for the Fantom you have to change from Internal to External in Single mode to get the midi data to transfer to a computer). After I figured that out, everything has worked great.

The UM-ONE was just ehat i was looking for.

I had been looking for some time for a Midi cable to use to upload presets onto an older multi-effect processor I had and my Sweetwater sales engineer recommended this one. I must say I really like it. It was really easy to use and it works with both my Mac and my PC. I recommend it to anyone looking for a midi cable.

i had several different midi to usb cables before this one, which have all not worked for me. Geoff Allen recommended this one to me (which was cheaper than the others) & after downloading the drivers from Roland, I am able to plug it in & everything works!

Roland UM-ONE

I was looking for a midi to usb cord for recording midi from my Roland V-Drums. Got the UM-One and couldn't be happier. Works great with V-Drums/Pro Tools and Toontrack EZ Drummer.
