Owner's Manual
Posted on 20/01/2016 by Few weeks ago I bought a Roland TR8. i needed to sync it up with music apps on my ipad. I'd looked at various options ... iconnect midi 2 being the obvious choice but that device has issues with ios I believe.

I decided to call Dawsons in Warrington (where id bought the TR8) to see if they could help ... spoke to a very helpful chap called Graham who suggested I try the Roland UM one interface.... he was confident it would work as he used one himself.... he was right.

After some initial confusion with midi in and out configuration i had the TR8 synced to the iPad. the interface looks slightly overpriced for what it is but it gets the job done. Great service from Dawsons and thanks to Graham for the advice.
