Last night I finally tried connecting my Boss MD-500 to the Altura. I’m still not positive how I got it to work but I had to go to the manual a couple of times. The Altura can now control the rate and depth of an effect running on the MD-500 – and it’s a multi-effect unit with a big array of them — which is the utter bomb. Not all effects pedals have MIDI in but the latest series from Boss I think does with all of them. So the Altura really wins on interoperability with other hardware, IMO. I feel like the biggest roadblock to my progress over the years with electronic music has been that most of the hardware in my price range all have issues working with one another or simply don’t. I’m really happy to see that the Altura does not have such problems.
