Hi, first post. Nice to meet everyone! I'm interested in getting a midi controller for my DSL, and I have found a MeloAudio Midi Controller for sale. Has anyone used this with their dsl before? I've found one video on YouTube showing that you can use it to switch between all four "channels" (although officially the amp only has 2 channels). But unfortunately, it didn't show whether or not the midi controller can switch between the 2 master volumes nor did it show the fx loop being switched on and off. Switching between the 2 master volumes is something I'd be very interested in, so I thought I'd sign up here and ask if anyone has experience using this controller to do so. I'd get the official Marshall PEDL-91016 footswitch, but it hasn't been released here in South Korea (gear always gets released a lot later here). Maybe I should also note that I have never used or messed around with midi before...I'm entirely clueless about it all.
