Hi Alan,
I wasn't familiar with the Kansas song, so I googled that and listened to theirs first.
I like this cover. I'm not sure on the mix... Sounds okay to me, but I have to rely on Lynn's expertise here...
I've listened to some "MIDI" music in my time and there sometimes you can really tell that they are, especially when they are transcribed directly from sheet music. But this sounds quite good to me. I'd be interested to hear your method of getting this to sound more "human." And is it a guitar sampler that you use?
Is your other SoundCloud stuff MIDI? Big Hard Sun doesn't sound like a MIDI tune either.
cheers
andy
