I missed their concert here in San Diego. But according to my friend they are using 2 mini keyboards. I believe it's DX100. does it have to a DX100? Can we use any other keyboard. Which patch or sound from DX100 does Roger always used to obtain that effect? Those harmony like in the song "Computer Love" is it achievable with only one voice using that talkbox and at the same time playing chords in the keyboard?

Thanks,
Dan
