Ok, makes sense. I guess the iconnectivity and Kenton units are really all there is. Thanks

Or how about this? http://tascam.com/product/us-144/specifications/ Sorry, I wish I could figure this out on my own but I don't know enough about this process to be able to figure out whether these will work.

Thank you. That is helpful. Do you think this will do the trick? http://www.m-audio.ca/products/view/midisport-2x2-anniversary-edition

What I mean to say is, with the right converter (since the WK 7500 doesn't have a standard MIDI connection) can I use a MIDI foot controller (The one I have is the Behringer FCB1010) to access the sounds on the WK 7500? To give an idea of what I'm doing, I'm in a band where I sometimes want to play bass lines with my feet. The bass guitar sounds on the WK7500 are quite good, and I just want to be able to access those sounds with the Behringer. I DON'T want to have to use a computer (causes too many concerns for live gigs). Obviously I could just buy a suitable sound module for the Behringer (such as the Alesis Nanobass) but I'm trying to avoid the extra expense since I have a perfectly suitable bass sound already. Any solutions? Thanks
