Hi -T- i would like to know if a Wav. File loaded in the SD cars can be played while we play (say a pia o or guitar voice) on top... again, if such is possible, can we play using the entire keyboard key range? i believe Wav. Files do allow voice to be heard, but i have no idea how this translate to the Wk7600 by converting the file using the casio software. I suspect that a singer's voice would be transformed into something else, or nothing st all am I correct? I ask this because Mp3 can be convertes to wav., and i believe the wav. File can be converted to a sort of MIDi file using the casio software. i may be willing to get the wk7600 if these features are flexible enough to be operated and used. related to this, i am curious to know if a wav. file converted and loaded as a casio file on the wk7600 can be later worked with the machine's mixer to do things like mute the patter's base track, or the strings etc... would love some insight on this or possible ideas or solutions to work with this please m.
