ok, bear with me folks. i need a pedal that i can use as a synth source without any input from any other instrument (i.e. bass). the reason is i have vocoder capability in my boss se70 - it needs a vocal input on one channel and a synth input on the other and then i get vocoder output from them (link below is an example, it's the intro to a lord only tune from our 2nd cd.) http://lordonly.net/Mp3s/EDTestMix/dc1.wma in this example i used a keyboard to provide the sound source, but i'd rather not have to do that in the final run - would be sweet just to have a stompbox i could turn on to provide the synth that i needed for the se70 to spit out the vocoder goodness i want.
