Bandpass effects is the neatest things, yupyup...! I wonder if you can do this with the modulation routings on the Xpander? It sounds to me like you could, if the software handles routings in a certain way, but that it wouldn't work if the software handled things in ANOTHER way. I'll have to try it.... -- mike metlay * atomic city * box 81175 pgh pa 15217-0675 * metlay@netcom.com --------------------------------------------------------------------------- I bow to the obvious superiority of a culture that coins words like "snog."

Dunno if you can do this, but here's a neat bandpass filter patch trick: Take an LFO and multiple the output of it. Send one out to an inverter, the other straight to one of the filter CV-ins. Then take the inverted LFO-out, and send it to the _other_ CV-in...voila! A _very_ weird phase-shifter-type effect in which, if you've got the VCF freq controls set right, the signal sent thru actually _vanishes_, the whoooshes back into place. Bandpass effects is the neatest things, yupyup...! D.A.C.
