I found this in the archives: http://launch.groups.yahoo.com/group/200e/message/104 "You can also phase shift the filtered signal using spacial dynamics in the 227e. B and C are 90 degrees out of phase from A and D is 180 degrees out of phase from A. Mix the filtered signal back to the original signal - voila, a phaser. Try it with 1 signal sent to all channels of the filter with each channel set to a different center frequency." I seem to remember another post concerning the same issue... maybe in regards to the 259e sine output???.... but I can't find it at the moment. I don't have a 227e so I cannot comment or test it out. -tom --- In 200e@yahoogroups.com, "nicholas_kent" <zaum@...> wrote: > > Doesn't make much sense to me (But I don't own any modules).
