[sdiy] Oberheim Xpander VCF

[harrybissell at wowway.com]

My opinion (and everybody has one...) is that the different
filter topologies do not sound radically different. The changes are
subtle. For example, My ProOne has 12db / 24db low-pass filter modes...
the 12 is a little brighter but if you didn't know which one was active you
might not notice so much.

Of course making it a bandpass or highpass is more obvious... but if you had
only ONE filter I bet you would not use highpass very often
