The ARP Quadra Phaser clone.
(See http://home.t-online.de/home/jhaible/hj_sch.html , bottom
of the page, for details.)
But that is just one example for an exponentially controlled
Phaser. I have 2 other ones with exponential (V/Oct) inputs, too:
The Phase-12 (http://home.debitel.net/user/jhaible/jh_phase12_1.jpg)
eventually led to the MAM Phaze2 in a scaled down version
(see http://www.mam-germany.de/produkte/phaze2.html) - but
I don't know if they have kept the external V/Oct input or not.
(If they have not, it should be easy to retrofit (;->))
And the other one is in my JH-3 Modular, with 6 stages switchable
from LPF to APF in pairs and VC slope control.

Well, the point was that exponential CV is a "natural" and inexpensive
way to control a Phaser (just as it is for a VCF), and with the Shape
control of the MOTM VCLFO you can emulate some of the stranger
crop of Phasers with a simple exponential Phaser to some extend.

Next I try it on a VC Flanger. 8-)
