8 stages of phase! the pseudo stereo sounds great.

While I'm waiting for the board to come from Ray, does anyone have any ideas for mods?
By the way, Ray's PCBs are as good as they look in the pics - DAMN good :icon_wink:

edited to say (after listening to the fast rate sample) it needs hyperbolic sine LFO, but I can't see how it is going to get it...yet...

You can install phasefiltering in any OTA-based phaser.  Try it out if you haven't already.  Just take the 4n7 cap tied to pin 7 or 10 of the LM13700 and tie the other end to ground instead of to the 30k resistor.  That converts the stage from allpass to lowpass.
