Two PT2399 in series

[Thomeeque]

 Did somebody tried it?

How did noise rise up compared to use of one PT2399 only?

Is it possible to connect VCO pins (pin 6) of both and control f_s (delay time) by one pot?

(more questions to come )

Thanks, T.

Haven't put two in series (although I have two pt2399 based delay pedals, I've loaned one to my buddy), but I can tell you that using a dual-ganged pot would be the simplest and most hassle-free way of controlling both simultaneously.

Look at the BYOC Ping-Pong schematic in the project .pdf on his site.

Stereo Echobase Delay.  You can use the two chips to get longer delay, or go ping pong!  Very neat.

Of course, but if it was possible to simply conect both pins and control them by one branch, it would give you some nice advantages (e.g. if you want to modulate f_s, maybe better tracking etc.), that's why I'm interested..

Thanks to all, I'll check those links!
