CGS 50 Morph Lag

Can anyone give me some info on this one?

I assume its Harry Bissel's lag? Is it a single lag processor per board?

I was gonna do some small boards with these and some other bits but will just go with Ken's if I can.

This is a cool module, with potentiometer control for shape curve (lin/exp).

If you don't buy any MOTM-820, go for it !

Regarding the 5uF cap that is required, can I use a 4.7uF polypropylene? I can not seem to find a 5uF polyester film....

Is it possible to use this as an envelope generator?

The idea was to use 2 morph lag modules, 1 slope detector and 1 analog logic to build an ADSR.

But what does the morph lag do if it recives a very short trig pulse? Is the attack portion of the morph lag just as long as the trig pulse is? So immediately after the pulse drops to 0V the morph lag starts to fall?

The idea was to patch the gate into the slope detect. and have the rising going to one morph lag and then steady going to the other. Then having them both going to the analog logics OR part - (one input of the logic needs to be attenuated to be able to set the sustain level). So the first morph lag sets attack and decay, and the second one sets release..

But this will only be "fun" if the morph lag can provide long enough slew rates for the attack and decay.

Though just using the morph lag for a gate signal might be as usefull? (But you'll only get a ASR then..).

Hope it's sorta clear! I might have messed it up a bit.

could anyone maybe throw some pointers my way on the wiring of this? mainly:

are the attack and decay pads for a switch, or a pot? there's no description on the site, so im assuming this board is mostly for people who have some idea of what they are doing, i.e. NOT ME.

also, at the "shape" pot, im only getting a range of NO lag to A LITTLE lag when sweeping thru the pot. is bumping this pot up to a higher value my solution, or could this be due to that fact that i put an elec cap(4.7) where the mylar cap should be?(didnt have any laying around, wanted to test it out).

thanks for the help.
