Roland SH09 Noise and S&H, on +/-12V

[egasimus]

Another topic similar to my last one, and once again it's likely this will culminate in a nice little vero layout. I'm big on modulation generators now, I laid out an envelope follower yesterday and now I'm looking at this nice noise+S&H circuit:

Of course, my complete lack of understanding of transistor theory wouldn't let me know whether I would need to tweak some resistor values for running the circuit on 12V, so once again I ask for help.

Also, can a variable slew rate control be added to the schematic? There isn't much else I could want from it.

This looks fun!

Have you tried it in practice yet?  I might actually have most of what I need laying around!

Not yet - I've yet to build the envelope follower from my last thread. Since I fail at understanding circuits beyond a few basic building blocks, I was hoping someone could tell me whether I need to make any changes to the circuit for it to work on my +/-12V PSU.

I did make a vero layout in some free minutes, once I'm sure I don't need to make more changes to it, I'll share it.

I think it should work fine on 12 volts. For a slew control you could try a pot wired as a variable resistor between the first fet and the top of the 10n cap.
