[sdiy] Sliders and envelopes

[Maarten Halmans]

I would like to build an envelope generator with Alps sliders, I can only 
get these sliders in 10k log or 50k lin. Is it possible to get normal times 
(something between 1 millisecond and  10 seconds) for the attack, decay and 
release stages without using a large timing capacitor? Of course I could go 
for a voltage controlled envelope generator, but than a lot more components 
are involved and I am not specifically looking for voltage control of these 
parameters.
Any ideas?
Thanks,
Maarten
