[sdiy] Small Resistors and slider pots

[sasami at blaze.net.au]

I find rotary pots are better than sliders in ADSRs and 
everything else for that matter. There are two primary 
reasons for this. 1) For purposes of control, a rotary pot 
has an anchor point: its shaft. It is easy to put your hand 
up and adjust one by simply grasping the knob. Sliders by 
their nature tend to require one to rest one's hand on the 
panel to be able to adjust them accurately. I have both in 
my synth, and do not see myself ever using another slide 
pot.  2)For DIY, mounting them is hard.
