FW: Less stupid questions...

[Paul Maddox]

Roel,

   Capacitors thing is somelike the first two digits of the
value and then a multiplier... 101 is 1000 times smaller than
the 104, but I too get confused, I alwyas meter mine (my dvm 
has a capacitor checker).

   The polysix, yes the pots would HAVE to be scanned constantly
by the processor. say you load a patch with say a resonance of 0
but the pot is half way, why doesnt it jump? well the processor will
scan the pots and remember the values, it WONT apply them to the
current patch, it then constantly rescans them, if they differ from the
first value it applies that value to the current patch, if they are the 
same as before (ie they've not been moved) then it ignores it.
cunning system really, but it means have a fairly decent quick settling
ADC to do this.
 
   Paul

Subject:	Less stupid questions...

Thanks for the response on my previous questions, i'm
learning alot...

- One of you guys ever built a theremin? Comments on
this subject?

- Where can i find schematics for a simple DI box?

- What do the numbers on capacitors mean (104,
101,...) and how can you get their value without the
measuring equipement? (I'm going to buy a decent meter
one of these days... but still.)

- On the polisix, for example, you can store your
presets digitally, and modify them with a potmeter?
The value changes if you change the value of the pot.
How does this work? I suppose the pots aren't
constantly scanned by a processor???

Thanks
roel
