mix resistor values...

[Chris Crosskey]

HI Folks...
I'm in the finishing stretch of designing a little sequencer thingy....It's 
got 8 steps (I'll be working on a 16-step driver sometime soon I guess) and 
I've done most of the layout. I've tried to keep panel wiring to a minimum, 
can't avoid it for the LED's on each step I guess (there are two tricolours 
on each step) so each step has it's own daughter board that is held to teh 
panel by its pots. Each step has four pots for the CV channels (four off 
natch :-)) and a pair of push switches to control gates one and two to 
switch them in or out for that step. The LED's light up green for a gate 
that is switched in, and the current step position is indicated by the 
LED's lighting up RED..a gate that is both switched in and the current step 
position is orange...I liked it and I had a bunch of tricolours sitting 
around so WTH....Each step has an individual gate output and there'll also 
be a one pulse per step gate output with a variable gate length too...so 
four gate channels and four CV channels...

My question is....the CV's need to be mixed together (each of the eight 
steps per channel) and I was wondering...woulfd I be better off with 10k 
pots and 100k mix resistors into the amp or vice versa (ie 100K pots and 
10k resistors)?...Thanks for any advice....

BTW...my Atari Falcon has just had the first Eclipse graphics card sold in 
Europe (apparently) fitted into it....It's a 4Mb ATI Rage PCI unit with a 
PCI adapter to plug into the Falcon...I'm now cheerfully running in 
1280x1024 (natural highest rez of a Falcon is only 640x480)...Suddenly my 
PCB cad package no longer needs me zooming in and out all the time cos I 
can display a 160x100mm Eurocard on screen with a 1/20" grid turned on and 
see everything at once....I used to have to do a 200% ZOOM to see 1/20" and 
as it is the sensible grid for homebuilding PCB's to I habitually use 
it....It really speeds up layout cos I can always see all the 
board.....yeehah :-))
   Now I'm just waiting for the Tempest 200MHz/256Mb PPC accelerator and 
the promised cable modem/ADSL board (the PCI converter can handle more than 
one board at a time....high-speed comms is promised as soon as  BT and the 
other companies get their fingers out...Tempest due late this year....
