hi group, especially florian,

i'm thinking about building a simple keyboard replacement - different
arrangement of the keys but still the tempered scale. i think i know
how i want to do it, but i'd appreciate any advice that anybody may have.

first question to florian (or anybody that has his book griffbereit):
on page 32 of your book "synthesizer" you have a simple diagram of a
control voltage generator, each resistance corresponding to one key on
the keyboard. what would you recommend as a suitable value for the
resistors and should i be using 5v as shown in the previous diagram,
or 12v as stated in the text

secondly, i intend to produce the gate by simply putting the control
voltage through a comparator - everything above 0v opens the gate.
does anyone foresee any problems here

and any other problems i've overlooked

all comments much appreciated,

stu
