RE: [motm] Frequency Shifter - one 'final' question

2003-12-08 by Mark

If you are going to add numbers, they should go from zero to 10 (or 
whatever voltage its effect approximates), not -5 to +5.  A negative 
amount of shift makes absolutely no sense, based on what I've read so 
far.

Also, does the Fine Shift approach zero towards the center of its 
rotation??  If is does you might want to add a "-" and "+" to each 
side, and perhaps a "0" in the middle to reflect that.  If not, then 
I think there should be some indication that fully counter-clockwise 
is the least offset -- perhaps a "0" on the left side and and 
whatever voltage it approximates on the right side.

My understanding of module's function is that it shifts by greater 
exponential frequencies as the summed voltage (CV In, Initial Fine, 
Fine Shift) increases, and that a negaative voltage sum would be 
ignored.  Otoh, if you have it so that negative voltages actually 
swap the Up and Down outputs, then you have something unique :)
