Re: CGS28 on 12v?

Okay, I wired up some TL074's as a buffer.

I connected the +VCC pins on the TL074's to the +VE out on the Seq Switch PCB.
I connected the -VCC pin on the TL074's to ground. (Should this go to the -VE out on the Seq Switch board?)
I connected the pot wiper to the +IN on one of the opamps on the TL074.
I connected the -IN to the output.
I connected the output to the 3 Seq Switches.

I no longer get a voltage drop when it triggers on the same step on the 3 switches hooked up to the buffer however the range on the pot is very limited. With no buffer I have a range from 0V to 5V on the CV out but the step I have going through the buffer only has a range of about 0V to 1.5V.
