Re: [Doepfer_a100] adjusting a1434 VCLFO

2018-03-15 by Nicholas Keller

Scale and offset is for the 1V/Oct control response, you don't want to touch those.  

I don't see jumpers on the boards for DC offset or rectifying, so you would need to modify.....or stick an offset/attenuator module on each of the outputs that require one.
