changing CV range

[mysteryroach]

Wondering if y'all can help me. I have a few pedals that can be controlled via CV. Most are 0-5V. However, I have a 0-8V one and a 0-3V one. I also have a couple on my wish list that are 0-10V, and -5-5V.

Just wondering if there are any purpose-built devices out there that can attenuate+amplify+offset a CV signal? Such that I can use a 0-5V CV generator with pedals that have a different range. Looking for something very basic - cheap and simple. Also, something appropriate for use on a pedalboard, rather than a eurorack module or something.

these are pretty useful too

You should ask someone to make you a small box that has :

- a CV input
- an attenuator for this CV input (i.e. a potentiometer)
- a voltage regulator to ensure that the voltage you get after that attenuator does not exceed a specified voltage. For example 3.3V for digital pedals, 5V ,etc. If you want several choices, a switch could be used for that. Or simpler : different outputs to avoid sending too high voltages to unprotected pedals.

That could be done in a small box pretty cheaply I think.

If you want to add offsets in the mix, then it gets more complicated and you're veering into modular territory...

Switchable zener to shunt overvolt condition to common. Shame about the 0-3 volts though, they should have prescaled the input so it's compatible with three volt logic in a world of (at least) -5 to +10 volts.

Making something fool-proof (limited to 0 to +3) would greatly reduce the range of other circuits, for example, the admittedly rough around the edges CV support in the Dirty Doper does not really kick in until you start hitting the +3 to +4 range, but then it'll purr nicely right up to the rails (pick your poison), so yeah different outputs would be the best bet to support the implementation of everyone's shimmy - but it does not design out the fumbling drunk factor that breaks shit in the first place.

i had done some broadcast/bandwidths with independent 0-5v and 0-9v outs linked to one input/exp/cv source.

Thanks for the advice. I live in New Zealand, so may hit up a local builder in my country first. Will let you (adam) know if I need you to make something.
