I'm looking for a RE that allows you to shape CV signals and I've been demoing a lot of devices for this. One thing that I can't find is a RE that allows you to scale separate +/- amounts for a Bipolar signal but keeps the zero point in the same place. So if you want a knob to output 0.5 CV when turned to 100% but output -1.0 CV when turned to -100% while keeping 0 in the same place.

This thing is pretty good and allows you to modify curves, but it doesn't allow enough options for me, as it is designed for a specific purpose. Cool product though.

Here's what it can do with a linear CV input by adjusting the Curve control.

I managed to hack this together using Quadelectra Parametrix devices but there isn't a way to set the relative + and - percentages. Ideally I could set the lower section to 100% and the top section to 30 or 25%. And adjust the lines from a linear plot to a curve.

Boom. Zvork's CV can do the min/max thing with only a single device. With this and the EXP1 you have a lot of control over a linear curve.

You can use shape https://shop.propellerheads.se/product/ ... fo-editor/ to do this. If you set the speed to zero and drive the phase on the back with CV, its a mapping of -1.0 to 1.0 of whatever you draw.

Thanks I will try this. I've saved my trial of Shape but I'm going to try it over the next few days. The demo video is incredible.

Would this allow me to modify a single linear 'curve'? The main use for this is to modify a curve on a single CV output knob rather than modifying LFOs. The LFO just makes it easy to visualize how the curve is being modified.

There was a device that did exactly what you want. http://www.black-and-orange.com/re/revolt.html
Unfortunately it is not available anymore since the developer died and Props removed it from the shop.

Why was ReVolt removed from the shop? I don't get why the death of the developer would necessitate this. Not complaining, because I've got it - but it's such a cool device, a real shame not to be available any more for all those CV tweakers who came late to the party

What about CV Mutant?

Yes. When Shape is set to 0.0Hz, then the phase knob/phase cv input controls the playhead directly. So you can create any cv-to-cv mapping you can imagine.

IIRC the Black & Orange RE's were removed from the shop on request from his family.

Don't know about others but I find CV Mutant particularly hard to get my head around. I've had fun tweaking it to produce random fuckery, but when it comes to getting it to do anything specific... takes me ages to figure it out. The manual is terrible, would love to see someone do a really good in depth tutorial

Looking at this, this is exactly what I need. Unfortunately I didn't appreciate this when I was able to buy it! Shame that the B&O devices are no longer available in the shop. I'm hoping that another dev will clone the functionality of some of these devices as they are well thought out,

I agree. It's a shame the devices can't be just made free on the shop. I didn't know Brian but I'd have thought he would have preferred for his creations to be In use and available to people.

Off topic, but I wonder if we contacted the family and made a plea to put the REs back in the shop, they might reconsider. It's worth a shot. Perhpas they don't realize his devices are missed by many people. Does anyone know how to contact them? What was Brian's last name and country?

Hmmm I think his grieving family might have more pressing concerns

CV Mutant seems to be the most flexible for this. Shape is a great device but I can't get it to work for what I am describing: altering + and - values while keeping the centre point at 0. I need to weigh up CV Mutant vs Volt CB-1 but I think CV Mutant offers most control.
