New modular block - a generic value knob / attenuvertor

I realize it's unlikely that it'll happen anytime soon, if at all, but I thought I'd make this suggestion, and at least it -seems- like a pretty easy module to add.

It would be really useful for Caustic's modular to have a module that's just a single knob, presumably from -1 to +1 with a notch at 0.  It would have an input and an output on the back.  If the input was used, it would function as an attenuvertor and multiply the incoming value by the knob value and send to output. 

If it had no input, it would just output the flat value, which would be really useful for some automation chains where, for example, you want to have the same value for the mod input of three oscillators, but with an increasing delay as the original value is changed.  Right now this is not doable from a single control, you have to automate them separately, but with this new module I could route it through a couple of delays and achieve this and then there'd only be one thing to keep track of.

I'm convinced that a flat value output knob would be amazingly useful in all sorts of other ways too, it's something I've wanted a couple of times.

I've tried to replicate this with all sorts of fancy setups, most using an un-noted oscillator, but nothing seems to work for an adjustable constant value.  If someone else has done it, please let me know.

 

Edit: Okay, not more than 5 minutes after posting this I find a post by Paulovski proving that I could actually make a constant value output with only three module slots, a dadsr envelope and a 2-1 mix, which are pretty common so maybe indeed this can usually be squeezed in as one module slot on anything that already uses a dadsr.  Thanks Paulovski!

That said, it would still be nice to have, and a lot more intuitive if this were a module in and of itself, and I haven't quite figured out inversion yet either.

Hello. I thoroughly agree. A module that did this is very high on my wish list. But I did have a slightly different plan. I don't see much point in an input when a mixer would do the same thing, but a single unit, constant control signal generator split to four outputs, each with a gain control would turn the Modsynth inside out. This wouldn't let you do anything you can't already do with an EG and a mixer or two (And you're right. There are a lot of things you can do with such a signal), but a module like this would let you do more of them simultaneously.
I'm quietly optimistic about any further development here, but I'm not holding my breath.
If the post you mentioned is the one I think you are referring to, there's an example of inverted filter tracking in the second file. Sort of. But the filter closes as you play up the keyboard.

I eventually built an inverter.  It took almost half a modular to do it, and needs to be carefully biased to the input signal, so it's not actually very practical, but it's possible.  If you could send signals from one modular to the other... but you can't, they get mangled along the way.  So, a module that can invert a signal would be very useful, even if it's its own one-block or something - but I still think an attenuvertor that goes from +1 to -1 times the signal would be most general purpose.

Second mixer from the left is the input signal, adjust its output to see the inversion.

Mixer on the far right is makeup gain, the inversion process divides the signal strength by 4, so that increases it again.

Leftmost mixer is routing and actually a mixer :)

Bottom mixer on the third row is used as the bias you're inverting against.

I'm not sure why you need so many mixers.
