Exponential control in custom unit?

Hi, is there a way in having an exponential control in the custom unit?
I would like to have the control of several parameters scaled differently than linear…

I’m not sure, but if you use a global chain to process the input and mix feedback from the output of that global chain into itself you can create exponential control from linear input signals; try negative and positive gain for logarithmic and exponential respectively. Then map the output of the global chain into your custom unit input.

Ah yes, good idea. Although I try to avoid global chains, as I want to save what i‘m Building into a custom unit…
wasn‘t there a way to build Feedbacks just with custom units? Make a linear control, than put something into this control, and in the main custom unit feed it back itself?

Not really, well, unless you want to process the whole signal :slight_smile:

All this will change at some point and things like this will become easier!

hello @odevices, any opportunity to see exponential behaviour in custom controls ?
given the complexity of the ecosystem it feels to me that this is becoming more and more of a necessity in my patches. thank you for any shared information.

I feel like if you took a sample of an exponential curve you could use the sample scanner to turn a linear one into an exponential one.


I just had an idea that I haven’t tested yet (don’t have a 301 set up currently).

Would it be possible to map 1/4 of a sine wave to approximate an exponential control? Set a sine oscillator to 0 Hz, set the bias of the phase control so that it’s at the lowest value (trough of the waveform) and then send your control into the phase modulation input, with gain scaled so that it scans through a quarter of the sine wave (from trough to zero-crossing). Of course you’ll need to scale and offset the output of the sine osc accordingly so it’s not from -1 to 0.

It won’t be a true exponential function but it should be close. :thinking:

it will probably work (as we know we can use sine oscillators as waveshapers) but… in the end it is the same as loading up a waveform in the sample scanner i think.
which is cool but a way to perfectly map a f (frequency) parameter of whatever unit to the custom controls of a custom unit would be killer
