CV smoother?

[xylyx]

Does anyone know of a [preferably free] CV smoothing RE? Something that would make the values of the CV curve output on the Matrix less stepped, for example?

Janitor

Or you can use LP audio filter.
Best for it - kHz Filter (or same).

Better yet, just use Pulveriser!

Janitor

It leaves the place smelling nice afterwards, too.

Ive tested Pulver and Etch - results have bipolar instead unipolar wave.
But if I use follower I receive isnt precise wave.

p.s.

I thought that’s what you were looking for, not the ‘precise’ stepped output of Matrix Curve CV?
If instead what you’re looking for is linear interpolation, that is to say a “connect the dots” rather than a step, then you need a different device. The only way to connect steps with straight sloping lines is if you already know the value of the next step, so no ‘external’ device can do this in Reason.

What exactly are you looking for (can you draw it)?

[ljekio]

I thought that was what TS was looking for.
And yes, as a result, the steps are smoothed out.

Missed this before:

"Ive tested Pulver and Etch - results have bipolar instead unipolar wave."

Pulverizer is only bipolar if you start with a bipolar source! If you feed it a gate, for example, the result is not bipolar. Make sure you set Matrix to unipolar if that's the results you're looking for.
I just checked to be sure, and if you send Pulveriser a unipolar signal from Matrix, the output is still unipolar.

My other point is that even with 'full' smoothing the shape will be curved, not linear because of how low pass filtering (slewing, lag generation) works.

But there are step sequencers that DO allow a smooth transition from step to step, a feature I happen to love using! My MiniBrute 2s has this as a 0-100% setting for each step. One of my favorite applications is creating a ramp up in the sequencer with full 'smoothing' between each step. THEN, set the sequencer to RANDOM and you get an excellent 'slow random' effect that is constantly moving randomly. But I digress…

Doesn’t look that way for me, looks very much like the other devices - how is it connected?
[with those settings Pulveriser’s output should look very much like the original input signal…]

Through Thor:
CV in - Audio out -- Audio in - CV out
Between audio in/out inserted Pulveriser (and other filters in my tests)

[xylyx]

Thanks for the suggestions everyone. The Janitor device does what I was looking for, so I'll use that.

Another solution - EXP1 Expression processor

I use Pulveriser because there is already a CV. Input jack, so connect directly from Matrix Curve CV output to Pulveriser Follower CV input. The only real reason to use Pulveriser over Janitor etc is that it is a Factory device, so every Reason user already has it installed. So, the best option if sharing, not at all important if not IMO!
I guess Pulveriser is not commonly thought of as a CV processor, but it’s always been there!

[ljekio]

Now it’s clear, I never used it follower separately.
I would like to know the opinion why such a picture when converting cv to audio is on these devices. Some filters (like kHz) give a normal image, some have similar spikes in plus and minus. I still don't understand why this is happening.

Indeed^. Thanks for the thread/replies.
