Midi to expression signal

[JoPo]

Hi !
Impossible to find a midi to expression signal converter !
There is bunch of exp -> midi but not the other way. There are a lot of midi to cv converter but I'm not tha would work correctly at a pedal expression input. Indeed, an expression pedal is passive (usually ?) and is nothing more than a potentiometer.

But I'd like to control, for instance, a wah wah pedal which has an expression input. Because thay are more current than a wah pedal with a midi input !
I must precise that I don't want any prostage stuff !

I've found this :
https://www.sourceaudio.net/reflex-expr ... oller.html
But I'm not sure it does the job, so I contacted their support.

Who could help me ? Who is able to control a wah pedal from his daw ? HELP !

Saw this on thomman

Ah yes ! I forgot to ask to not speak about that one I already tried ! You can control EVERYTHING by midi on this pedal ... Except ... the FILTER CUTOFF !!! Or the wah pedal movment itself !!

After hours of searching, I've found that : https://www.theeffectfactory.com/produit/chromatron/ which looks pretty nice and controlable with an expression pedal !
That one too which have cry & talk mode : https://www.ehx.com/products/cock-fight

But I'm still swimming in the same problem : how to output a signal that would fit in an expression pedal input of an fx pedal ?
Untill now, I wasn't interested by fx pedal. And I'm quite estonished to be unable to find something that could just convert hardware midi output CC messages to go in an expression fx pedal input !

You basically need a Wah-pedal with CV input...
as that's what the potentiometer in a regular Wah does: it adjusts a voltage over a certain range.
But I don't think 'real' voltage specs on regular pedals will meet CV specs. Are you into DIY ?

Yes, for Eurorack...
Anyway ! After 2 days of researches, I give up ! And I'll use some of my eurorack midi --> cv modules ! As it's explained here at 1mn and few seconds : https://www.youtube.com/watch?v=oLuAXkBnIxo

Or if I have the Source Audio Reflex confirmation, I'll try it.

I’ve got the Reflex Pedal.
CV is great for my Studio Electronics synths.
But since I got the Physis K4 I don’t use it.

Really quality pedal.
They’re expensive, but if you want I can sell you mine for 100 bucks.
I used it for 3 weeks, it’s been sitting for 2 years doing nothing.
I’m keeping the DUAL Output one they make.
It sends to 2 destinations/

Reflex actually does 5 + CV.

Sorry to take so much time to answser... I miss time ! I wish I did not need to sleep.

Anyway. The Physis K4 is impressive ! But since my Solaris is arrived (The reason I miss time !), my old midi keyboard retired and left his place. So, no place for even the most sophisticated ever keyboard.

I'd like to modulate some pedal equipped with an expression input. And I'm totally amazed to notice that midi CC --> expression hardware interfaces are extremely rare !

I pm you for the next...
