OK, I'm going to share a secret.

I wanted this plugin, to test a hunch, and the evidence so far supports my hunch.

John Medeski uses what sounds like a Clavinet played through an auto-wah stomp box. But he gets some interesting effects that sounds like he's also playing it through a wah-wah pedal, but not quite. He holds a chord and then while it's decaying the filter is opening at times, rather than closing.

Maybe he's got both a wah and an auto-wah, but I had a hunch that perhaps he has a VOLUME pedal on the clav, then from there into the auto-wah (and into a guitar amp, apparnetly, based on the distortion he can get). The volume going up would then open up the filter, which would otherwise follow the ADSR of the pick striking the Clavinet keys.

So, with Fons's plugin, I was able to get the same effect. I'm doing some Medeski, Martin, and Wood covers these days ;-).

I have the clav through the autowah. I use the volume/expression pedal on my keyboard controller.

I have several of the parameters of Fons' plugins set to a CC on my MIDI controller, using JACK-RACK, so I can adjust them while performing too.

And, now, I must go off to rehearsal :-)

Thanks, Fons!!
