Auto-Wah and Clav... not quite

For several years I've lusted away over the Clavinet-through-Auto-Wah sound: the Stevie Wonder sound (also used notably by Herbie Hancock, Medeski, Martin and Wood, and others).

The problem is that either the LADSPA auto-wah plugin doesn't quite cut it, or the Clav soundfont I found on Hammersound several years ago doesn't have enough dynamic range to really make the thing "wah" in any noticeable way.

Am I doing something wrong here, or is the plugin not quite the best implementation, and if so, are there any better ones? Likewise with Clavinet soundfonts too.

What about using separate envelope follower and filter plugins to make your own auto-wah ?

cheers,
ernie

Hmm, thanks. Well after digging into it a bit, it seems as though a proper "wah" effect is an LPF with a resonant peak at the rolloff point:

Apparently very easy to do in hardware (2 transistors, couple caps, and an inductor), but I'm not sure where I'd find a LADSPA plugin with this particular frequency response characteristic.

Looks like Rakarrack has a wah, and "alien wah" (from Zyn?) and an auto-wah of its own. I'll try those instead.

Hi Ken,

Have you tried ecasound?
Here you will find some auto-wah presets (this is what google came up
with but I believe that file is installed by default with ecasound).
http://cvs.seul.org/viewcvs/viewcvs.cgi/*checkout*/sound/ecasound/effect_presets?rev=1.9

I used it on this song here:
http://creazone.ca/snd/mangermanger.mp3

I guess I tweaked it to my needs but it's been so long ago...

Not *quite* so simple, because the resonance increases as you sweep the
frequency up.  You're increasing the gain of the amplifier quite a
bit...
