Hi, I am trying to understand and learn the “VCM Pedal Wah” There are several parameters, however, I cannot find in any manual explaining the meaning of: type, bottom, top, even pedal control is not clear, or output.

Where can I find help on that?

thanks, Eric

BTW, I am working on emulating the song Money by Pink Floyd for a Tribute
Band… and… you can imagine how essential nailing that tone might be.

The VCM Pedal Wah Parameters aren’t too difficult to comprehend - if you’ve used a real Wah Wah pedal, that is.  :-)

The Synthesizer Parameter Manual (http://download.yamaha.com/file/48523) defines many terms, but unfortunately they’re pretty vague when it comes to the VCM-related ones.

So, a little background:
The Wah effect is that of a sweepable bandpass filter. A range of frequencies is allowed through, while others are not. That range can be shifted up and down in frequency by the pedal.

Pedal Control determines how “open” the filter is. If set to a very low number, the filter is nearly or completely closed, so the pedal will have little or no effect. If set to a very high number, the filter is almost or completely open, and again the pedal will have minimal effect. Settings closer to the middle of the range of values typically give more desirable results.

Bottom and Top determine the range of the filter. The maximum effect is obtained when the the Bottom setting is “0” and the Top setting is “127”. See the Note in the Data List, mentioned below.

Resonance Offset shifts the filter’s resonant peak up or down in frequency, depending on whether the setting is positive or negative, and to what degree.

Direction determines heel/toe up/down response direction. It’s pretty self explanatory if you try the two settings.
 
Type determines at which frequencies (High, Mid, Low, Bass) the Wah should work well. Set it based on the sound you’re controlling.

Overdrive sets the amount of distortion generated, as if “too much” effect was applied.

Output determines the level of the effect applied.

See the XF Data List (http://download.yamaha.com/file/52366), page 101, for the range of settings available for each Parameter. Note that “When the value of Bottom is greater than Top, the sound will not be modulated and only the Bottom value is available.”

For all of the Parameter settings, experiment if you’re not sure. Nothing will break.  ;-)

You’re welcome.

 

EricMonroe -

I’m not sure which Voice names you’re referring to. Could you specifically mention some of them?

As to elsewhere…
There are reverb effects such as HD Hall, HD Room, and HD Plate. In those cases HD is an abbreviation of High Damp. Damping causes the reverb effect to decay more rapidly. The HD reverbs have a Parameter, High Damp Frequency - it determines to which high frequencies the decay will be applied. The Parameter can be set from 1kHz through 20kHz. A setting of 1kHz would apply the damping to that frequency and those above it - the 20kHz setting effectively applies no damping at all.

Ok, I see, I think that explains my voice names, as i think they are High Damp Reverb versions of a voice… I sent an attachment. Not sure where I got these voices from.

thank you again ;)

Those do seem to be renamed versions of factory Voices, some obviously including the full name of HD reverb types. Offhand, I’m not familiar with the source, either.
