Extensions for the Peak Controller

[eagles051387]

I'd like to request some extensions for the peak controller. Usually, it is
controlled by a sound that should be heard. Instead, I control mine with sounds
that shall not be heard: Sounds very low on octave, such that they can be used
as an LFO.

This makes the Peak Controller extremely powerful. I can use all kind of
oscillators that ZynAddSubFX offers, and also portamento, echo etc.

This, however, would make the following controls very useful:
An abs LED, which is set to true on default. If not set, it should not take
the absolute value of the input wave, but the signed value instead. An offset, like the "base" in the usual LFO Controller.
The current multipliers are really not enough for me. Add an additional
multiplicator wheel as in case of the usual LFO Controller.
An LED to mute the input, instead of playing it. This is optional, since
it can be easily replaced by adding a Gain effect behind the Peak Controller.
But in my case, it is always useful.

All this should be easy to code and I volunteer to do that.

Johannes Lorenz Has fix for this already
